How to convert the frequency of frequency converter into output speed

- Sep 09, 2019-

Synchronous speed of the motor = frequency *60/ logarithm of magnetic pole,

Asynchronous speed can be approximately calculated, according to the actual speed = actual frequency * rated speed /50

Formula of motor speed and frequency: n=60f/p.

Where n represents the motor speed (revolution per minute), 60 represents per minute (second), f represents the power frequency (Hertz), and p represents the polar logarithm of the rotating magnetic field of the motor.The polar logarithm is given on the motor nameplate and can be calculated by substituting it into the formula according to the actual situation.
