Power Wheelchair Motor

I'm trying to motify a wheelchair to a power wheelchair, I got the motor but I dont know how to attach the motor to the wheel.

So if you or someone you know has dealt with this situation please let me know...thanks.

Most are driven by sprockets and chain. One sprocket on the axle of the wheelchair and the other on the motor. For the ratio you you have to do some calculations.

showing how i converted some $13 harbor freight wheels to work with 17mm keyslot motor shafts. For some reason with goofy video format doesnt have ...

I am looking for recommendations on what kind of power supply I need to use for testing DC motors I removed from old wheelchairs. They will be used for robotics projects but I need to test projects using a stable source of power (not batteries). If you have any experience in this and have any suggestions it would help.

Thanks
I am currently looking at this supply. Any issues with 3 amps instead of 5?
Batteries are not feasible at this stage.
I know there are lots of different choices out there, which is why I am asking for suggestions.

Take two old car automotive chargers and connect them in series. Don't use a newer one with fancy regulators or LEDs on the front.
A typical 24 motor in a wheel chair will draw more than 5 amps under load. You said you wanted a stable supply, so make some initial tests with an ammeter and them make sure the supply is good for at least two times the average load. The free running load will teach you very little.
Try using a 20 amp fuse from the hardware store for protection until you get he entire circuit going. Then a good bet is the circuit breakers used in Cars. JC Whitney has a very useful $10 ammeter that's used to test alternators, so you can tell how much load you are putting on the supply. Start with 10 gage wires. Electric wheelchairs typically go 8 mph max and have 12" dia pneumatic tires mounted directly to the output shaft of the gearbox.

Good links can be found at usfirst.org and ifirobotics.com, also for wheelchair oriented stuff, National Power Chair.

I want to make an off road electric wheelchair for my son I tried used electric wheelchair motors but they dont have the power to go up very much of an incline. I tried to change the gear ratio, it climbs a little better but its slower. It runs on a 24 volt system 2 twelve volt batteries.

well why not use a modified winch motor One for a atv would probably be enough.Keep the double batteries wired in series (for 12volts)for a longer run time.
I suggest upgrading to a chain drive and sprocket setup. and perhaps tires that have a wider stance.
You could also add a suspension to the seat(part) by either using a spring or air setup something like 4 4"bags on the corners of the seat could be inflate around 30 psi(seems about right) with a simple 12v compressor and a adjustable 1-100psi valve would give a soft ride over the bumps(and ruts).

goodluck
