Torque — Figure 4 shows the torque-speed curve for rating purposes. Figure 5 shows the torque capability for a TEFC induction motor versus speed. As the speed is reduced from rated, the fan provides ...

All types control speed by varying current frequency, but one subtype — flux vector drives — uses current-switching techniques to control motor torque as well.

The Equinox EV didn't need more performance per se, which is why that induction motor only adds 75 horsepower and 97 lb-ft of torque over the front-wheel drive model.
