115/230 Doerr motor set at 115V ..plugged into 230V

An unfortunate event.. I plugged in a 115/230 Doerr motor ( LR22132. model T63BXBYY1147) set at 115V into 230V.. resulting in the motor no longer working...

Does anyone have any info re: 1) is the motor repairable? 2) if it is repairable, how to troubleshoot - diagnose what parts need replacement..

Any help is appreciated...

Harry

Welcome. Don't know how such things happen, but on a tag, on the outside of the motor or inside the cover, should be a diagram showing the correct wiring for the desired voltage, so I would use that to check that it's wired properly and try again.

Hi, you may have just tripped a circuit breaker, how was it possible to plug a 120 volt motor into 240 volts source in the first place?

How long was it plugged in?
Did it smoke?
Other than the windings smoking, there are no parts inside an electric motor that would burn up if plugged in for less than a minute.

Somebody put the wrong end on the cord or didn't change the motor wiring and the cord end.

I doubt the motor will be good anymore but you can start by checking the capacitor microfarads to see if they are still good. If they are then I suspect the motor windings have burned up. If that is the case, you could still repair the motor by having it rewound but I suspect it will be cheaper to just replace the motor.

You should not have a 240V outlet wired for 120V plugs. For this exact reason.
There SHOULD be an overload / reset button somewhere on the motor, if it's not visible, you may have to loosen a screw and remove a sleeve on the back of the motor to access the reset button.
If there is no reset button, there should be a replaceable in-line fuse near the cord.

There is not usually a reset button and there is no fuse on a motor of that type.
There is a thermal overload that opens if the motor overheats and closes when it cools.
Most overloads are built into the motor and are not replaceable if damaged.

I would take the motor to a motor repair or rewinding shop and have them check it out. OR.......you could call the manufacturer for assistance. Doerr was acquired by Emerson around 1987 and Emerson Motor Company was acquired by Nidec Motor Corporation I believe in 2010. Nidec continues to lease the old Emerson Motor Technology Center on the Emerson Electric campus where the engineering is located. You could probably get some valuable information from an engineer there by calling 1-888-637-7333. OR....contact them from their website.
