I just want to ask you if there is a Phidgets controller to control 4kW AC 3 phase motor and control motor speed. I found controler from different supplier which allow me to control motor spped by changing frequencie, but it will be fine to have all controlers from Phidhgets. Thank you so much for any ideas.

Phidgets does not currently supply 3-phase AC motor controllers.
That said, you may be able to use a Phidget to send a control signal to a third-party motor controller, depending on the control signals your controller will accept.
