Connection with pole change motor

Can I connect a pole change motor (4 poles to 8 poles) to the inverter?
The motor is used for the exhaust fan, and energy saving and variable speed are concerned. Is using the inverter effective for them?
Category : 

Answer

Since the inverter allows for changing speed, fix the number of poles when using the pole change motor.
It is recommended to fix the number of poles to four unless large torque is required at low speed.
By operating the motor with the inverter at a speed lower than the power supply frequency, the power is reduced in accordance with the low speed and you can save energy.
