Stator for permanent magnet synchronous machine utilized during driving motor car, has segment comprising tooth region for receiving coil, where main axis of region includes angle greater than zero degree and less than forty five degrees

摘要

The stator (1) has a segment (2) comprising a yoke-forming floor area and a pole-forming tooth region for receiving a coil (9) of an electrical winding. A main inertia axis of the tooth region includes an angle with a cylinder axis (3) of the stator in axial direction, where the angle is greater than 0 degree and less than 45 degrees. The tooth region includes a tooth shaft and a tooth head, where the tooth shaft comprises parallelepipeds. The segment is formed from soft-magnetic composite material.
