3 Steps - How to check a motor only with a multimeter?

Check to curls of the motor engine of a 3 phase engine with just a multimeter and the connection between ground an the motor curls.

Significant improvement can be made utilising a circuit diagram of the windings and ground to illustrate the tests. It would very much aid in understanding the practical tests.

Nice lesson. Also good to remind people of the danger so we do not get complacent. Thanks Michael

I had to watch this video because returning to college we will doing this...now i have an understanding thank you so much this helped alot😅❤.

[@pistolcrossbow]

Thanks for this video :D It realy helped me out. I got my motor running now.

[@user-wz6pr5kn7d]

And thank you for informing us about danger hazards

[@tehking111]

You should really use insulation resistance test between earth and phase at double the working voltage. That way you get an actual reading instead open loop. Same for phase to phase. I don't know what the range is on your meter but if it only goes to like 100k ohms then you might weak short and not detect it. A fail is less than 1M ohm. Also worth noting if you put a star bar in, you can phase to phase test while checking balance by going u1 to v1, v1 to w1, w1 to u1.

Thank you - great video!

Resistor Widerstand (Das Ding an sich)
Resistance ist der Widerstand (Wert den du ausdrücken möchtest)

[@hachimankmd5843]

Sorry to break it to you but that's a big NO. You have to disconnect your coils and the power cable before proceeding with measurements.

Now i am lost lol I am a level 2 student 😢and we will be testing our motors returning on the 17 July now I am lost😅

Ich 😊

[@user-wz6pr5kn7d]

I do because it is easier for me to understand and I loved your 1st video so much easier nd understanding 😅

[@whynot9068]

What makes this dangerous? It doesnt look like the motor is receiving volts.

[@fearlessreview]

Precaution for someone t/s on unit installed lol you never know

[@christophercolumbus8944]

is this three phase motor. ?

[@ralfbrauckmann9751]

Vielleicht sollte noch darauf hin gewiesen werden die Stern bzw Dreieck Brücken vor den Messungen zu entfernen :-)

[@Nico_jo]

Welches Multimeter hast du? :-)

[@TheJimbobjimmy]

Isn’t that resistance quite high?

[@choohong1035]

Smaller motor usually has higher ohm, and bigger motor has smaller ohm

[@christophercolumbus8944]

@@choohong1035 hey do you know why a motor stops working after a few seconds of power? ? what could be the issue?

[@choohong1035]

@@christophercolumbus8944 motor run by contactor or vfd? Or you should try check motor ohm, running motor amp if possible, or bearing problem maybe?

[@user-wz6pr5kn7d]

Starting winding is the one with a higher resistance am i right😅?

[@leonard3115]

Good, aber why 'infinity'? This is not accurate, oder?

In der Reihenfolge?

[@akramkadhim9055]

Resistance check between the two screws??? For what? I don't think this measurement is important or necessary

[@Teknopottu]

He is checking the resistance of the windings. If they are far off/no resistance, winding can be shorted or broken.
He is also checking for the resistances between the three windings. If they have even some resistance in between, the can be shorted and/or broken. Each winding has to be separate from each other and from the ground.
The star/delta connections between windings have to be removed for this to work, he forgot to mention it.
Replying to an old comment but hopefully this helps.

[@bengunn3698]

@Akram He is checking between the earth terminal in the motor connection box and the frame of the motor to ensure there is electrical continuity , zero ohms. This is to make sure that when you connect the earth wire to the earth terminal you are earthing( grounding) ALL of the motor frame , not just the screw.

[@christianwareham5164]

Bad learning video. Your going through each test but not explaining. Just w1 w2 infinity lol terrible.

[@At-Imperial-Walker]

Horrible...no rhyme or reason...

[@gnaflethegarthok3074]

Annoying accent

[@TheCanciller]

You have no idea about electricity. Stop it buddy os dangerous!!!
