Copal DC Motor
I have salvaged DC Motor (Copal) from and old floppy disc drive. However I don't have any information on them. It is an LC-177B. I also need a control circuit for it. I am building an inductor winder for guitar pickups.
Regards Gary |

There will probably be two wires for power and ground, one for enable, which needs to be either +5 or grounded to turn it on, then another for tach output, and there may be yet another for selecting the speed since low and high density disks used different RPM. |

Thanks James. I believe you may have just solved the problem. That being my lack of knowledge of the workings of the motor. I still have the rest of the drive. I believe I can work out which lead is which from that. Regards Gary |
