    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.
    also need a control circuit for it. I am building an inductor winde
    for guitar pickups.

    www.scientificsurplus.com sells that motor. Maybe you could email them
    for a spec on it.

    Do you still have the rest of the drive? Apply power and measure which
    pins to the motor are +5v and ground. 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.
