Description

Technical Field

[0001] The utility model belongs to the technical field of washing machines, and in particular relates to a stator core structure of a washing machine air dryer motor with high material utilization. Background Art

[0002] The stator core of the washing machine dryer motor is an important part of the motor magnetic circuit. It is composed of multiple laminations stacked together. A circular hole for inserting the rotor is opened in the center, and multiple coil slots interconnected with the circular hole are evenly formed along the circumference of the circular hole. The lamination has four sides with a zigzag structure, and the middle part of each side is protruding outward.

[0003] The outer peripheral edge of the stator core is changed from a straight line to a zigzag line, and the opening width of the coil slot is reduced. This not only increases the size of the yoke but also reduces the magnetic flux density and the loss of the stator core, thereby improving the efficiency of the motor.

[0004] At present, most stator cores use one-piece structure iron core sheets. This type of one-piece structure iron core sheet will generate a large amount of waste during the manufacturing process. In addition, the manufacturing of each iron core sheet requires a complete and sufficient size of material. Therefore, the overall material consumption rate is high when manufacturing the iron core sheets. Therefore, it is necessary to improve according to the defects in the manufacturing of the existing stator core. Utility Model Content

[0005] The purpose of the utility model is to provide a stator core structure of a washing machine and dryer motor with high material utilization. At present, most stator cores adopt an integrated structure iron core sheet. Such integrated structure iron core sheets will generate a large amount of waste during the manufacturing process, and each iron core sheet requires a complete and sufficient size of material to be manufactured. Therefore, the overall material consumption rate is high when manufacturing the iron core sheets. Therefore, it is necessary to improve the problems according to the defects in the existing stator core manufacturing.

[0006] To achieve the above object, the utility model provides the following technical solutions: a stator core structure of a washing machine and air dryer motor with high material utilization, comprising a motor rotor, wherein the motor rotor is installed in a reserved through hole of a main stator sheet;

[0007] A first pair of interfaces is provided on one side of the main stator sheet, one side of the first pair of interfaces is riveted to a second pair of interfaces, the second pair of interfaces is opened at one end of the auxiliary stator sheet, an end angle is provided at the other end of the main stator sheet, and a notch is provided at the end of the end angle away from the end angle.

[0008] In order to achieve docking of the main stator sheet and the auxiliary stator sheet, as a preferred structure of the stator core of a washing machine and dryer motor with high material utilization rate in the utility model, the first pair of interfaces and the second pair of interfaces are both irregular inverted "Z" shaped structures, and the first pair of interfaces and the second pair of interfaces are interference connection structures.

[0009] In order to allow the next main stator sheet stamping material to punch out another complete main stator sheet when used, as a preferred structure of the stator core of a washing machine and dryer motor with high material utilization of the utility model, the size and shape of the end angle are the same as the size and shape of the first pair of interfaces, and the minimum lateral dimension between the two end angles is the same as the maximum lateral dimension of the notch.

[0010] The auxiliary stator sheets are butt-jointed with each other through the notch between the second pair of interfaces and the first pair of interfaces. As a preferred stator core structure of a washing machine and air dryer motor with high material utilization of the utility model, two second pair of interfaces are provided, and the two second pair of interfaces are symmetrical with respect to the longitudinal center line of the auxiliary stator sheets.

[0011] In order to make the sizes of the main stator sheet and the auxiliary stator sheet match each other, the maximum transverse vertical length of the main stator sheet is the same as the maximum transverse vertical length of the auxiliary stator sheet.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When in use, the main stator sheet and the auxiliary stator sheet are placed on the riveting ends of the corresponding riveting equipment, the two first mating interfaces and the two second mating interfaces are aligned, and then the main stator sheet and the auxiliary stator sheet are pressed together by the riveting machine, so that the two first mating interfaces and the two second mating interfaces are butted together through the interference structure. At the same time, the size between the two end angles of the main stator sheet is the same as the size of the notch, so that the manufacturing material of the main stator sheet can be used to punch a new notch portion along the material of the end angle portion during the next stamping. Therefore, when in use, the material utilization rate during the manufacturing of the entire stator can be greatly reduced through the above-mentioned structure of the main stator sheet and the auxiliary stator sheet.
