how to test 3 phase motor with multimeter

Let's learn how to test 3 phase motor with a multimeter
were are testing the following
1) Continuity
disconnect the motor from power and ensure that all the leads are not connecting to each other in the terminal box, test the continuity between each coil contact (U1 U2, V1 V2 and W1 W2) and make sure that there is continuity. if there is no continuity then probably your motor is burnt.
2) Short circuit test
We test short circuit between coils for Example testing between U1 and V1 and so on. There must know continuity between coils if all the 6 leads are out. ( the only exception is when the motor has been connected internally either in star or delta).
3) Resistance
While testing continuity ensures that you record the reading, the reading is determined by the resistance of the coil. The reading between each coil should be the same or the difference should minor.

Very gorgeous illustrations, simplifying the lessons, thank you brother, please don’t stop your excellent work

[joser]

It’s one of the simplest videos I ever seen to explain motor troubleshooting thanks brother !

[dickyboy]

Really good clear Instructions, found 2 broken windings out of the 3. Thank you

[laurentianvmx]

We have a bad compressor motor, this video will be useful for testing thank-you !

Very illustrative teacher, teaches very patiently. Very good.

Great job! But please note those test are basic without a megger. Insulation resistance test or integrity are very critical, hence, can only be achieved by visual inspection and using a megger 🙏🏽….

Good clear video. Worth noting that you are only testing with the small voltage from the meter. When checking for faults to earth ideally use a Megger which generates a higher voltage and will expose faults not shown on a multimeter.
