OK But to make sure, your motor needs to be changed to 3 phase 220 volts, The nameplate on your motor shell and the inside of the motor junction box tell you how to modify it And your motor must be a three-phase induction motor, not a synchronous motor If you are not sure, you can take a photo of your motor's nameplate and motor's junction box, and we will confirm it for you. The photo must be clear.

Yes, but you'll need to change your motor to a 3 phase 220. How to modify is marked on the nameplate and junction box of the motor.

If your motor can't be changed to 3 phase 240 then it won't work as the motor won't run to full speed. Only run up to 30 Hz if you're going to use top speed. Above this frequency, the torque will drop.

Yes, but the two motors need to be changed to three-phase 220V, and the two motors need to be started and stopped at the same time. In other words, no switch can be added between the inverter and the motor. If these conditions are met, there is no problem at all.

No, we don't have a 22kw Vfd.
