Finally! What so many builders have been waiting for! This is a bolt-in replacement for the orginal Etek motor. The E-tek-R has the highest power/weight/dollar ratio available on the market for brushed PM motors.
Designed and built by the same team that brought us the original E-tek motor.
Slightly heavier than the original Etek, this radial motor can do 150 amps at 48 volts continuous
and runs in either direction. This motor is ideally suited for 24-72 Volt
DC drive systems. Works with our AX2550 or any other PM motor controller that can handle the massive current this motor is capable of pulling. Great
for Electrathons , Motorcycles, go-karts, ride on trains, boats, or robots.
