Title:
BRUSHLESS MOTOR AND SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/165012
Kind Code:
A1
Abstract:
A brushless motor controller system includes a brushless motor (201) which further contains a rotor (24) and a stator (22), a plurality of independent motor controllers (203), a plurality of batteries (204), and a plurality of battery chargers (205). The stator (22) of the brushless motor (201) has a plurality of salient poles (32). A plurality of coils are wound on the salient poles (32) such that on each of the salient poles (32) there is wound different groups of windings electrically isolated from each other. The plurality of independent motor controllers (203) each corresponds and is electrically connected to one of the groups of windings on one of the salient poles (32) of the brushless motor (201). The plurality of batteries (204) each is connected to a corresponding one of the independent motor controllers (203) to provide electrical power thereto. The plurality of battery chargers (205) each is connected to a corresponding one of the batteries (204). The plurality of independent motor controllers (203) each is adapted to power and control a corresponding one of the groups of coils on one of the salient poles (32) in the brushless motor (201) independently. The brushless motor controller system utilizes distributed motor controllers (203), batteries (204) and chargers (205) for brushless DC motor (201) which provides not only flexibility in motor output control but also redundancies of the controlling system making it more robust.
