I understand that the stepper motor offers great control and higher torque, but is usually spec on devices requiring bi-directional control. so I'm thinking that the additional flexibility it offers isn't really required here.Additionally it requires a reset to a zero, doesn't it?In this case, the motor turns (always) to the right and the cam lever controls position., so only motor speed (pot) control, low cost are real requirements.Could someone explain the difference between brushless dc motor and permanent magnet DC, or are they one and the same? If they are different, per your note below, I assume the brushless (with higher speed) would require some step down. I would really like this to be driver either direct or direct via a bevel gear with no reduction.
