If we need to proceedThree-phase asynchronous motorDetection, what tools to use, how to judge its good or bad? todayMori machineXiaobian will take you to understand the quality of testing AC three-phase motors.

    1We can use a dial to shake,500VShake the insulation resistance value of the line on the three terminals to the motor housing, if it is in0.5MThat means there is no short circuit to the ground.

    2Multimeter test: testA/B/CThe resistance value of the three phases, is equal, this value is almost, but too much difference can also turn; If the difference is too much then this oneThree-phase asynchronous motorIt won't take long; Remember that the larger the motor, the smaller its resistance value! But you can't do all three0Oh, unless you're really big, like50KWAbove motor!However, if the check is the speed motor then6The resistance value of each terminal is different.

    3Can check bearings, fans, generally wrapped motor let all replaced, because sometimes the bearing will burn the motor.

    4The no-load current of the motor is generally rated current10%～50%But sometimes the motor idling current is still zero.

    5When the motor runs with rated current, it belongs to full load operation, and the output power is basically100%. The running current is small, indicating that the output power of the motor is small, and it is light load operation.
