Abstract
Electric motor cluster consisting of several stator sections each possessing a minimum of two salient pole projections, wound with power windings, and each section containing a single rotor. Each individual motor is angularly displaced one from the other, while mounted within a common housing, and geared together such that each motor section contributes to the rotation of a common output shaft. Each motor comprises at least one stator and one rotor section, such that each rotor section is associated with a specific stator section. The lateral axis of each rotor section is disposed at an oblique angle with respect to the axis of the shaft for that particular motor.
Claims6
A motor cluster comprising:
- a plurality of constant air gap reluctance motor sections, each having a rotor and a stator, and each motor section driving a single output shaft;
- an output shaft position transducer;
- and
- a motor controller,
- wherein said motors are physically connected to said single output shaft such that the angular relationship between the rotor and stator of a first of said motor section is different than the angular relationship between the rotor and stator of a second of said motors;
- and wherein said motor controller applies electrical power to said stators to rotate said rotors and said single output shaft via a reduction gear assembly.
