Testing Small Electric Motors

Bearings are located at both ends of the motor which are sometimes called bell housings or end bells.

Testing small electric motors.

In the ohmmeter mode connect the meter to the plug and monitor the resistance as you wiggle the cord where it enters the enclosure. Test for direct shorts in the motor s power windings in induction non brush type motors. If the meter readout indicates 0 resistance the capacitor is shorted out and needs to be replaced. You need to check if electricity is getting to the motor.

Europe standard at least. Usually red and black attached to them. Find the two small metal terminals on the electric motor. The test may be non destructive for in service equipment or prolonged at elevated voltage to test prototypes to the point of destruction.

Usually red and black attached to them. Begin to check the bearings of the motor. When an electric motor is broken one suspect is the fiel coild of the motor stator. Keep the multi meter set for 30 000 ohms and touch one test lead to one terminal and the other to another terminal.

They are near the back and have two colored wires. They are near the back and have two coloured wires. Test the capacitor remove one of the wires from the capacitor to test the resistance of the start induction run motor. The bearings allow the shaft or rotor assembly to turn freely and smoothly in the frame.

Many electric motor failures are caused by bearing failures. You can do it by multimeter with small manual power generator. I would like to fulfill more at least with one important point about testing of motors insulation. Small universal motors as for portable electric drills may contain extensive circuitry including a switch and brushes.

Find the two small metal terminals on the electric motor. This test may take place on installed or on the reel cable tools appliances transformers power distribution subsystems capacitors motors and any type of electrical equipment or wiring. Motors in factory producer have to be checked phase to ground 2 un 1000v according en 60 034 1 acc. In this video we show different tests balancing test continuity coil.

You need to check if electricity is getting to the motor. Turn on the power unit that supplies electricity to the electric motor.
