Next job. Making the powerchair RELIABLE!
Stock powerchair motor couplings, on most powerchair motors, or rubber cush drives if you prefer, fail with monotonous regularity. As soon as you fit decent low resistance batteries (throw away those gels), fit decent wiring, and program the chair to turn, stop, and go.
I have a draw full of these failed ones. From 3 different motor manufacturers. It feels like a gearbox failure, but in reality its a £2 part... Most are similar. What happens is that suddenly you put some real torque through them. And the outside case splits, jams under load as it expands.
I fix these now BEFORE they can fail.
The problem: (Good one on the right...)
