What is the maximum speed of a three-phase AC motor?
The fastest is the 2 stage motor, near 3000 revolutions per minute
The maximum speed of the three-phase AC motor is determined by the power supply frequency and the number of poles of the motor. The maximum synchronous speed is =60*, frequency (50) / magnetic pole number (1), =3000 rpm, and the asynchronous speed is about more than 2900 revolutions per minute.
This motor is divided into pole number, 2 pole motor synchronous speed 3000RPM; 4 pole motor synchronous speed 1500RPM; go down and so on
Level two is close to 3000 rpm, does not include ultra high speed, ultra high speed has 6000
