I have small a 24v dc gear motor that needs to run at a certain speed and full torque at times, performing a job of winding tape on a spool, but I want to be able to intermittently limit the torque when a switch is triggered. It may be drawing 24v 1A at times and I would like to limit it to 24v 200ma when the switch is engaged. I figure I would just have the switch cut off the direct line to the power supply and engage a current limiting circuit of some kind. I'm not well educated in electronics so please be patient with me... but I gather I could just use a resistor of a certain value to limit the current... is there a better way to do this, and what would the downside of this be?
Thanks,
Lars
