Repairing a motor
I have a machine with an electric motor in it. We asked a bit too much of it
and during a job it laboured and ground to a halt. Now when we start it up it spins slowly and grinds to a halt after a few seconds. It can be turned manually with ease. Has something likely burned out within? Is a repair likely? If so am I looking at a rewinding company? Any input appreciated. Rick |

Rick It would sound like the windings or bushings are burnt out - I would think a re-windng company could tell you if it's the windings. |

You'll probably get a new one for less than the cost of a re-wind. -- *Black holes are where God divided by zero * Dave Plowman London SW To e-mail, change noise into sound. |

Does it smell If so am I looking at a rewinding company? I think you are prolly looking at a monitor Any input appreciated. You haven't really given enough info to make an educated reply -- geoff |

Look for any sign of one or more bars of the commutator having burn marks, or chunks out of one edge, or being loose or missing. These are all bad news, and point to an armature fault, but it could just be worn brushes. -- Kevin Poole **Use current month and year to reply (e.g. )*** |

Whereas poor brush contact means it runs..intermittently,and badly. |
