What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
So that mainly depends on your application and the frequency of work in the number.
2, the ordinary asynchronous motor is the cooling fan and motor spindle connection, the motor speed determines the cooling fan speed, low frequency when the motor rotation is slow, so the motor temperature rise is the principle.
First of all you have to understand the difference between variable frequency motor and ordinary asynchronous motor.
1, inverter motor cooling fan is not connected with the motor spindle, is independent, the fan rotation from the motor speed, to ensure that the motor cooling.
