I have an auger that is triggered every 5 seconds for 4 seconds. It spins at 1 rpm. brushless 120 VAC at .5 amp. It can handle about 100 inch pounds of torque. I don't have the ability to change the programming on the motherboard. That would be too easy. lolI want to decrease the rpm in half when I want to without burning up the coils of the motor in the mean time. Could I put a dimmer switch in series with the motor until it puts out 60VAC? I just figured it might get stuck trying to push the load and burn up. It is an expensive little motor to experiment on.Any ideas is appreciated
Could I put a dimmer switch in series with the motor until it puts out 60VAC? it depends on the exact type of motor. universal or ac/dc motors can be speed controlled, but synchronous motors spin at a rate determined by the supply FREQUENCY so changing the voltage would do no good. Could I put a dimmer switch in series with the motor? no, dimmer switches produce spikes which would do your motor lots of no good, and produce catastrophic interference. And since its an inductive load you would also blow the dimmer.
