Abstract
The present invention provides a method for modifying a stator tooth top arc of brushless DC motor, including: detecting motor parameters; determining an angle θ between initial slot axis and eccentric slot axis; determining a first arc by taking the rotating center of rotor as the center, and taking a first radius Ras the radius, where, the first arc intersects with eccentric slot axis at a first intersection point; determining a second arc by taking the first intersection point as the center, and taking a second radius R as the radius, wherein, the second arc intersects with eccentric slot axis at a second intersection point; determining a third arc of the first intersection point by taking the second intersection point as the center, and taking a radius of R as the radius, and modifying the stator tooth top arc according to the third arc to form a modified stator tooth top arc.
