Problems solved by technology

[0002] At present, most of the winding methods on the stator of the motor start from the upper end of the winding slot teeth, that is, after the winding of a winding slot teeth is completed, the wires will be connected obliquely upward from the bottom to the upper end of the adjacent winding slot teeth. Continue to arrange the wires at the bottom. This winding method cannot be neatly routed on the stator, and it will occupy more slots, making the slot full rate lower and affecting the use efficiency of the motor; and this oblique upward connection method Due to the longer distance, the resistance is higher and the energy consumption is larger during operation. At the same time, the copper wire required for this winding method is longer and the production cost is higher; therefore, it is necessary to improve it.

Embodiment 1

[0024] Embodiment 1: A composite winding process for motor stator openings, the process steps are as follows:

[0025] a. Fabrication of the stator core: the silicon steel sheets are laminated to form a stator core. The type of the stator core can be an outer stator core or an inner stator core; the stator core is evenly distributed and vertical after forming Upright winding groove teeth.

[0026] b. Opening the notch: punch the outer end of the winding slot teeth on the stator iron core through the punching equipment to form a certain depth of notch, the depth of the notch is less than 1 / 2 the spacing between adjacent winding slots , So as to avoid collisions during compounding; at the same time, a compound groove is opened on the outer end surface of the winding groove tooth, the compound groove can make the notch bend on both sides during compounding, making compounding more convenient. There are arc-shaped protrusions in the notches, and the arc-shaped protrusions can form arc...

Embodiment 2

[0038] Embodiment 2: The process of embodiment 2 is roughly the same as that of embodiment 1, and the difference is that: there are intermediate windings on the first phase winding, the second phase winding and the third phase winding, and the winding method of the intermediate winding It is: the copper wire connected from the head end of the winding starts to be wound from the upper end of the winding slot tooth, and then starts to wind the adjacent winding slot tooth from the direction perpendicular to the vertical line in the slot after the wiring is completed; After winding, it is directly connected to the end of the winding. The number of intermediate windings can be selected according to different motor rules and specifications, and will not be repeated here.

Abstract

The invention discloses a motor stator opening composite winding process. The process comprises the following steps of a, manufacturing a stator core; b, arranging a notch; c, carrying out first phasewinding; d, carrying out second phase winding; e, carrying out third phase winding; f, forming a composite notch; and g, carrying out winding wiring. The process has advantages that work efficiency and energy consumption of a motor can be increased and reduced because of a high slot fullness rate; and production cost can be effectively saved.

Description

Technical field [0001] The invention belongs to the technical field of motor stator winding, and in particular relates to a composite winding process for motor stator openings. Background technique [0002] At present, most of the winding methods on the motor stator start from the upper end of the winding slot, that is, after the winding of a winding slot is completed, it will be connected diagonally upwards from its bottom to the upper end of the adjacent winding slot. The part continues to wire, this winding method cannot be neatly routed on the stator, it will occupy more slots, making the slot full rate lower, affecting the efficiency of the motor; and this oblique upward connection method Due to the longer distance, the higher the resistance and the higher energy consumption during operation. At the same time, the copper wire required by this winding method is longer and the production cost is higher; therefore, it is necessary to improve. Summary of the invention [0003] T...
