I doubt you will find a 12VDC motor over 1HP. www.surpluscCenter.com has
2HP 24VDC motors that draw 72 amps ad full load for $200. You might also
look at old automotive starter motors. Not sure of the HP but they are very
popular for barstool racing in the 12V classes.


Every car that has a starter motor in it has a 12 volt motor that has a
rating way higher than a simgle horsepower......

Most car starters pull way over 100 amps when cranking the engine....
Assuming your starter draws 100 amps at 12 volts = 1200 watts.

The last time I checked the horsepower was supposed to be something like
762 Watts....


I rest my case.


Mind you they arn't rated for long term running... tending to overheat
rather quickly!
