Motor reversing
« on: July 18, 2010, 02:33:21 PM »
Hello, can anyone help, I have a single phase motor 240v AC 1/4hp that I want to use on my pillar drill. The problem I have is that its rotating in the wrong direction  (anticlockwise)   :scratch: and I was wondering if anyone on here as a solution to my problem? I have tried reversing the polarities but it still runs anticlockwise  :bang:

Cheers
Rob  :thumbup:

IF the motor can be reversed there will be a wiring chart usually on the motor or inside the wiring box for the motor. If you don't see that you probably have a single direction motor. Turn it around and mount it on the other side of the belt if possible is your only option.

I was going to say flip it 180º. May be the same thing Dan suggested.  :scratch:

take the ends off and swap them over so the shaft sticks out the other end

If it has a capacitor it can be reversed by reversing the connections to the starter windings,  it is a job for someone who can open it up and figure out how to do it.

Yep, same thing but you described it in a more elegant fashion.  :D

Thank you, for all you excellent suggestions  :thumbup: Mr Swift, I really must thank you for your wiring diagram that you posted, I followed it, and I'm pleased to say it worked a treat  :headbang: Pillar drill now spinning in the correct direction  :D I must admit, I was a bit nervous as I flicked the switch  :zap:

Thanks again Guys

I have a few modest talents. Knowing what I'm doing isn't one of them.
