Solderless Connections to DC Motor?

    I have a "GM3" DC gearmotor from www.hobbyengineering.com which has two
    metal tabs with holes in them for electrical connections.

    In order that I can reuse the motor, I'd like to make a solderless
    connection to it rather than soldering as usual.

    I'm considering using alligator clips or just "hooking" some jumper
    wire through the holes in the metal tabs; I think there should be a
    more elegant way though.

    Any feedback will be appreciated.

    Thank you.

    Tabs like that mate with a "quick disconnect" crimp-on connector.
    Measure the width of the tab and find a mating part. The tab
    width is the standard dimension for this class of connector.
    From the pictures, it looks like an 0.11" Faston female disconnect
    might fit. But measure. The proper mating connector will have
    a little dimple that lines up with the hole and locks the connector.

    Take a look at the engineering data for the connector here.

    then maybe one of the other AMP "Faston" terminals they stock?

    An Indian company we once used sourced their tabs and terminals from different
    suppliers. The dimensions weren't particularly well controlled to say the least
    ( never mind the quality of the spring material ! ).

    Some were indeed very "quick disconnect" !

  5. That's what I thought about a Maxon motor too. When I tried to disconnect
    it, the motor tab broke.

    A short 1" or so wire soldered to the motor terminal with a connector on
    the other end of the wire may be a good alternative, with a little epoxy on
    the motor terminal side to add a little strength.

  7. Why not solder fly leads to the motor and have your connections via them
    then you can reuse the motor by just using a compatible connector on your
    next project.
