I need some help trying to pick a motor and controller (possibly VFD) for a winder application. It is going to use a foot-pedal input to control speed but the troubling part of this is the wide range of speed that they will run, which is 1-55rpm. We'll obviously need to incorporate a gearbox to get our motor to that range, but using an AC motor with a VFD means that we would have to run this at 1Hz some of the time, which would produce a bunch of heat. What are some other options out there (preferably AB) that wouldn't produce that kind of heat when running that slow?
