Removing The Shaded Pole Of An Induction Motor

Removing the shaded poles of a microwave fan motor. The fan motor in this microwave oven is a single phase induction motor which employs the use of shaded poles for starting in the clockwise direction.
From the back of the microwave the fan is observed to be rotating the other direction i.e. anticlockwise.
Single phase induction motors are not self starting and in this experiment I will be removing the shorted winding and prove that this motor can rotate in the other direction.
This is an unlisted video of how to remove the winding.

Funny I just disassembled one yesterday for the purpose of using the magnetic flux plates as an anvil for pressing/pushing small parts in the 20-ton hydraulic shop press.
I did run a couple of weld beads along the outside of the plates to keep them together.

[@TheRetroShed]

Great explanation thanks. I used to play with one of these motors as a kid and always wondered what the small copper strap was for. :)

[@DominicGichane]

Thank you for your kind comment

[@carlossilva3122]

Good stuff! Does it use less power (once started) without the shaded pole?

[@sekyanzimarvin6974]

Thanks I liked how u explained

[@amanmittal4232]

Sir I have a small exhaust fan used in welding machine (which is basically a shaded pole motor fan), whose winding is burned now i dont want to rewind it for 220v configuration rather i want to run it on 12v or 24v ac how much number of turns per slot i should make..plz help

[@sl5311]

I have a small 1/100th .3 amp shaded pole motor (powers a small greenhouse inflation fan) that looks like a Fasco induction shaded pole motor, that locks up the rotor after I start it. I oiled the bearings and clean it and noticed that one of the copper shaded pole rings looks broken. The copper shaded pole rings are supposed to be complete circles, right? No breaks, right? Can I just cut them out like you did and start it by hand, like you did in this video?

[@musicphilebd9862]

Nice video friend. Are you an electrician?

[@salemslam5653]

Thanks my friend.

[@DominicGichane]

Thank you too

[@sogramomin5453]

Thanks, no one yet shown how to remove winding. but only you....

[@surendrakverma555]

Very good. Thanks 🙏🙏🙏🙏🙏

[@DominicGichane]

Thank you too

[@Crowley9393]

Ummm... Dude, you could have flipped the rotor & end pieces around if you wanted it to spin the other way. No need to remove the shaded poles.

[@mobmob5944]

Thats what i was gonna say lol. Was scanning thru the comments to see if someone already said it tho. Unless the 2 spade terminal contacts are on the side and for some reason its blocked by anything you are installing it in (which is not on this case) you could just solder a wire to the terminals and run it to where its not a problem to connect to a power supply connection

[@DominicGichane]

I'll definitely try this when I get my hands on another motor

[@uasserkamal2002]

Thanks alot sir

[@DominicGichane]

You're welcome

[@justcallmebill1061]

Hello
Can I use a label mark 220V 50Hzs shaded pole induction motor , in 220V 60Hzs
or
use a label mark 220V 60Hzs shaded pole induction motor , in 220V 50Hzs
thanks

[@kf5hcr176]

frequency sets the speed

[@sogramomin5453]

Even you should put putting back winding

[@M3a9m]

If I have same shaded pole motor which I'm not sure if its 110v or 220v, how do I find it out?

[@DominicGichane]

A shaded pole motor has a thick copper wire accross the core

[@Pelican_t]

If you want to figure out the voltage try measuring the resistance of the coil. Now this is an estimate so don't take this as 100% true but I have a 240VAC 50Hz motor and the coil resistance is 420Ω so by doing some division might get you your answer.

[@RealTamilHorror]

Any idea for increase rpm of this.?

[@DominicGichane]

Basically by varying the voltage applied. Jeremy Fielding has a very good explanation here ua-cam.com/video/JTlHNOaBnPI/v-deo.html

[@RealTamilHorror]

@@DominicGichane how many volts possible for it its 220v motor

[@DominicGichane]

@@RealTamilHorror The only true way to know is by using a variable transformer

[@mytechtrials]

Nice experience but you haven't shown how you removed windings.

[@DominicGichane]

Thanks. The windings were on a piece of the core that I hammered out. I still have the video file
somewhere and will upload it in an unlisted video. I will alert you when I do.

[@DominicGichane]

As promised here is the video ua-cam.com/video/fnKAp4aypyM/v-deo.html

[@sir.burbonburg7008]

It looks like the motor is weaker without the shorting windings. Is this true?

[@DominicGichane]

No. Generally shaded pole motors are very weak. That's why they are used for small tasks like rotating fans.

[@sir.burbonburg7008]

@@DominicGichane I removed the windings from my fan motor yesterday.
Although he could now start in any direction, he only had about 5% of the power.
So it is logical because the rotating field is almost no longer available.
I soldered a winding and it is now usable again and surprisingly now more stable with my TRIAC.
I know that these motors are weak but not sooo weak ;)
Thanks anyway.

[@vijaykanjwani]

My motor was gives sound so i pull it but after pull out My motor was not working so how can i repair it

[@DominicGichane]

You must have nicked the winding. The only solution is to get another motor because finding the winding is almost impossible

[@transformer889]

It is motor not moter

[@DominicGichane]

Rogor that :)
