3 phase AC motor speed control using inverter drive
It is possible to connect the motor to a socalled VFD (Variable Frequency Device). Such a device can control the speed of the motor in a wide range.

From the power requirements a 3 phase version is needed. Therefore 380-400 VAC 3phase input. Then you have 3phase 380-400 VAC output. The obtained output is input frequency independant and can vary between 0 rpm ( external cooling required) and some 10 to 20% over the designspeed of the motor. Modern VFD's allow you to make a fully automated setup. However if the requirement become very specific manual setup might be needed.
