AC 34/AC 35

The AC 35 motor is designed for use in utility and light automotive applications (up to 2250 lbs). It is capable of producing 63 horsepower at 2900 RPM while delivering 129 ft-lbs. of torque at 96 volts, and 650 amps(1238-7601). It is available in several different configurations depending on your needs.

In addition to the AC 35 motor we are producing a second version of the same motor size and calling it an AC 34. This motor was designed to extend the "knee" out further into the RPM range. So with the same 96 volt/650 amp controller(1238-7601), the torque reduces a bit down to 107 ft-lbs. of torque while the horsepower increases to 65 horsepower. All of these subtle changes and the knee extending out to 3800 RPM.

The motor identifications on this page have been changed to "AC 3X" to reflect the addition of the AC-34 into the AC-35 family.

The weight of this motor is around 85 pounds/38.5 Kg.
