[QUOTE="Sidewinder, post: 540900, member: 9512"] What are the individual winding resistances on the motor, including the supply cables as measured at the soft start end? Wiring connected motor end, disconnected soft start end, Can you do LCR readings for this as well as high accuracy low resistance measurements? 0.00 Ohms is meaningless. You need to measure the winding resistance to check for damage in the form of turn-to-turn shorts or open turns. This is a start towards checking motor winding imbalance. All readings will need to be within 10% of each other. The absolute value is of less importance. To help any more, greater information on the application will be required. [/QUOTE]
