Abstract:
A brushless synchronous motor includes a rotor having a number n of embedded permanent magnets and being rotatable relative to a stator having a number of stator teeth provided with a three-phase stator winding, while forming an air gap. An angle between two adjacent permanent magnets is 360°/n where n>8, an angle between two adjacent stator teeth is 360°/n+2, and an inner contour of the stator facing the rotor has a curved structure with curvature valleys provided at ends of the stator teeth.
