Permanent Magnet Motor
The Et-R:
represents the highest power/weight/dollar available on the market for brush PM motors. Designed and built by the same team that brought us the original E-tek motor. 3 lbs heavier, this radial motor can do 125 amps at 48 volts continuously and runs in either direction. This is ideally suited for 24-72 volts. Works with Alltrax and other PM controllers. Great for electrathons, motorcycles, and go-carts.
