Abstract
1 / 1 ABSTRACT Brushless Direct Current Electric Motor and Electric Power Steering System A brushless direct current electric motor includes a first sub-motor (20) and a second sub-motor (30). The first sub-motor and the second sub-motor share a common rotor 5 (40), and each comprises an independent stator. The stators of each sub-motor comprises a plurality of teeth (T, Tâ) and a plurality of windings (C, Câ). The teeth of the first sub-motor and the teeth of the second sub-motor are interleavingly arranged in a circumferential direction or arranged side by side in an axial direction. The first sub-motor and the second sub-motor are configured to cooperatively work as a single 10 electric motor to output a normal power. When one of the sub-motors breaks down, the other sub-motor can be operated independently to enhance reliability and safety of the brushless direct current electric motor. 15 Figure 2
