Level 6 motor magnitude 8 what meaning be?

1. The number of reflect the synchronous speed of the motor, 2 pole synchronous speed was 3000 r/min, 4 pole synchronous speed was 1500 r/min, 6 pole synchronous speed was 1000 r/min, eight pole synchronous speed was 750 r/min. Winding motor vehicle spare parts the way go to form a loop, namely pole logarithm, come in pairs, extremely is the meaning of magnetic pole, the winding magnetic field when an electric current, there will be a pole. . Each group of three-phase ac motor coil produces N and S poles, each motor each phase contains the number of poles is very few. Due to the magnetic poles are paired, so the motor with 2, 4, 6, 8... Extremely. 2. If the frequency of the three-phase ac 50 Hz, the synthesis of the synchronous speed of the magnetic field of 50 r/s, which is 3000 r/min. If the rotating magnetic field of the motor is not just a pair of magnetic poles, further analysis can also get synchronous speed n. and the relationship between the logarithmic p magnetic poles: n = 60 f/p.f for frequency, the unit is Hz. N units for r/min. The ns and pick up the frequency of the alternating current (ac) (f), electrical magnetic pole has strict relationship between log (p). The ns = f/p in China, the power frequency 50 Hz, so the diode motor wholesalemotor.blogspot.com synchronous speed is 3000 RPM, quadrupole motor synchronous speed is 1500 RPM, and so on. The speed of the rotor asynchronous motor is always less than or more than its. The speed of the rotating magnetic field, asynchronous in the name of the resulting. 


The difference between the rotational speed and rotating magnetic field of asynchronous motor rotor (called slip) usually within 10%. Thus, the ac motor (either synchronous or asynchronous). Speed is the restriction of the power frequency. Ac motor speed control, electrical motor therefore, is hard, the best way is to change the power frequency, whereas in the past to change the power frequency is more complex. So before the 70 s, in the required speed. Occasions, multi-purpose dc motor. With the development of power electronic technology, the ac motor frequency control of motor magnetic generator speed technology has started to get practical. 3. The synchronous motor speed = polar logarithmic x frequency (power frequency 50 hz) in our country, the asynchronous motor speed = extremely logarithmic x frequency - logarithmic * slip frequency. In addition, the same power of motor, the greater the speed, the smaller the output torque. 4) of synchronous motor pole: the large capacity of synchronous motor are turning pole type, namely the rotor magnetic pole, is produced by passing a dc excitation winding, and synchronous machine very logarithm is the logarithmic rotor magnetic pole. Eight pole motor rotor is eight pole, 2 p = 8, namely the motor with 4 poles. Steam turbine generator is non-salient pole type motor, more commonly a logarithmic rarely, generally for 1, 2, and n = 60 f/p, so his speed is high, up to 3000 RPM (frequency), and the number of hydro-generator. Quite a lot, for the salient pole rotor structure, the process is more complex, because the number of his lot, so he has a very low speed, perhaps only a few turns per second

The design of the fuzzy control rules generally includes: choose the word set of input/output variables, define a fuzzy variable fuzzy subsets and establish the control rules of fuzzy controller. The word set input and output variables, as a general rule, be {NB, NM, NS, NO, PO, PS, PM, PB}. Fuzzy variables of the fuzzy subset is to determine the shape of membership function of fuzzy ac electric motor subset.

The application of squirrel-cage asynchronous motor soft starter - the traditional method for motor starting

Squirrel-cage motor direct total pressure of the large current when starting the motor stator coil and produce very big impact,rat cage bar damage caused squirrel-cage winding insulation and faults,cause 8500w gasoline generator motor failure; Large current will produce a lot of heat,winding insulation damage,reducing the life of the motor.Can be used to increase the power distribution capacity or limitation of motor starting current method to solve the above problems.If only increase the distribution capacity for starting motor,it is not economic.Therefore,usually equipped with limit starting device of generator generator set motor starting current.The commonly used methods are: 1) the stator cascade reactor or resistance starting.Stator reactance starting,reduces the starting current,but also reduces the starting voltage and starting torque is reduced more.Therefore,stator reactor step- down starting applies only to the electrical motor light load motor starting. 


