Is it normal for the motor resistance to be 80 megohms?

Under normal circumstances, the resistance value of three-phase motor should be above 0.0 1 ohm, but not more than 1 ohm. If the resistance value of the motor exceeds 1 ohm, it means that the motor may have problems such as grounding fault or motor rotor sticking, and needs to be repaired or replaced.

The resistance value of motor is one of the important indexes to measure the performance of motor. Under normal circumstances, the resistance value of the motor should be within the normal range. Therefore, when repairing or replacing the motor, it is necessary to measure and adjust its resistance value to ensure that the resistance value of the motor is within the normal range to ensure the normal work and safe operation of the motor.
