We repair the Midimaster Vector drive at our modern repair facility.

Our expert engineers have vast experience in fixing these kinds of drives.

The Midimaster Vector drive is a standard drive that can be used for controlling a 3-phase motor. Also, the drive has sensorless vector capability.

Sensorless vector control means the Midimaster can calculate the changes required in output current and frequency to keep the necessary motor speed with a broad variety of load conditions.

This precision control means the energy used by the machine is perfectly calibrated. This kind of control saves energy and therefore money. You can improve your bottom line while also helping the environment.

The 75 kW Midimaster is suitable for tough environments and heavy loads so it is designed to withstand industrial settings.
