(The motor draws high current when stalled and low current when running close to rated speed.) Motors are usually run at constant voltage. | |
Mar 27, 2020 at 21:42 | comment | added | ToucherOfRabbits | I didn't realize just how wasteful the parallel resistance idea was initially. What if, instead of a parallel resistor, I add a motor with a little fan? Just a crazy thought. I'd be afraid of the light flickering, but maybe there's a solution to that? | |
