My team uses a transmission driven winch to hang, but it’s performance has gone down for some reason, and we are trying to diagnose it. Is it possible that repeated stalling or other high load on a motor would make it stall more easily? This winch system has stalled many times, due to rope jamming and dead batteries, many times.
I checked, and all the motors do spin when the power is turned on, but replacing all the motors means all 6 of our drivetrain motors, and our 2 lift motors. Is there an easy way to test our motors before we spend $120 on new motors?
Not sure about if it leads to general wear though.
These motors don’t have an especially high lifetime. You could create a bench test of using a pulley to lift a weight (but not too much weight). It’s a nice controlled test but you will have to pop off the motors to verify their strength against each other.
Log your results to find the best motors of the bunch.
Take the motors apart, and look at all the electronics on the board with the motor (resistor and capacitor). see if either looks discolored, melted, scorched etc. if this is true, you must replace (of ask karthik if you can fix these things with desoldering and replacing). if these all look fine, try probing around and testing with a multi-meter, and if you find anything abnormal compared to a new motor, replace it. If this does not reveal anything wrong, ask jpearman , he knows about everything electronic.
I would be very careful before probing random points with a multimeter without a wiring diagram or at least an idea what to check. You don’t want to short something or damage the electronics by checking the wrong points.
