    Tips: Faults of AC Induction Motor
    The faults of AC induction motor are generally divided into two parts: One part is the mechanical reason, such as the damaged bearing or fan blade. The other part is the electromagnetism fault. The two are correlated. For example, the bearing damage will probably cause motor overload or even short circuit. The damage of the fan blade enables the motor winding to have difficult heat dissipation, increased temperature and low insulation. There are many reasons for electromagnetism fault. For example, motor overload, short circuit or voltage shortage can cause motor damage, in which, short circuit is more dangerous. In addition to the above, the reasons causing motor fault still include the following reasons:

    1. Too high ambient temperature, poor dissipation condition.
    2. High starting current of the motor or too long starting time.
    3. Long-term low-speed operation of the motor.
    4. Frequent starting and braking and so on of the motor.

    This 3/4 hp AC induction motor works
    Ordered this single phase induction motor to replace an old motor on a hay elevator. So far, no issues. It works as it should.
