In other words, if motor is supplied with stall current for more than few seconds, it will get damaged by heat. So, one just needs to monitor the current going into the motor and it gets as high as 90% of stall, immediately disengage.
How can one use Hall effect sensor to measure movement. You thnik attach the magnet to the shaft and than measure Hall effect current/voltage?
What percentage of the stall current is optimum for continuous running of the motor?
