ABSTRACT:
Kinetic energy of a rotor is substantially prevented from exceeding a predetermined amount of kinetic energy by determining a first kinetic energy of the rotor spinning at a first rotational velocity and determining whether the first kinetic energy exceeds the predetermined amount of kinetic energy. In addition, torque being applied to the rotor is modulated in response to the first kinetic energy exceeding the predetermined amount of kinetic energy. In this manner, the rotor is spun at a relatively slower rotational velocity than the first rotational velocity.
