How do I troubleshoot and rebuild these motors?
I have two motors part numbers 1057300 and 1057301 from an invacare motorized wheelchair that I wish to use in a robotics project. The stator turns easily, but barely runs when energized with a 24 VDC power supply. I have removed the electric brake. The motor hums when energized but barely moves. I suspect it could require new brushes - how do I trouble shoot this DC motor and if required, how do I know if it is worth rebuilding and how do I go about doing this?
Questa è una buona domanda?

@rleaker bad brushes would not cause the motor to turn slowly. Are those still connected to the gearbox? Post some images of those motors with your question so we can see what you see. Use this guide Aggiungere immagini ad una domanda for that
