2. When is a motor with a frequency inverter used?

There are of course many different reasons for using a motor with an integrated inverter. Here are a few examples: This drive unit is often installed in a machine room or outdoors, where different speeds are required on the electric motor. Sometimes the motor connection cable is simply too long to operate the drive without faults. Often, only frequency inverter protection class IP65 is required. This means that no extra control cabinet is required due to the protection class. Complex measurement and control technology can also be used. In this case, the reduced commissioning time is the reason why a motor with inverter is used.
