Testing Small Electric Motors

If the meter readout indicates 0 resistance the capacitor is shorted out and needs to be replaced.

Testing small electric motors.

They are near the back and have two colored wires. Set your dmm to the ohms function and touch the probes to the terminals on the capacitor. Many electric motor failures are caused by bearing failures. You need to check if electricity is getting to the motor.

Find the two small metal terminals on the electric motor. Bearings are located at both ends of the motor which are sometimes called bell housings or end bells. Test the capacitor remove one of the wires from the capacitor to test the resistance of the start induction run motor. 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. Small universal motors as for portable electric drills may contain extensive circuitry including a switch and brushes. Usually red and black attached to them. Turn on the power unit that supplies electricity to the electric motor.

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 coloured wires. 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. You can do it by multimeter with small manual power generator.

Usually red and black attached to them. The bearings allow the shaft or rotor assembly to turn freely and smoothly in the frame. Europe standard at least. Test for direct shorts in the motor s power windings in induction non brush type motors.

Each of the sets of windings should read about the same ohms value. Begin to check the bearings of the motor. I would like to fulfill more at least with one important point about testing of motors insulation. When an electric motor is broken one suspect is the fiel coild of the motor stator.

Find the two small metal terminals on the electric motor. You need to check if electricity is getting to the motor.
