Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a stator and rotor lamination for an electric motor. Background Technology

[0002] The main function of a motor is to convert electrical energy into mechanical energy, generating driving torque to serve as a power source for various devices and machines. In a motor, stator laminations and rotor laminations are two indispensable core components. Stator laminations are the stationary parts of the motor, while rotor laminations are the rotating parts.

[0003] Current stator and rotor laminations cannot provide a stable rotating magnetic field, which can easily cause jamming, affecting the overall structural integrity. Furthermore, the large electromagnetic forces can cause structural damage due to mutual interference.

[0004] Therefore, a new type of stator and rotor lamination for electric motors is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a stator and rotor lamination for an electric motor, in order to solve the problems mentioned in the background art, such as the inability to provide a stable rotating magnetic field, the tendency to jam, the impact on the overall structural integrity, and the large electromagnetic forces that cause mutual interference and damage to the structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stator and rotor lamination for an electric motor, comprising a stator lamination and a rotor lamination, wherein the stator lamination is located at the front end of the rotor lamination, and a stable magnetic field assembly is provided inside the rotor lamination; The magnetic field assembly includes a magnetic isolation groove. Multiple sets of permanent magnet grooves are equally spaced inside the rotor lamination. Multiple sets of magnetic isolation grooves are provided and are located on both sides of the inner end of each set of permanent magnet grooves. Multiple sets of heat dissipation holes are equally spaced through the outer end of the rotor lamination. The heat dissipation holes correspond one-to-one with the magnetic isolation grooves. As a further technical solution of this utility model, a shaft hole is provided through the center of the rotor lamination, and the top end of the shaft hole protrudes outward.

[0007] As a further technical solution of this utility model, the inner end of the stator lamination is circularly hollowed out, and the inner wall of the stator lamination protrudes outward to form the stator winding part.

[0008] As a further technical solution of this utility model, the two sides of the inner end of the stator winding section are symmetrically recessed and provided with limiting grooves, and a stator winding groove is formed between the two sets of stator winding sections.

[0009] As a further technical solution of this utility model, the outer end of the stator lamination is provided with multiple sets of inner grooves at equal intervals, and the outer end of the stator lamination is provided with multiple sets of mounting holes at equal intervals.

[0010] As a further technical solution of this utility model, the inner groove is provided with positioning holes, and the mounting holes are arranged alternately with the inner groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the stator and rotor laminations used in this motor not only achieve the function of stabilizing the magnetic field and achieving the function of high rigidity, but also achieve the function of safety; By incorporating magnetic shielding slots, permanent magnet slots, and heat dissipation holes, the rotor laminations are connected to the motor shaft via shaft holes, supporting the rotation of the entire rotor laminations. Driven by electromagnetic force, the rotors rotate at high speed. The magnetic shielding slots and permanent magnet slots work together to quickly cut the magnetic lines of force of the stator magnetic field, thereby generating induced current or being subjected to electromagnetic torque, which in turn drives the motor shaft to rotate, converting electrical energy into mechanical energy and providing a uniform and stable rotating magnetic field. This effectively prevents electromagnetic force from damaging the overall structure and ensures long-term safe operation. The heat generated during the rotation of the rotor laminations is quickly dissipated to the outside through multiple sets of heat dissipation holes, preventing heat accumulation. By setting up a stator winding section, a stator winding groove, and a limiting groove, the enameled wire is conveniently wound and installed on the outside of the stator winding section through the limiting groove, which also serves to limit and fix it, effectively preventing the enameled wire from loosening or even falling off, strengthening the connection between the enameled wire and the stator laminations. At the same time, the stator winding groove provides a safe space for wire release, avoiding wear on the enameled wire and affecting its performance, thus greatly extending its service life. The stator laminations are equipped with an inner groove, positioning holes, and mounting holes. The positioning holes facilitate the installation and fixation of the stator laminations, improving the firmness between the stator laminations and the inner wall of the equipment, ensuring the stability of the stator laminations themselves, and keeping them in a fixed state for a long time. Multiple sets of mounting holes facilitate installation and fixation. Attached Figure Description

Multiple sets of mounting holes 12 facilitate installation and fixing.

[0018] Working Principle: In use, this invention connects the rotor lamination 3 to the motor shaft via the shaft hole 4, supporting the rotation of the entire rotor lamination 3.
