    Hi everyone,

    I have a Dunkermotoren DC motor with Gearbox and Encoder (it's second hand) with following characteristics:

    GearBox:
    nr 88850 01206
    36:1
    Mzul 80 Ncm

    Motor:
    G30 2 42/94
    88615 01500
    12V 0.60A
    2900 UPM

    Encoder:
    88710 04629
    01 22

    I don't know how to work with it. I wanna make it move 90degrees by pushing a button and then by pushing another bottun turn it back to 0degree (Poisition Controlling).
    I have no idea about it. could you please help me ASAP?
    Thanks!

    I think it will be difficult to control the motor so that the gearbox output shaft rotates only 90°. The gearbox ratio appears to be 36:1, which means the motor itself would have to rotate only 9 revs. So as soon as you start it up you will have to turn it off again. Inertia means that without sophisticated control (including perhaps dynamic braking) it will over-run.

    You would need some sort of controller/PLC etc. An encoder only gives positional feedback, you need a 5V connection from the encoder to the controller, you could get a unit from Dunker, but it tends to be more expensive than if you go with brushless motors with a built-in controller.
