Motor Comparison Chart - Limits and Selection Information †

† These values should be viewed as guidelines only. They might not apply in all situations. Designers are responsible to ensure that motors are properly chosen for their intended application. EV Source LLC will not assume responsibility from damage arising from use of this general information.

* Indicated value is without a transmission, i.e. "direct-drive"

Motor Comparison Chart - Performance Characteristics

† Torque values in this column are extrapolations from actual measured data at lower currents. They are intended for reference only and not as actual performance data. The exception to this is the torque value shown for the WarP 13, which is from actual dyno testing.

* A careful review of the listed torque values would raise the question of why the TransWarP 7 shows nearly the same torque value as the ImPulse 9, a larger diameter motor. The ImPulse 9 has a very short armature stack (~4.5"). The 7" motor was designed to produce a lot of torque for it's size and it has a VERY long armature stack (~7.5"). The 7" motor (16.62") is also much longer than the ImPulse 9 (13.6"). The 7" motor produces the torque at a lower RPM than the ImPulse 9. This is true across all the motors we carry. As the motor size increases, the torque capability increases and the RPMs drop.
