synchronous motor spee, synchronous speed in asynchronous motor
1 "Synchronous speed means that the rotor speed of the motor is the same as the rotating magnetic field speed of the stator winding.
2 "When the asynchronous motor is running, there is a certain difference between the rotor speed and the stator rotating magnetic field, which is slightly lower than the stator rotating magnetic field speed and is called asynchronous.
3 "When the asynchronous motor is running as a generator, the prime mover drags the rotor rotation speed to the magnetic pole, frequency, and time. Relationship:
Synchronous speed: N = 60 f/P
(f = power frequency, P = logarithm of magnetic poles)
