Speed control for hoist?
Hello all this is too fast for the requirement. Lifting a very expensive 350 lb film projector and need more finesse. There is a switch attached to the trip arm, if I toggle that switch fast by hand on/off I can get some PWM that kind of works, but it is also turning the brake on and off at the same time which is very loud. A worst case is connecting some optofet to the switch and setting some frequency maybe with P1 to find a good rate. I haven’t taken it apart yet to see if there is an access to control the motor separately by chopping it and not chop the brake.
PS. This only runs once or twice a year for service. I have some built in gearing with the cable system but not enough. I want 50% speed.
