The main function of the rotating rotor core is to conduct the magnetic field and constitute one of the magnetic circuits of the motor or generator. Through the magnetic conductivity of the core, the magnetic field can be conducted inside the core, thereby forming a small closed magnetic circuit, providing the necessary magnetic field support for the normal operation of the motor or generator. The rotating rotor core has excellent magnetic conductivity and permeability, which can reduce magnetic resistance, magnetic loss and hysteresis, improve the magnetic circuit efficiency of the motor or generator, and reduce the energy consumption and loss of the electromagnetic system. By fixing and guiding the magnetic lines of force, the rotating rotor core can also reduce the leakage of the magnetic field, make the magnetic field more concentrated and stable, and improve the working efficiency and performance of the motor or generator. The rotating rotor core can also support the winding coil to ensure the structural stability and accurate position of the coil, which is conducive to the installation and fixation of the winding coil and ensure the normal operation of the motor or generator.

The rotor core of the utility model can ensure the concentricity of the rotating shaft and the shaft hole, avoid scratches on the shaft during rotation, improve the bearing capacity of the rotor core, keep the motor running smoothly, and reduce noise at the same time. After rust prevention treatment, it is not easy to rust and has a long service life.

[0004] Although the rotor core in the above application can ensure the concentricity of the rotating shaft and the shaft hole, avoid scratches on the rotating shaft during rotation, improve the load-bearing capacity of the rotor core, keep the motor running smoothly, and reduce noise, and is rust-proof treated, not easy to rust, and has a long service life, corresponding teeth are arranged around the rotor core for fixing the copper wire. The structure of the existing rotor core laminations and the chip design are not reasonable. The coil is wound on the laminated core and the rotor is obtained through multiple processes. During operation, the coil is easy to fall off and become loose, and the falling of the coil affects the working efficiency of the motor. Utility Model Content

[0015] 1. In the utility model, the protrusion is pulled when the wire is released, and a telescopic spring is fixed to the bottom of the protrusion. The protrusion is pulled under the drive of the telescopic spring. The placement space of the winding is increased by pulling the protrusion, and the protrusion rebounds under the action of the telescopic spring after the winding is completed, so that the coil is fixed.

[0022] The following will be combined with the drawings of the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: a rotating rotor core, including a rotor core body 1, a connecting rod 6 is fixedly connected to the outer wall of the rotor core body 1, a protrusion 2 is fixedly connected to the top of the connecting rod 6, a telescopic spring 8 is fixedly connected to the bottom of the protrusion 2, one end of the telescopic spring 8 is fixedly connected to the outer wall of the rotor core body 1, and wedges 7 are fixedly connected to both sides of the protrusion 2.

[0024] Specifically, the wedge block 7 is fixed by the protrusion 2, and there is a spacing between two adjacent wedge blocks 7. The space formed by the two adjacent wedge blocks 7 and the outer wall of the rotor core body 1 is a wire release groove. When winding, the coil is put in from the spacing between the two wedge blocks 7. One end of the telescopic spring 8 is fixedly connected to the bottom of the protrusion 2, and the other end of the telescopic spring 8 is fixedly connected to the outer wall of the rotor core body 1. The telescopic spring 8 runs through the middle of the connecting rod 6. When releasing the wire, the protrusion 2 is pulled to increase the placement space for winding, and after the winding is completed, the protrusion 2 rebounds under the action of the telescopic spring 8 to fix the coil. The wedge block 7 can prevent the coil from loosening when the motor is working, so as to avoid affecting the normal operation of the motor.

[0025] Reference Figure 2 The wedge block 7 includes an inclined portion 701 and a rounded corner portion 702, wherein the inclined portion 701 is a straight inclined surface, and the rounded corner portion 702 is an arc surface.

[0026] Specifically, the coil contacts the inclined portion 701 when being placed, and the inclined portion 701 is a slope to facilitate the placement of the coil. When the coil is placed in the wire-releasing groove, it passes through the rounded corner portion 702, and the rounded corner portion 702 is an arc-shaped structure that can protect the wire harness so that it is not easily damaged when sliding in.

[0027] The inclined portion 701 is in an arc shape convex upward.

[0028] Specifically, the arc-shaped design of the inclined portion 701 enables the coil to be conveniently placed. The coil contacts the inclined portion 701 and then slides into the wire placing groove through the rounded corner portion 702 .

[0029] Reference Figure 1 An axial hole 3 is provided in the middle of the rotor core body 1, an oil storage ring 4 is provided on the periphery of the axial hole 3, an oil outlet hole 5 is provided on the side of the oil storage ring 4 close to the axial hole 3, and the inner periphery of the axial hole 3 matches the rotating shaft.

[0030] Specifically, lubricating oil is stored in the oil storage ring 4 , and the lubricating oil flows out from the oil outlet hole 5 when the shaft hole 3 and the rotating shaft cooperate to lubricate the rotating shaft and reduce the friction between the rotating shaft and the shaft hole 3 .

[0031] Reference Figure 1 , the protrusion 2 is an isosceles trapezoidal shape.

[0032] Specifically, the two sides of the protrusion 2 are conveniently fixedly connected to the side walls of the wedge block 7 .

[0033] The connecting rods 6 are evenly distributed along the outer wall of the rotor core body 1 .

[0034] Specifically, the uniform distribution of the connecting rods 6 realizes the uniform distribution of the protrusions 2, thereby facilitating the winding of the wire harness.

[0035] Working principle: The rotating rotor core is convenient for the installation and fixation of the winding coil. The protrusion 2 is an isosceles trapezoid shape. The uniform distribution of the protrusion 2 facilitates the fixation of the coil. The two sides of the protrusion 2 are fixedly connected with wedge blocks 7. The space formed by the two adjacent wedge blocks 7 and the outer wall of the rotor core body 1 is a wire-releasing groove. When performing the winding operation, the coil is wound from the wire-releasing groove formed between the two adjacent wedge blocks 7. The wedge block 7 is divided into an inclined portion 701 and a rounded portion 702. When the coil is placed, the wire harness contacts the rounded portion 702. The arc-shaped design of the rounded portion 702 can effectively avoid damage to the coil during winding. The inclined portion 701 is a straight inclined surface to facilitate the coil to slide into the wire-releasing groove. The inclined portion 701 is an upwardly protruding arc shape, which can also facilitate the coil to slide into the wire-releasing groove. After the coil is placed in, the wedge block 7 can prevent the coil from falling off during operation. One end of the telescopic spring 8 is fixedly connected to the bottom of the protrusion 2, and the other end of the telescopic spring 8 is fixedly connected to the outer wall of the rotor core body 1. The telescopic spring 8 runs through the middle of the connecting rod 6. During winding, the protrusion 2 can be pulled outward under the action of the telescopic spring 8. After the winding is completed, the telescopic spring 8 pulls the protrusion 2 to fix the coil in the wire-releasing groove under the action of its own elastic force. Lubricating oil is stored in the oil storage ring 4. When the shaft hole 3 and the rotating shaft work together, the lubricating oil flows out from the oil outlet hole 5, which plays a role in lubricating the rotating shaft and reducing the friction between the rotating shaft and the shaft hole 3.
