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...

Abstract

The invention discloses a motor inner stator with adjustable outer diameter, which is characterized in that a stator iron core is formed by overlapping a plurality of stator iron core stamping pieces in annular integral structures, tooth pieces of the stator iron core stamping pieces are correspondingly overlapped to form unit tooth blocks of the stator iron core, connecting bodies of the stator iron core stamping pieces are correspondingly overlapped to form connecting parts among the unit tooth blocks, the tooth root part of each unit tooth block forms a main yoke part of the stator iron core, each connecting part is bent towards the circle center of the stator iron core and is in an ear shape so as to form a secondary yoke part, the edge of a stator bracket corresponds to the tooth root of each unit tooth block and forms a through slot with each connecting part, a plurality of limiting supporting bosses are arranged at the through slots, and the through slots and the stator iron core are buckled into a whole by using the limiting supporting bosses. According to the inner stator, the coiling difficulty is reduced, the diameter of the motor stator is changed by controlling the degree of shrinking and combining degrees of the stator iron core under a condition that the motor stator iron core stamping piece mold is not changed, and only the size of the brocket is changed, thereby being adapted to stators with different diameters and greatly reducing the production cost of a motor.

Description

technical field [0001] The invention relates to an inner stator of an electric motor, in particular to an inner stator of an electric motor with adjustable outer diameter capable of realizing mechanized winding and a manufacturing method thereof. Background technique [0002] Most of the iron cores of traditional internal stator motors are made of integral circular punching materials stacked and riveted. The stator core and stator manufactured by this manufacturing process have the following problems: [0003] 1. The utilization rate of circular iron core punching material is low, generally not more than 30%. [0004] 2. If figure 1 , figure 2 As shown, the notch a1 of the stator core has a large opening, but the slot fullness rate is low. Probe-type winding machine is used for production. Since the winding probe needs to leave a space for itself to pass through when it moves in slot a, the slot full rate cannot be made too high, and because the space for the winding pro...
