Problems solved by technology

Since the connection part of the punching sheet is very thin, it is easy to cause deformation and breakage of the punching sheet, which increases the production scrap rate
In addition, the laminated iron core also has the disadvantage of poor mechanical strength, and the inner circle of the stator is easily deformed due to external pressure, which in turn affects the operating performance of the motor.

Abstract

The invention provides a permanent magnet switch magnetic flux linkage motor comprising a stator iron core, a rotor iron core, armature windings and permanent magnets. The stator iron core comprises multiple stator grooves and stator teeth which are arranged between the adjacent two stator grooves. The stator teeth are provided with permanent magnet grooves used for placing the permanent magnets. The armature windings are arranged in the stator grooves. Magnetic separation holes are arranged on connecting parts of the permanent magnet grooves and the stator teeth. Magnetic separation bridges are substituted by the magnetic separation holes so that area of the connecting parts on the periphery of stator punching sheets is increased, and deformation in the process of assembling, testing and using stators can be reduced. Besides, the magnetic separation holes are additionally arranged in the internal diameters of the stator punching sheets to act as the connecting parts so that mechanical strength of the stators is further enhanced.
