Title:
AN ELECTRIC MOTOR WITH PLURAL STATOR COMPONENTS
Document Type and Number:
WIPO Patent Application WO/2015/087037
Kind Code:
A3
Abstract:
An electric motor apparatus comprising: a rotor; and a stator formed of at least two stator components, each of the at least two stator components having a substantially hollow cylindrical form. The rotor is mounted within the at least two stator components on a rotational mounting such that the rotor can rotate about a longitudinal central axis with respect to the stator. Each of the at least two stator components comprising at least two protrusions arranged at different circumferential points on an inner surface of the at least two stator components, each of the at least two protrusions having a winding mounted thereon; and control circuitry configured to generate control signals to control power supplied to the windings on each of the at least two stator components, such that power can be controlled to each of the at least two stator components independently of each other. The at least two stator components are mounted adjacent to each other along the longitudinal central axis and rotationally offset with respect to each other, such that the at least two protrusions on one of the at least two stator components are offset with respect to the at least two protrusions on an adjacently mounted one of the at least two stator components, such that a portion of each of the windings that extends beyond a longitudinal end of the protrusions on one of the at least two stator components fits within a gap between windings mounted on the adjacently mounted stator component.
