What is the motor drive for

Answer:

Ac motors can be controlled by a frequency converter. Like a dc brush motor, you don't need a drive if you don't need accurate speed and direction. But look at your explanation, it seems to be dealing with the power of ac motors. So you need a drive to get you started. (ac motor start time need for low voltage large current to start, after rotation, then return to normal rated current, rated voltage, this is all drives work.)
The motor is the motor, first of all you have to know how the controller of the motor is used to understand the classification and structure of the motor. Dc motor with brushless dc motor and dc motor. The brushless dc motor must have a drive to turn (commonly referred to as electrical). The dc motor can be turned by direct current, and if it is not accurate control of speed and control, no actuation is required. Ac motors can be controlled by a frequency converter.
