    Default Servo motor identification.

    I have what seem to be servo motors. There are no stickers on the outside of the motors for identifying. I can identify is a Sumtak encoder of some sort. The connector seems to be a latch type. Thank you.

    Looks custom industrial from the likes of Omron or Phoenix.
    Motor looks pretty big.

    I envisage you having to take them off and use an alternative.

    They appear to be BLDC, if so the encoder may have commutation tracks on them, as well as the usual quadrature tracks?

    DON'T MOVE THE "ENCODER". If you do, it could cost you more than it's worth to have it realigned, for proper commutation.

    Definately, dont move whatever it is. They are BLDC or "AC" servo's almost certainly, but without the MFG. spec.s, you will have a hard time trying to use them. There is no identification on the motor case? Bummer.

    Simple to do, but you need a double beam 'scope in order to align it easily.
    I have added a few to motors that either had failed or didn't have one in the first place.
    I replaced a few on Fanuc motors, which have a odd-ball, proprietary method.

    Hi,
    even if you can identify the servos you have a problem trying to get compatible drives.

    Argon drives by Granite Devices for instance are servo drives made to accommodate a wide range of servo motors, but they cost over $400. Even then there is scope for
    mismatch between an unknown servo and an Argon drive.

    A brand new 750W Delta B2 series AC servo, drive and cable kit cost $435.......everything matches perfectly, no mess, no shagging around.
