Embodiment Construction
[0047] Such as Figure 13 , Figure 14 As shown, the inner stator of the motor with adjustable outer diameter includes stator core III, winding IV and bracket V.
[0048] Such as Figure 3-Figure 7 As shown, the stator core III is formed by overlapping and deforming a plurality of ring-shaped integrated stator core punches I. The initial shape of the stator core punch I is a flat ring, and finally unfolded into a ring shape. Each stator core punching piece I has a plurality of tooth pieces 1 and connecting body 2, each tooth piece 1 includes tooth crown 101, tooth body 102 and tooth root 103, connecting body 2 is connected with the bottom of the tooth root 103 of the adjacent tooth piece .
[0049] Tooth pieces 1 of multiple stator core punching pieces I are superimposed to form a unit tooth block 3 of stator core III. Each unit tooth block 3 has a tooth crown 301, a tooth body 302 and a tooth root 303, and the connecting body 2 is correspondingly superimposed. The connect...