2) ya a delta step-down starting.Ya a delta step-down starting is also applicable to the light load motor starting,and limited to the normal operation of delta connection of the motor.Louboutin leather plant low pressure air compressor motor is to use this way. 3) the autotransformer step-down starting.Using autotransformer step-down starting,compared with the direct starting,starting voltage reduced a lot (for the rated voltage of 1/4,1/7),and the starting torque to reduce more; And autotransformer is wholesalemotor.blogspot.com not allowed to frequent starting,which limits its wide use. 4) yanbian triangle step-down starting.Yanbian triangle is made after the starting of motor,tap can't change,limiting the application of yanbian triangle starting method.These belong to step decompression starter,start-up mode and obvious shortcomings,namely the secondary impact appeared in the process of starting current.

The application of soft start the motor?

Widely used in coking production process equipment such as fan, water pump, and belt conveyor,

generally need to directly under overloading starting motor, starting current is as high as 8 =;

Times, power supply network voltage drop is too large, to be the impact of the driven equipment and

control equipment failure rate is high.www.facebook.com/dongfeng.motor To solve

the problem of high power motor start-up, generally USES the frequency-sensitive rheostat, since the

lotus root transformer, B C % conversion and yanbian triangle startup mode, etc. But the traditional

way of step-down start widespread starting equipment complex, small starting current and starting

torque, etc. And the operation of the protection in motor, there are imperfect or insensitive. In

recent years, with the development of power electronics technology and its related devices, three-

phase asynchronous motor soft start technology has become increasingly perfect, and has been widely

used. Soft starter is composed of microprocessor and high power thyristor, with microprocessor

control thyristor conduction Angle, to control the output voltage. Therefore, the soft starter is

actually can automatically control the step-down starter. Because you can adjust the output voltage

and current closed-loop control, so be better than the series resistance and autotransformer such as

traditional step-down starting way. Drum cold section in our factory now chiller water circulating

pump motor as an example, the motor power < 95 DE, rated current 755 f, rated voltage 7 > 56, 755

(power lines, cable main section < 45 (4 pairs of power supply and the main transformer capacity <

555 d6f, motor overload starting. 1, the total pressure directly By the relevant calculations,

short-circuit capacity of power motor part system bus voltage drop in 437, the motor terminal voltage is the voltage of 89: left and right sides, directly below the motor starter needed; 6: the requirement of the terminal voltage, hard to conform to the requirements of the launch, it must adopt step-down start. 2, autotransformer step-down start Calculation result is: the < = > 3? ; 3 @ 7 a, B = * > 3? 29 the C7, B = > 3 D? "2" "C7E F = >" 351.

Using autotransformer buck up, there is the startup time is too long, start the difficulty and the

need to increase a step-down starting set of problems. And the failure rate is higher, the startup

current impact on motor is extremely adverse. 3, magnet generator  soft starter start Soft starter starts, not only the operation is simple, and can be obtained from the motor initial starting torque, starting voltage can be increased. Selects the kick start function, can provide big promotion for motor torque, in

order to overcome the inertia of load and quickly complete the boot process, the actual starting time

of 261. By drum machine cold section in the practical application showed that the circulating water

pump motor soft start technology not only can provide flexible start mode and excellent start

features, can also provide soft start, soft start of belt optional kick start, current-limiting

starting, double ramp up and started full pressure, etc. In addition, can provide various operations

of protection, fault conditions directly read operation parameters of the motor, fault self-diagnosis

function, with stepless regulating switch to eliminate the system of contact. Humanized menu

interface can easily access or modify the parameters, to achieve centralized control through

additional communication network interface. Also can effectively reduce the startup of mechanical

stress, reduce the impact to mechanical transmission components.

Seven methods for three-phase asynchronous motor drive

The seven kinds of three-phase asynchronous motor control method and characteristics:Introduces seven kinds of three-phase asynchronous motor speed control mode and its characteristic, pointed out its

applicable occasions and situations. For three-phase asynchronous motor speed formula: n = 60 f/p (1

- s) from the type, change the power supply frequency f, slip ratio of the motor very logarithmic p

and s can be too much to change speed.A,classification:1,from the www.facebook.com/dongfeng.motor perspective of the nature of speed regulation,different way of speed adjustment is nothing but change synchronous ac motor synchronous speed or not turn two. Don't change the synchronous speed control methods are: 1) the wound rotor motor rotor series resistance speed dc chopper, 2), 3) cascade speed regulation and application of the electromagnetic slip clutch, 4) hydraulic coupling, such as 5) oil-film clutch speed regulation. Don't change the synchronous speed of speed regulation method is widely used in the production of machinery.2, the change of the synchronous speed logarithmic multi- speed motor, stator can change of the stator voltage, frequency, frequency control of motor speed has no commutator motor speed regulation and so on.

