Question : 24 volt power supply for testing old wheelchair motors?
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.

Answer:
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.

Question : Is there anyone who knows how to make modifications(fit in an engine to replace battery) to a power-wheelchair
I'm a disabled guy & plan to make some modifications to my power-wheelchair. Is there anyone who knows how to fit in a motorcycle engine or any kind of suitable engines into a power-wheelchair? I need to replace my battery as it keeps giving me problems which is quite unconvenient especially when I'm on the road.. & it's really really slow(slower than an average human walking speed).
Anyone with informations regarding the modifications will be a great help to me.
Thx in advance. =)
Answer:
They generally make motorized wheelchairs fairly weak on power so that you don't accidentally flip them over or run people down with them.
Plus you won't be able to use it indoors if you put a gasoline motor on it.
If you are just going to use it outside - your best bet would be to get the motor (and possibly some other drive train components) from a ride-on lawnmower (or just buy a ride-on lawnmower, and take the blades, etc. off of it).
Rigging it up is either a skill you have, or don't have - I can make just about anything work - but I would have to actually see the chair you have in order to point you in the right direction.
