Using a small treadmill DC motor?

[catmanjan]

Hello, I am wondering if anyone has tried converting a car to electric using a small (<3HP) treadmill motor

I have converted a few old Ajax pumps to solar using scrap treadmill motors - I am wondering if anyone has tried putting one of these into a car?

Of course I would expect the car would probably only go 20km/h, if at all, just wondering if anyone else has tried?

I guess the first question would be why?

treadmills don't have high loads to start with, a 3hp one would be unheard of (requiring a 15A plug for a start).

they would be okay as a belt drive to accessories (aircon pump, ps pump, alternator, etc)

Well I was thinking people may have tried because you can get them for free (people seem to give them away when the computers break but the DC motors have plenty of life left on the brushes)

I'm not sure if the ratings on the sides of the motors can be trusted but the ones I use claim to be 2.75hp series wound DC motors

They have a 19mm keyed shaft

They where made to JUST move a 120Kg person
but when they have 2000Kg of lead in there pockets.............. i have a feeling they would not do much but melt down
