Interesting, but rather large for a 3hp motor. At 220V and 1000-1500 RPM, it doesn't leave much opportunity to run higher voltage to get higher power at, say, 4000-5000 RPM such as typically is done with 48-72V forklift motors. That'd put you up near 1000V battery which is undesirable as well as making a controller rare. Better pass on this.
