Embodiment Construction

[0011] Such as Figure 1-2 As shown, the stator structure of the motor according to the embodiment of the present invention includes a stator housing 1, which is integrally formed, and a number of uniformly arranged stator slots 2 are arranged on the inner side of the stator housing 1. Beads 3 are respectively installed on the sides, so that the space for the stator slot 2 to accommodate the windings forms a "convex" shape. The stator slot 2 is arranged obliquely, that is, it is installed in a cable-stayed structure.

[0012] The stator housing 1 is circular.

[0013] The motor stator structure solves the problem of winding slippage, and can make the winding stability of the motor better.

Abstract

The invention discloses a motor stator structure. The motor stator structure comprises a stator shell, and is characterized in that the stator shell is integrally formed, a plurality of stator grooves arranged evenly are arranged on the inner side of the stator shell, two inner side edges of groove openings are respectively provided with a pressing bar, and therefore the space of the stator grooves used for containing a coil is shaped like a Chinese character 'tu'. Two ends of the pressing bar are fixed with the rotator shell through locating bars, and the locating bars are arranged in an inclined mode relative to the stator grooves, namely in a cable-stayed mode. The motor stator structure solves the problem of slipping of the coil and enables coil stability of a motor to be good.

Description

technical field [0001] The invention is a motor stator structure. Background technique [0002] The slot structure of the stator often adopts a square structure. Due to the poor stability of the square structure, the windings in the slot are easy to fall off, resulting in unstable operation of the motor. Contents of the invention [0003] The purpose of the present invention is to provide a motor stator structure to solve the problems of heat dissipation and isolated output of a three-phase asynchronous motor. [0004] The purpose of the present invention is specifically achieved through the following technical solutions: [0005] A motor stator structure, comprising a stator shell, characterized in that the stator shell is integrally formed, a number of evenly arranged stator slots are arranged on the inner side of the stator shell, and beading bars are respectively installed on the two inner sides of the slot, The space for the stator slot to accommodate the winding is...
