    Top causes of single-phase motor malfunctions

    Most problems with single-phase motors involve the centrifugal switch, thermal switch, or capacitor(s). If the problem is in the centrifugal switch, thermal switch, or capacitor, the motor is usually serviced and repaired. However, if the motor is more than 10 years old and less than 1 HP, the motor is usually replaced. If the motor is less than 1/8 HP, it is almost always replaced.

    Don't run it backwards

    There's an old saying that the first time you hook up a three-phase motor it will run backwards. If you're lucky, it will only make you look foolish. If you're not, it could severely damage expensive equipment and cost you or your employer substantial money.

    Multimeter measurements on adjustable speed drives utilizing the new Fluke 87V DMM

    In the past, motor repair meant dealing with traditional three-phase motor failures that were largely the result of water, dust, grease, failed bearings, misaligned motor shafts, or just plain old age. But motor repair has changed in a big way with the introduction of electronically controlled motors, more commonly referred to as adjustable speed drives (ASDs).
