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?
Is this a good question?
