ABSTRACT:
The permanent magnet brushless motor permits dynamic change of output characteristics by varying the positional relationships of rotor components, with respect to each other and with respect to the stator, to progressively effect field weakening with increasing speeds. The force required to impart the limited range of motion involved is transmitted to the rotor component by way of bearings and/or an actuation motor, and a helical guide path is used to great advantage for constraining such movement. The wide, dynamically adjustable motor output range of the motor effectively provides the equivalent of an efficient, continuously variable transmission. High torque at low speeds, and efficient, constant power output over a wide high speed range, uniquely adapt the motor for use as the prime mover for electric/hybrid vehicles.
