dc motors
Hi: Can anyone tell me why my 24volt dc motor which I just got rebuilt will only work on 12 volts and immediatly overheats and stops with 24 volts? Thanks, Royal

You broke it? If you had somebody else rebuild it for you, they are probably the best people to answer your question.

That is why I am asking here, he says it works on 12 volt so should work on 24 volt. It's 25 years old and needed rewound presumably from age and heat.

Ah, "he" says it works on 12 volt so should work on 24 volt. Maybe this is the problem. If the motor was originally running @ 24V and now it doesn't then the shop hasn't rebuilt it correctly?

. The motor may have been rewound for 12V. . The motor leads may need to be configured for 24V operation.

Are you implying the lead wire to the commentator or brushes?I suspect he may have used a larger size wire on the rewind. Would that do it?

. Some motors will have multiple coils. When wired in parallel, they work at a lower voltage. In series for higher voltage. This may only apply to AC motors - I don't have much experience with DC motors.

Who rebuilt this and why? What sort of motor is it etc? L

A small motor shop. It runs a short duty hydraulic pump for cylinders. 15amp max no load.
