Why do stepper motors waste the most energy when not being used?

    Hi:


    My friend told me that stepper motors use the most power when not being used, is it true? if so, why?


    thank you

    Nope, not true. There is a difference between "holding" and "off". Can you do a little reading about stepper motors and tell us what that difference is?
