Permanent magnet generator with stator inclined grooves and inclined groove realization method of permanent magnet generator

The invention discloses a permanent magnet generator with stator inclined grooves and an inclined groove realization method of the permanent magnet generator. The permanent magnet generator comprises a generator stator, wherein the stator comprises a stator casing and a stator iron core punching sheet and also comprises a plurality of convex strips, the convex strips are arranged on the inner wall of the stator casing according to a certain inclination, clamp grooves used for being clamped with the convex strips are arranged at the back side of the yoke part of the stator iron core punching sheet, the stator iron core punching sheets are overlapped onto the convex strips in a laminated way through the clamp grooves, and in addition, the clamp grooves have the same inclination as the inclination of the stator inclined grooves and the installation inclination of the convex strips after the lamination. The stator inclined grooves of the permanent magnet generator can be realized, the tooth groove torque is effectively reduced, meanwhile, the harmonic waves are reduced, in addition, few toolings are required by the stator inclined groove realization method, the cost is low, and the process is simple.
