    Can anyone help?

    I have a 1/4 hp ac motor that I am looking to make into a drum sander


    so the motor that I have has eight wires. The diagram is as shows

    Purple ------------------ ung'd line
    brown -------\ |
    \ |
    red ---------+-------- |
    / |---------low voltage line (110 side)
    orange -------/ | 110/220
    yellow -------\ |
    \ |
    black ---------+--------------

    green with stripe ------ ground

    It says on the label this is for cw direction and if switch the black
    and the red wire I get ccw direction. (or vice versa I forget which)

    I bought a Double Pole Double Throw three position toggle switch
    (on-off-on) but I just cannot figure out the proper wiring. I want it
    so that I have cw on one side of the toggle - center being off and ccw
    on the other side of the toggle. Can this be done? - If so - cna
    someone tell me how to wire it. If not - is it the switch or is it that
    I cannot do what I want with this motor. I guess I can always just use
    one direction but it would be nice if I can reverse it.

    Thanks in advance,

    Hi Rich,

    Thanks for the info. I still do not get it though

    There are six posts on the switch

    3 wires on the cord (i know green goes to ground)

    That leaves 7 wires to be attached to the switch. Where do I put those.

    I realize that I probably have to keep

    brown and orange together

    yellow and white together

    do I use the purple ungrounded wire at all?

    If I were to look at the posts

    1----2 on cw
    | |
    | |
    3 4 off
    | |
    | |
    5----6 on ccw

    what gets attached where.

    Thanks again -

    If the diagram that you gave in your first post is accurate, and the
    motor runs (in one direction) then leave them the way they are. According
    to your original post, only the black and red needed to be swapped to
    reverse the motor.
    I've replaced my designators with your numbers:

    I've done the switch diagram in the way a standard schematic
    is done. For each switch, there are three positions:

    On Off On
    o 1,2 o 1,2 o 1,2
    o o 3,4 o---o 3,4 o o 3,4
    o 5,6 o 5,6 o 5,6

    Interpose this between wherever the red and black are coming
    from, and the point where they attach. Connect the black wire
    to 1 and 6, and connect 3 to the terminal block on the motor.
    Connect the red wire to 2 and 5, and connect 4 to the terminal
    block on the motor.

    But this is all assuming that the rest of the wires don't
    need to be changed _at all_ - if that's not the case, then
    we need more information.

    Good Luck!
