I was wondering if anyone has advice on wiring a new motor to my existing switch. I’ll include some photos.

Thanks for all of your help I have the motor up and running as a result. I did notice that the 1425 rpm motor is running close to the 1725 rpm original. I’ll keep an eye out for any smoke or overheating but at this point it seems fine. I’ll probably pick up another motor to keep around just in case. At least I will have no problem rewiring it. Thanks again for your help.?

Hi There,

?

I can see that I am late to the party.? I have a wiring

diagram for a Furnas drum switch that has the same

jumper configuration.? I'll pass it along for your con-

venience.

Good Luck!

Yes, your 50 hertz 1425 rpm motor will run at 1725-1750 on 60 hertz. I think your motor will have a centrifugal starter switch wired to the start capacitor. The problem with running 50 Hz motors on 60 Hz is that the centrifugal switch will cut out before the motor is up to speed (switching off at 1425 rpm while motor is heading for 1725 rpm). This would be a problem if the motor is heavily loaded on start up, but I don't think would be a problem on a 10L which usually would use a 1/2 HP motor.

The theoretical rpm on 60 hertz is 1800 rpm, but motor slip yields the 1725 you are seeing. The nameplate 50 hertz of 1425 rpm is 50/60 x 1800 = 1500 rpm theoretical, 1425 rpm with slip.
