Chosen Solution
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?
Hi, These two images are from the service manual for an Invacare P9000. It uses the same motor part number as what you have stated. Hopefully they will assist you in solving your problem.
