marke Posted May 23, 2012 Report Share Posted May 23, 2012 Hello Bonamotor Yes, you could connect to a VFD and increase the speed provided that you operate within the motor ratings.You can use a single phase input three phase output (230V) VFD with the motor connected in delta, or a three phase input three phase output VFD (400V) with the motor connected in star.
