Need help wiring salvaged electric motor Answered


I have an electric motor I salvaged from a clothes dryer. I would like to add a three prong plug to it. However, I'm not experienced enough to read a schematic and I can't find any other tutorials that use the same motor.

It's from a 2014 Whirlpool Dryer. I need to know where to connect the black, white and green wires.

Any help is appreciated.

Earth connection is pretty obvious to see by the marking.
Leaves only 3 more to try for 2 wires, I suggest using a multimeter.

If you're referring to the green marker/brass/silver screw, I figure that's the earth. I have no multimeter, and couldn't read it if I did. LOL!

What I'm looking/hoping for is a simple explanation for which tabs to connect my live, neutral and earth (ground) wires to.

Maybe someone has done this with a very similar motor.

Thanks for the prompt reply!

But you do realise the motor is rated for 25A and would require a heavy duty outlet and more than a standard 16A circuit breaker?
At least if I am reading the text on the pic correctly...
Usually not the kind of thing you connect to a standard power cord.
And with no testing equippment nor knowledge how to use it I can only recommend to take it to someone who knows.
No point in you risking life or a fire by connecting unsuited cables or plugs to this beast.

Excellent point. However, my shop is wired correctly for higher amperages. Maybe I'll ask the electrician who wired my shop.

In that case it would be the best option.
The sparky can select the righ sized cable and if need be in a very flexible form in case you need to move the thing around a lot.
If you tell him upfront the motor is rated for 25ampere and to bring a suitable flexible cable of specified lenght and a plug the job won't take 20 minutes to finnish.
Can say if he would do it with the motor open like in the pics, safety you know, but that's a different topic.
Bonus for you is the peace of mind that everything is connected according to specs and the sparky might even let you know what you have to do/fix to prevent shortcuts on the contact points or how to enclose everything so your insurance is happy too.

The coffin was a "You must do it!!" thing.
My niece was quite a desperate fan at that time and her mum thought it is a good idea to tell her that the uncle can do all sorts of things with his new toy LOOOL
