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

From the structure of the switch, "al" means moving contact (or moving contact knife), also have a group called "the knife"; "Control" means the static generator price contact, there are also called the www.dongfeng-motor.com static contact (" a "or" throwing "), as a result, single league double control can also be called "single- pole double-throw switch". "A" and "lian" confusing, anode and union says the number of moving contact knife, but we need to show the linkage relationship between the switch and switch with a "very", such as dark there are four buttons on the panel auto spare parts switch, but there squirrel cage induction motor has been no contact between four single switch, so we call SiLianChan switch, but commonly used three-phase power with between diesel alternator generator generator set air switch for each phase with close contact, so we called three pole switch. This kind of connection mode is more simple, one kind is the formal approach: three terminal in the switch, moving contact wire into the line, two static contact wire strands, another switch, two static contact meet before a switch to the two stages, moving contact line and zero line on lamps and lanterns; Another kind of nonstandard practice: two switches on the moving squirrel cage induction motor contact of all ac acmotor2.blogspot.com motor access to the same circuit, the zero line, two line on the static contact to the lamps and lanterns.
The high voltage proportional relationship to transform the 100 v or lower level standard secondary voltage, for the use of protection, measurement and instrumentation. At the same time, the use of voltage transformer can be high voltage and electrical isolation. Although also be in accordance with the working principle of electromagnetic induction voltage transformer equipment, but its electromagnetic structure compared with the current transformer is just the opposite. Voltage transformer secondary circuit is high impedance circuit, the size of the secondary current is decided by the impedance of the loop. Secondary load impedance, small secondary current increase, makes a in a component of current automatically to meet electromagnetic balance of the relationship between the primary and secondary side. A voltage transformer is, as it were, structure and using a limited form of special transformer. Electromagnetic single phase motor current transformer is widely used in power system (hereinafter referred to as "current transformer"), its working principle is similar to the transformer.
The principle of current transformer wiring, as shown on the left. The characteristics of the current transformer is: (1) a coil in series in the circuit, and as a result, the number of turns in a coil current depends on the load current of the circuit under test. And has nothing to do with the secondary current; (2) current transformer secondary coil of the current meter and relay to the coil impedance is 220v 1.5kw ac motor very small, so under normal circumstances, current transformer run in to a short-circuit condition. The ratio of the current transformer primary and secondary rated current, called the rated mutual acmotortrading.blogspot.com inductance of the current transformer ratio: kn = I1n/I2n Because of one coil rated current I1n standardization, secondary coil rated current I2n unification of 5 (1 or 0.5), so the rated mutual inductance current transformer ratio have also been standardized. Kn can be approximately expressed as transformer primary and secondary winding turn ratio, namely the kn material kn = N1 N2 / type of N1, N2, for one, two coil number of turns.