3, from the energy point of view, when there are 1) high speed control method and (2) low speed regulation method two: an induction refers to the effective speed control is constant, so there is no slip loss, such as multi-speed motor, frequency control of motor speed and slip loss can be recovered speed control methods (such as cascade speed regulation, etc.). Have slip loss speed regulation method belongs to the low speed, such as rotor series resistance speed control method, the energy loss in the rotor circuit; Electromagnetic clutch speed regulation method of energy loss in the clutch coil; Hydraulic coupler speed regulation and energy loss in the oil of hydraulic coupling. In general slip loss increases with expanding range of speed regulation, if the speed range is not big, energy loss is small.A, logarithmic pole change speed regulation method: this method of speed control is in change of the stator winding red way to change the speed cage motor stator polar logarithmic to achieve. This method is suitable for don't

need a stepless speed regulation of production machinery, such as metal cutting machine tools,

elevators, lifting equipment, fan, water pump, etc.Characteristics are as follows: 1, with a hard

mechanical properties, good stability; 2, no rotor cutting machine slip loss, high efficiency; 3, simple

wiring and convenient control, low price; 4, have used differential is bigger, cannot obtain smooth

speed regulation; 5, can be used with regulating speed control, electromagnetic slip clutch, smooth

speed characteristics of high efficiency. Second, the method of frequency control of motor speed:

frequency control of motor speed is to change the frequency of the motor stator power, to change its

synchronous speed control method. 

Variable frequency speed regulation system is the main equipment to provide frequency conversion power of inverter, the inverter can be divided into ac - dc - ac frequency converter and ac - ac frequency converter two kinds big, cross - straight - to pay inverter are mostly used in China at present. This method is suitable for the requirement of high precision, better speed control performance. Its features: 1, high efficiency, speed the process of no additional loss; 2, wide application range, can be used in the cage type asynchronous motor; 3, large range of speed regulation, and the characteristics of hard, high precision; 4, complex technology, high cost, maintenance difficulties. Three, cascade speed regulation method: cascade speed regulation refers to the wound rotor motor rotor loop series adjustable the additional

potential to change the slip of the motor, to achieve the purpose of speed control. Most of the slip

power is absorbed by series of additional potential to recycle produce additional device, the

absorption of returning the slip power grid or conversion of energy use. According to the slip power

utilization way, cascade speed regulation can be divided into motor cascade speed regulation,

mechanical cascade speed regulation and thyristor cascade speed regulation form, adopts thyristor

cascade speed regulation. This method is suitable for the ac synchronous motor fan, water pump and the rolling mill, mine hoist, the extrusion machine use. 

Its characteristic is: 1, but will slip loss in the process of speed feedback to the grid or production machinery, high efficiency; 2, unit capacity is proportional to the speed range, saving investment, apply to speed range in production machinery from 70% to 90% of the rated speed; 3, speed regulating device failure can switch to run at full speed, avoid production; 4, thyristor cascade speed regulation low power factor, harmonic impact is bigger. Four, wound rotor motor rotor series resistance speed control methods: wound rotor asynchronous motor rotor string into the additional resistance, make the slip of the motor, motor under low speed running. The series resistance, the greater the lower the speed of the motor. This method is simple, easy to control, but the slip power consumption in the form of heat on the

resistance. Step speed, mechanical properties of soft. Five, the stator voltage regulating speed

control methods: changes of motor stator voltage, be able to get a different set of mechanical

characteristic curve, in order to gain different speed. Due to the torque of the motor and the

voltage is proportional to square, thus maximum torque decreased a lot, the smaller range of speed

regulation, and makes difficult to apply general squirrel-cage motor. In order to enlarge the speed

range, regulating speed rotor resistance value should be adopted for the big cage motor, such as

torque motor, USES for regulating speed or frequency on the wound rotor motor series resistor. 

In order to expand the stable operation range, speed above 2:1 Settings when feedback control should be

adopted to achieve automatic adjustment speed. Regulating speed control is a main device can provide

voltage change of power supply, the current commonly used ways with saturable reactor in series

voltage regulator, autotransformer and thyristor voltage regulation. Thyristor voltage regulation

mode is the best. Regulating speed generally applicable to the production machinery under 100 kw.

