24v motor 650w-750w

[whiteblade]

I want to use this motor on a project to make a 4 wheel mobility scooter for my dad who has (ms) and can only stand for ten minutes at anyone time.

The motor i want to use has come from a electric single seater golf buggy so should be strong enough to pull my dad along at walking speed.
The idea is to make the frame out out aluminium making it lighter than most mobility scooter on the market today.

Motor

24v 650w - 750w

110A

RPM: 3100

black and red wire motor power

Yellow & black wire electric brake + manual lever brake.

Now can anyone tell how to get the electric brake to work? the thin yellow & black wire.

Thanks

the brake unit is a 24V solenoid operated mechanical brake. it is NOT used to slow down the motor. it is used to lock the motor when the scooter is parked or stopped. it is to prevent the scooter from rolling or moving after it has come to a complete stop.

on my electric wheelchair you have to apply 24V to the brake wires to release the motor. i think that most are the same.

This is the most common way for wheelchair motors to work; I suspect the same of those golf cart motors (that have the brakes). Basically there's a solenoid coil in the black (usually plastic) endcap that pulls a metal engagement plate away from a square or hex shaped attachment to the driveshaft on that end of the motor, thus releasing the motor to spin freely.

On my CrazyBike2 I simply removed the solenoid and plate to save weight, since I was never going to use that part.

As for the frame, some of the mobility scooters I've seen have had aluminum frames with lightweight plastic body panels; usually the heavy part is the batteries, almost always SLA gel types, anywhere up to 120 pounds of them depending on the range expected of it.

But the stability of the scooter in turns is often dependent on that ballast, as the scooters are usually very narrow (to fit easily thru household doorways even at slight angles) and somewhat high seating positions, to enable reaching things from normal seated positions or even higher. Without that heavy bottom weight, a lot of scooters would possibly tip over when turning at their faster speeds (even given that that is usually 4 to 8 MPH).

BTW--that motor looks an awful lot like the one on CrazyBike2 right now, which is a 4pole PMDC brushed motor. Mine has a different (thinner) output shaft design, but the internal shaft is relatively thick, about as thick as that one looks compared to the housing. My motor also has similar ratings (except I dont' know the max amps it's designed to take--it *has* sustained ~150A for at least part of a second, during a failure of drivetrain mechanics).

How physically large is that motor of yours? Also, could you upload larger versions of those pictures? I'm curious now.
