Embodiment Construction
[0031] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0032] The permanent magnet linear motor with a stator of the present invention adopts a mixed structure of an arc shape and an inner ladder shape. Layer 2, permanent magnet mover secondary side 3. The stator armature primary side 1 includes a stator core 11, an armature winding 12 placed in a slot on the inner surface of the stator core 11, stator teeth 13 and stator end teeth 14; the stator teeth 13 on both sides of the slot adopt Arc-shaped structure; the secondary side 3 of the permanent magnet mover includes a permanent magnet mover core 32 and a permanent magnet 31 pasted on the surface of the mover core, and the surface-mounted permanent magnet 31 adopts a Halbach irregular permanent magnet array .
[0033] In the permanent magnet linear motor based on the mixed structure of the stator arc and the inner ladder type of the present invention, the stato...
