    I want to have a go at rewiring an N gauge 3 segment armature. can any one help with a diagram of the windings. PLEASE

    eightyeightfan1 Now I'm AMP'd

    Wow!..Thats quite an undertaking.
    Never even really thought about rewinding an armature. I just replace the motor.
    Wish you the best of luck. Would like to hear your results though.

    Armature rewinding

    Use a low wattage soldering iron.... 15 watter. Check radio shack or an electronic supply or micromark.
    Slotcars are my other hobby.
    There is a slotcar forum and there are a few slotcar motor rebuilders that may give you some more help
    I do rebuild my slotcar motors.
    There is a forum site for slot cars
    Find out what size armature wire on that arm.
    Do plan to rebuild this motor?
    If so, remember how the magnets are installed.
    Care in pulling the pinoin gear of and how afr on the shaft its on.
    Remember what side each of the comm brushes came off. Good time to check them, if look poor, replace them.
    The part that the brushes fit into are called the hoods. Make sure they are not loose or look out of alignment.

    The arm, best to see how the winds unwrap to determine on they are winded on.
    The spacers, remember how many on each side of the stack, stack is the segments that the wire wind around. Also check for play, too much not good, too tight no good also.
    The arm should center within the magnets.
    Check the commutator on the arm that there is no movement. After rewinding assembly and get the motor to run, put a drop of acc between the winds and the comm.
    Before winding, check the comm for roughness, burr marks, can use either ultra fine sanding paper or very soft pink eraser, spin the arm in a drill low speed and polish the arm comm.

    Once you get the motor back together and working, break in at about 3 - 4 volts dc or low speed, not too low and not too fast for about 10 - 15 minutes.
    Lightly lube at the bearings.... a drop.
    I hope this will help you on rewinding.
