DIY Electronic Controlled Motorized Wheelchair - Question

Hi,

I recently stumbled upon the DIY wheelchair gam3t3ch created ( DIY Electronic Controlled Motorized Wheelchair -- Episode 550 ), I loved the idea and wanted to create something similar. I am hoping to make the wheelchair a bit faster/stronger. I was wondering if you know of any motors and motor drivers that can help me out. I am looking for a little more torque and speed within $100. I am using an Arduino for this. Please let me know if you know any!

Thanks!

I seem to recall a number of makers using wheelchair motors in their projects because they are small, high torque and easy to get hold of, so perhaps start looking there.

Other places to look at might be e-bike parts and e-scooter parts as they are primarily designed to move people around so should already be in the right ball park.

good point. I believe the ebikes are DC brushless motors with torque regulation, maybe not the best for a beginner https://bikexchange.com/electric-bike-motors-guide/. I have an ebike, natively it is a torque provider, doesnt care about speed at all,

Wiper motors are a favorite for some folks.

Used/trashed wheelchair and mobility scooters motors are a possibility. One easy way to make them go faster and produce more torque is to overvolt them by adding another battery in series. It fun as an experiment, not great on the drive train :-) I'd expect the motor insulation could take the volts, but not the heat of wheelchair drag racing. Stall current could be a problem. Adding batteries and buying motors blow the budget pretty fast.

Motors from manual handling equipment might be another potential source. A small motorised pallet jack will usually be able to move at a walking pace while carrying a load much heavier than a person.

As well as windscreen wiper motors there are also cordless electric drill motors.
