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

Combination switch HZ5 series

Stepper motor at low speed is easy to appear low frequency vibration phenomenon. Vibration frequency is associated with load and drive performance, it is generally 3 phase induction motor believed half frequency vibration frequency for the motor no-load takeoff. This determined auto spare parts by the working principle of single phase motor stepper motor in low frequency vibration phenomenon is very bad for the normal operation of the machine. small diesel engine When the stepper motor work in low speed, general damping technology should be adopted to overcome the low frequency vibration phenomenon, ac synchronous generator such as add single phase induction motor damper on motor, or drive the segmentation technology, etc. Ac servo motor running smoothly, even in the low speed also won't appear when the vibration phenomenon. Ac servo system has a resonance acmotortrading.blogspot.com suppression function, can cover the mechanical rigidity, and internal system has the function of frequency squirrel cage induction motor resolution (FFT), can detect the mechanical resonance point, is advantageous for the system adjustment.

The structure of the ac servo motor stator is basically similar to capacitance split-phase single- phase asynchronous motor. The stator is equipped with two position difference of 90 ° winding each other, one is Rf excitation winding, it always pick on the ac voltage Uf; L, another is the control winding connection control signal voltage generator Uc. So is also called the two ac servo motor servo motor. Ac servo motor rotor squirrel-cage often make it, but in order to make the servo motor has electric water pump a wide speed range, linear mechanical properties, there is no "rotation" phenomenon and the properties of fast response, it is compared 3 phase induction motor with the ordinary motor, should have the characteristics of small rotor resistance and moment of inertia of the two.

The rotor current is widely applied structure has two small diesel engine forms: one is using high diesel generator set resistivity of conductive materials high resistivity of the conducting bar cage rotor, in order to reduce the rotational inertia of the rotor, the rotor doing long and thin; Another kind is made of aluminum alloy hollow cup rotor, glass is very thin, only 0.2 0.3 mm, in order to reduce the magnetic resistance of magnetic circuit, should be placed in the hollow cup rotor stator fixed. The hollow cup rotor moment of www.facebook.com/guohong.trading inertia is small, responsive, and stable running, so widely used. Without the control voltage ac servo motor, the stator is water pump price only produced by the pulse excitation winding magnetic field, rotor motionless. When a control voltage, stator and then produce a rotating magnetic field, the rotor rotate along the direction of the rotating magnetic field, in the case of constant diesel alternator generator engine load, the speed of the motor changes with the size of the control voltage, when the control voltage of opposite phase, servo motor will be reversed.