The characteristics of the pressure regulating speed: 1, the pressure regulating speed control

circuit is simple, easy to realize automatic control; 2, in the form of heat transfer differential

pressure regulating process power consumption in the rotor resistance and low efficiency. Six,

electromagnetic speed regulating motor speed adjustment method: by cage motor electromagnetic speed

control motor, electromagnetic slip clutch and dc excitation source (controller) of three parts. Dc

excitation power is small, usually by a single-phase half-wave or full wave thyristor rectifier,

change the thyristor conduction Angle, can change the size of the field current. Electromagnetic slip

clutch armature, poles and excitation windings of three parts. The armature and the latter is no

mechanical contact, can free rotation. Armature and motor rotor coaxial connecting said active part,

by the motor drive; Pole docking with the shaft coupling and load according to secondary part. When

the armature and pole are static, such as passing a dc excitation winding, the surface will form

several along the air gap circle on N, S alternating polarity magnetic pole, the magnetic flux

through the armature. 

When the armature motor rotates with drag, because of the relative movement between the armature and pole, thus make the armature induced eddy current, the eddy current and magnetic flux interact to produce torque, driving a pole rotor according to the same direction, but its speed constant is lower than the speed of the armature N1, this is a way of slip speed, change of slip clutch dc excitation current, you can change the clutch output torque and rotational speed. This method is suitable for medium and small power, the requirement is smooth, short-time running at low speed production machinery. Electromagnetic speed regulating motor speed control features: 1, device structure and the control circuit is simple, reliable operation and convenient maintenance; 2, speed smooth, stepless speed regulation; 3, no harmonic of power grids affected; 4, the speed loss and low efficiency. Seven, and hydraulic coupler speed regulation method: hydraulic coupler is a kind of hydraulic transmission device, generally consists of pump wheel and turbine, working, they referred in the seal housing. Into a certain amount of working fluid in the shell, when the impeller rotates, under the prime in the liquid by the rotating blades to promote, in under the action of centrifugal force along the outer ring into the turbine and pump wheel is on the same shift to the turbine blades to thrust, the mechanical operation of the production. Hydraulic coupler shell power transfer capacity and the relative to the size of the amount of liquid is the same. In the process of work, the change rate of liquid can change coupler turbine speed, achieve stepless speed regulation. This method is suitable for the fan and water pump speed. Its characteristic is: 1, the power to adapt to the scope is big, can meet different power from tens of kilowatts to thousands of kilowatts of needs; 2, simple structure, reliable operation, convenient use and maintenance, and low cost. 3, small size, can let big; 4, convenient control, easy to realize automatic control.

Brushless dc motor electrical engineer

In electrical engineer brushless dc motor and dc motor has the same working principle and application characteristics, and its composition is not the same. In addition to the motor itself, the former is more than a commutation circuit, the motor itself and the reversing circuit together. Many small power motor of motor itself is integrated with commutation circuit, look from the appearance of brushless dc motor and the dc motor are exactly the same. Brushless dc motor of the machine itself is electromechanical energy conversion part, it besides motor armature, permanent magnet excitation two points, also with sensors. Motor itself is the core of the brushless dc motor, it is not only related to the performance index, noise, vibration, reliability and service life, etc., involving the manufacturing costs and product cost. Because use permanent magnet magnetic field, make the brushless dc motor from the traditional design and structure of the dc motor commonly, meet the requirements of various applications market, and development in the direction of the province copper material saving, simple and convenient manufacturing. 

Permanent magnet magnetic field is closely related to the application of permanent magnetic material, the development of the third generation of the application of permanent magnetic material, make brushless dc motor to efficiency, miniaturization, energy-saving direction. In order to achieve the electronic commutation must have a position signal to control the circuit. Early with the mechanical and electrical position sensor position signal, has been gradually use electronic position sensor or other ways to get position signal, the easiest way is to use the armature winding voltage signals as position. To realize the control of motor speed must have a speed signal. With similar position signal obtained speed signal, the simplest speed sensor is type tachogenerator frequency measurement combined with electronic circuits. Brushless dc motor reversing circuit consists of two parts, drive and control, it is not easy to separate the two parts, especially small power circuit integration between the two usually become single application-specific integrated circuit. In the power of the larger motor, drive circuit and control circuit can become one. Drive circuit output power, drive motor armature winding, and controlled by the control circuit. The driver circuit has from the water pump linear amplification state into PWM switch state, the corresponding circuit composition also from transistor discrete circuit into modular integrated circuit. Modular integrated circuit with power bipolar transistors, power field effect tube and isolation gate field effect in the form of a bipolar transistor, etc. Although, isolation bipolar transistor gate field effect the price is more expensive, but from the perspective of the safe and reliable performance 8500w gasoline generator with it is more appropriate.
