Sewdhull Posted January 20, 2024 Posted January 20, 2024 (edited) I was fiddling with my charger this morning, having owned it for maybe 10 years and I found it had a brushed motor power mode. You can set the voltage and the max amps, up to 5A. Useful I think for motor comparison and running in, if anyone does this. Do others have this setting? The option was in external function... What was interesting I thought was that the src high torque motor wouldn't start at 5A, but once helped ran at around 3A. Edited January 20, 2024 by Sewdhull

Sewdhull Posted January 20, 2024 Author Posted January 20, 2024 The ppl that run motors in tend to be car racers. They submerge the motors in water to do so, the bits come off in the water and it speeds things up and leaves everything shiny and clean.
Pseudotectonic Posted January 21, 2024 Posted January 21, 2024 I'm scared of water ruining the grease inside the bearings so i avoided that method altogether
Pseudotectonic Posted January 21, 2024 Posted January 21, 2024 nah don't wanna take the risk of getting water trapped inside the motor tower, plus I get to monitor the brushes while it runs so to get an idea how much time it takes for new brushes to seat with the commutator
