Hi there, I have been asked to make up a very simple, yet efffective load detection circuit for a motor, 12/24v DC, the motor extends and is timed to how long it is running for, but the resistance against this motor, sometimes alters the distance it extends.
So i though, the motor has to come to rest and its home and fully extended stops.
If the motor is prevented from moving, it will then increase the current requirement.
if this could then be detected, the timing feature can be bypassed.
Any ideas on how this could be achieved? i had the though of a low ohm resistor inbetween the supply and motor, and messuring the difference on either side. but sorta got stumped at how to use this.
Thanks.
Chris.
