1hp irigation pump hooked up wrong
1hp irigation pump hooked up wrong
(OP)
I accidently hooked up a new motor to 110v supply and the motor was set to 220v.
I ran the motor for about 30 min or so then gave up. The next time I tried the motor cycled in and out a little. I then discovered my mistake and switched the motor to 110. Now it just makes an awful humming sound and smoke starts coming from it. I am wondering if there might be a way to save the motor????
Thanks for any help

Unless this is a very special and very expensive motor it will be cheaper to replace it than to rewind it.

I'm surprised your upstream protection ( fuse or breaker) didn't provide any trip to the circuit.

A much bigger problem is why it's not turning at all on proper voltage and then smoking. I believe your load is just too much for that motor. It actually ran on 240V but can not (ever) run on 120V (perhaps).
There are TWO possibilities.
1) The Start or Run or both capacitors (if it has them) where damaged by the 240V.
2) The motor does not have enough torque to get past the centrifugal switch and hence leaves the start winding engaged which will always start smoking in about 3 seconds and fry totally in about 10. Hence, your motor is undersized for the application.

I will try to get a picture. It is a 1hp a.o. Smith motor on a sta-right irrigation pump. It will work on either 220 or 110, comes from factory set to 220.... I hooked up to 110 supply and ran it for 30 min. it ran but I did not get any water up. Motor smelled a little hot but I blew it off to a new paint burning smell. Then next time I ran the pump trying to get the water up.. the motor ran but was cycling on and off a little like when a pressure switch is used. then it just started to hum and smoke.
I think I will try to put on a new capacitor and see if that works. If not then I'll replace the motor.
again
thanks for the help

Go 25 feet up and the water will come down and hit you most summer afternoons.
