You might want to look at the motors from http://motenergy.com. I used
their ME1007 to repower the snowblower on my Electric Ox and it has
served me very well. They have a bunch of 4.8kW motors running at
3000-3600rpm, which matches your needs. They would certainly be
sufficient, maybe overkill, to replace a 8HP gas motor.
I have no controller on my Ox. There is just a contactor. Not exactly
what I'd recommend, but it gets the job done. Make sure your batteries
are up to the initial current if you go this way. When the contactor is
off the NC contacts short the motor windings through a resistor made of
something like 50 feet of 16 AWG wire. This brings my snowblower to
a stop in a second or so.
