(stator)
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, stator 100 has cricoid stator core 110 and is wound in the stator core
110 armature coil 140.Stator core 110 includes the magnetism for being formed as the circular high magnetic permeability concentric with rotary shaft 1C
Material.
Stator core 110 includes cricoid stator yoke 120 and is set to the stator yoke at regular intervals in the circumferential
120 multiple stator tooths 130.The section of stator yoke 120 is formed as round or oblong cross sectional shape.
Stator tooth 130 is prominent from the surface of stator yoke 120, appears as from the axial direction of rotating electric machine 1 trapezoidal, also, revolves
The circumferential section of rotating motor 1 is formed as rectangular shape.12 stator tooths 130 are set to stator magnet at regular intervals in the circumferential
Yoke 120.
Specifically, stator tooth 130 has the 1st stator tooth 131, the 2nd stator tooth 132 and the 3rd stator tooth 133.
