single phase shaded pole motor reversal question

Post by henryr »

My motor rotates in the wrong direction for my application and I've read this type of motor is non-reversible. However I've found some youtube videos that show the rotation can be reversed by removing the end caps, pulling out the rotor and reinstalling the rotor such that the shaft is at the opposite end of the motor and the end caps are also reinstalled on opposite ends of the motor. Is there any downside to this reversal process?

Thanks,

That should work fine.

I would hazard a guess it would run in the same direction but swapping the drive end gives you reverse.

Many posts and info on the web it seems these motors run very hot because of the shaded pole components. It also seems they require constant air flow so they don't overheat. Based on that I don't think they would be appropriate for a mini lathe.

I would think hard about using this on a mini lathe.

Better off with a dc motor..
Too many things going on to bother listing them.

I agree with Bill. Shaded pole motors have low starting torque and poor speed regulation.
