The VFD manufacturers have white papers specifically covering driving multiple motors from one larger VFD so it's absolutely a supported configuration. You need separate overcurrent protection for each connected motor though since the VFD's OCP can't work to protect an individual motor in such a configuration.

I dont think that will work. Their rotors will never be in phase so any feedback generated is going to be really strange to the VFD. ron ginger On 11/25/2014 10:30 PM, [email protected] wrote: >>I need to drive 2 high-speed spindle motors, 3,7 kW each.
