Abstract:
A motor includes a stator comprising windings configured to be energized, and a rotor electromagnetically coupled to the stator and configured to turn relative thereto when the stator is energized. The motor also includes a motor controller configured to measure a speed at which the rotor turns, and energize said stator to generate a first torque output at the rotor when the measured speed is below a first threshold. The motor controller is also configured to energize the stator to generate a second torque output at the rotor when the measured speed is at least the first threshold, wherein the second torque output is greater than the first torque output.
