Thread: Motor and Gearbox Pairing

    Motor and Gearbox Pairing

    Hello,

    I was wondering what factors to consider when sizing a motor and gearbox. Assuming I have two systems which both achieve the desired torque and speed, one is a larger motor with a smaller reduction, the other is a smaller motor with a larger reduction.

    Apart from the obvious size and cost, what are some comparisons I can make between the two? Will there be notable dynamic differences between the two?

    Thanks,
    Darrell

    Start with torque and RPM requirements which will define gearbox requirements then size motor appropriately.
    Tell me and I forget. Teach me and I remember. Involve me and I learn.

    Hi Kelly, thanks. I'm not picking a gearbox and motor from a catalog per sè, rather I'll be making these specifications myself.

    There is theoretically an unlimited number of combinations that could achieve a certain speed and torque.

    I am more curious about the less obvious differences when comparing two ends of the spectrum.

    a) larger slower motor with lower reduction
    b) smaller faster motor with higher reduction.

    Best Regards,
