The advantages are: the rotor punching is improved by using a simple structure, and the internal air flow circulates from the guide holes through the rotation of the rotor core to dissipate heat, thereby improving the heat dissipation effect, reducing the temperature rise of the motor, improving the motor performance, and increasing the service life of the motor.

[0003] In the prior art including the above patents, the rotor core weight reduction holes are mainly used to dissipate heat for the rotor body, which is not convenient for heat dissipation protection of the winding. Utility Model Content

[0004] The purpose of the present invention is to provide a rotor core with a self-heating structure to solve the problem of insufficient heat dissipation efficiency mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a rotor core with a self-heating structure, comprising a mounting tube, a ventilation groove is opened inside the mounting tube, and a through-tube hole is opened between the ventilation grooves through the mounting tube, a base is slidably arranged in the middle of the outer surface of the mounting tube, a winding plate 1 and a winding plate 2 are fixedly arranged on the upper end of the base, and a circular groove is opened in the middle of the base.

[0006] Furthermore, the mounting tube is composed of a circular tube and two mounting plates, and the circular tube and the mounting plates are used to install the winding assembly and connect with the external rotating shaft. The ventilation slots are opened on the circular tube, and there are eleven of them in total.

[0007] Furthermore, pipe-through holes are opened on the mounting plate, and the number of the pipe-through holes is consistent with the number of the ventilation slots. The pipe-through holes are composed of a circular hole and a rectangular placement slot, and the placement slot is used to clamp the two ends of the copper guide bar.

[0008] Furthermore, the base is set to an irregular arc shape, and a winding plate 1 is fixedly set on the left side of the upper end of the base, and a winding plate 2 is fixedly set on the right side of the upper end of the base, and the winding plate 1 and the winding plate 2 are adjacent to each other in a group.

[0009] Furthermore, the number of the bases corresponds to the number of the ventilation slots and the pipe holes, which is also eleven, and the bases are all located between the ventilation slots.

[0010] Furthermore, the size of the circular groove is consistent with that of the pipe-through hole, but the direction is opposite. The rectangular groove of the pipe-through hole faces the center of the circle. Bolts are fixed at both ends of the mounting tube, and there are two groups of bolts, each with six bolts.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the rotor core with a self-heating structure is reasonable and has the following advantages:

[0012] (1) During the operation of the rotor, external air can enter its interior, thereby achieving cooling of the winding and rotor. In addition, with the design of the through-holes, circular grooves and copper bars, the stability of the rotor during operation is significantly improved. Moreover, under the synergistic effect of the winding, the offset of the base will be reduced accordingly. In this way, while enhancing the cooling effect, the strength of the rotor is also effectively guaranteed;

[0013] (2) The base, winding plate 1 and winding plate 2 are specially designed so that they can be closely arranged with each other during the stamping operation. In this way, more workpieces can be processed at one time within the same area. At the same time, this design can also reduce the loss of scrap, thereby effectively reducing the waste of raw materials while improving the stamping efficiency. In addition, because a rotor is composed of multiple winding components, a single winding component can be formed with only one stamping. This advantage helps to improve the yield rate in the production process. In the event of defective products or damage to finished products, only the corresponding number of components need to be replaced, which can further reduce production losses and bring higher economic benefits and quality assurance to the production process.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 , a technical solution provided by the utility model:

[0021] In this embodiment, a rotor core with a self-heating structure includes a mounting tube 1 with ventilation slots 2 defined within the mounting tube 1. A through-hole 3 is defined between the ventilation slots 2 and extends through the mounting tube 1. A base 5 is slidably mounted in the middle of the outer surface of the mounting tube 1. Winding plates 1 6 and 7 are fixedly mounted on the upper ends of the base 5. A circular groove 8 is defined in the middle of the base 5.

[0022] In this embodiment, the mounting tube 1 consists of a circular tube and two mounting plates. The circular tube and the mounting plates are used to install the winding assembly and connect with the external rotating shaft. The ventilation slots 2 are opened on the circular tube, and there are eleven of them in total.

[0023] In this embodiment, the pipe-through holes 3 are opened on the mounting plate, and the number of the pipe-through holes 3 is consistent with the number of the ventilation slots 2. The pipe-through holes 3 are composed of a circular hole and a rectangular placement slot, and the placement slot is used to clamp the two ends of the copper guide bar.

[0024] In this embodiment, the base 5 is set to an irregular arc shape, a winding plate 6 is fixedly set on the left side of the upper end of the base 5, and a winding plate 2 7 is fixedly set on the right side of the upper end of the base 5, and the winding plates 1 6 and 2 7 are adjacent to each other in a group.

[0025] In this embodiment, the number of the bases 5 corresponds to the number of the ventilation slots 2 and the pipe holes 3 , which is also eleven. The bases 5 are all located between the ventilation slots 2 .

[0026] In this embodiment, the size of the circular groove 8 is consistent with that of the pipe hole 3, but the direction is opposite. The rectangular groove of the pipe hole 3 faces the center of the circle. Bolts 4 are fixed at both ends of the mounting tube 1, and there are two groups of bolts 4, each with six.

[0027] Working principle: When the rotor rotates, the surrounding air can be sucked in under the guidance of the winding plate 6. The external air will pass through the middle of the winding plate and be discharged to the middle through the ventilation slot 2. At this time, the winding and the entire device can be cooled at the same time. At the same time, the air will also cool the copper bars through the circular slot 8. Using two cooling methods to cool the device can increase the cooling efficiency.

[0028] During installation, first install a row of bases 5 in the installation tube 1 and align them, then pass the copper conductor bars through the tube holes 3 and the circular grooves 8 to fix the bases 5, and finally wind the windings on the winding board. At this time, the bases 5 can be firmly fixed under the action of the windings and the copper conductor bars.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
