I have a 120 HP 460 VAC Inverter duty motor driven by a VFD, yesterday the drive tripped on output overload. While checking resistance between the load size terminals to the motor (which were isolated from the drive and only connected to the motor) I measured a very low resistance of .1 ohm between windings. I then checked the leads to ground and found that the circuit is grounded, which I still need to troubleshoot. I thought the reading between windings was low so I checked another similar drive and motor and found the resistance between windings low as well. So what would be a normal reading between windings? I thought a reading of a few ohms was the norm.
