If the meter shows a low resistance value or continuity, the winding is grounded, and the motor requires repair or replacement. Typical values range from 0.
Open Circuit Check 3 Phase Motor
Observe the rotation direction indicated on the motor nameplate. Verifying Disconnection Use the continuity function of your multimeter to confirm that the motor is completely disconnected from the supply.
The first step is to isolate the motor from the power supply and lock out the energy source. If the values are within 10% of each other, the windings are balanced.
Open Circuit Check 3 Phase Motor
Compare these three readings. If continuity is present, there is a wiring fault or a failed insulation barrier, and the motor must not be energized.
