To determine whether a three-phase motor is in good condition, you can check from both electrical and mechanical aspects. The specific methods are as follows: Electrical Aspects 1. Measuring Insulation Resistance Use a 500V megohmmeter to measure the insulation resistance of the three-phase windings to the ground (motor housing) and between phases. The resistance value […]
