Interesting to know what the projected lifetime use of the motor was.


The Chiaphua motors are similar to starter motors - they are designed for infrequent but hard use lifting a trailer - maybe two minutes a day.

Running them under load (even low) for hours is certainly not a use the designer intended. The people who build Battlebots don't use automotive starter motors for this reason. Also note how fast you can run down an automotive battery by cranking a car that won't start.

Also running them at ten volts (Though a PWM?) might cause a heat problem.

So Dave - like the patient who asked the Doctor about "my arm hurts when I do this......"

Dr. Bot says: "Don't do that."
