ABSTRACT:
A precessional device having independent control of the output torque generated by the device and the oscillation race of the device is disclosed. The device comprises a rotor supported by an axle wherein the ends of the axle are supported by a circular race. The circular race is rotatable, and may be driven by, for example, a motor, thereby controlling the oscillation rate of the device independently of the output torque arising front the rotation rate of the rotor. The motor may be controlled by a control program that adjusts the rotation rate of the circular race to modify the shape of the resistance curve.
