Description

Technical Field

[0001] This utility model relates to the field of stator and rotor core technology, specifically a high-efficiency and energy-saving stator and rotor core structure. Background Technology

[0002] Electric motors are widely used in modern industry and daily life, covering many fields such as power, transportation, and home appliances. However, traditional stator and rotor core structures suffer from significant energy losses during motor operation, which not only increases energy consumption but also raises operating costs. Furthermore, the winding slot design of some traditional stator and rotor cores is not optimal, leading to unstable torque output and low efficiency. In addition, some traditional stator and rotor cores have poor structural stability, making them prone to lamination displacement during long-term operation, affecting normal motor operation and even shortening the motor's lifespan. Therefore, those skilled in the art have developed a highly efficient and energy-saving stator and rotor core structure to address the problems mentioned in the background. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A high-efficiency and energy-saving stator and rotor core structure includes a stator core and a rotor core. The stator core is composed of multiple sets of stator laminations, and the rotor core is composed of multiple sets of rotor laminations. The surface of the stator laminations is provided with uniformly arranged stator winding slots, and the surface of the stator laminations is also provided with opposing riveting slots.

[0006] Furthermore, the rotor laminations have first rotor winding slots and second rotor winding slots at different distances from the center, and the first rotor winding slots and second rotor winding slots are arranged in a ring on the rotor laminations.

[0007] Furthermore, the rotor laminations are provided with uniformly arranged bar slots, which are used to insert magnetic conductors.

[0008] Furthermore, the rotor laminations are provided with uniformly arranged pin grooves on their surface, which are used to insert key pins.

[0009] Furthermore, both the stator laminations and the rotor laminations are made of cold-rolled non-oriented silicon steel sheets.

[0010] By adopting the above technical solution

[0011] Compared with the prior art, the beneficial effects of this utility model are:

The stator winding slots evenly arranged on the stator laminations and the first and second rotor winding slots arranged in a ring at different distances from the center on the rotor laminations optimize the winding distribution, making the magnetic field distribution inside the motor more uniform, improving the motor's operating efficiency and performance stability. At the same time, the rotor laminations are hollowed out to reduce the weight of the rotor core, achieving a lightweight design, reducing the rotor's moment of inertia, enabling the motor to respond to control signals more quickly, and improving the motor's dynamic performance and energy efficiency. The stator and rotor laminations are made of cold-rolled non-oriented silicon steel sheets, whose high magnetic permeability significantly improves the magnetic field conduction efficiency, reducing energy loss during magnetic field conduction, thereby achieving high efficiency and energy saving.

[0017] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0018] Please see Figures 1-3This utility model provides an embodiment of a high-efficiency and energy-saving stator and rotor core 2 structure, including a stator core 1 and a rotor core 2. The stator core 1 is composed of multiple sets of stator laminations 101 stacked together, and the rotor core 2 is composed of multiple sets of rotor laminations 201 stacked together. The surface of the stator laminations 101 is provided with uniformly arranged stator winding slots 102, and the surface of the stator laminations 101 is also provided with opposing riveting slots 103. The stator core 1 is composed of multiple sets of stator laminations 101 stacked together. The uniformly arranged stator winding slots 102 on the surface of the stator laminations 101 are used to place the stator windings. When alternating current is applied to the stator windings, an alternating magnetic field is generated. Since the stator laminations 101 are made of cold-rolled non-oriented silicon steel sheet material, this material has high magnetic permeability and can efficiently conduct magnetic fields, making the magnetic field generated by the stator more stable and stronger. The riveting slots 103 are used to rivet the stator laminations 101 during stacking to ensure the stability of the stator core 1 structure.

[0019] In this embodiment, the rotor lamination 201 has a first rotor winding slot 202 and a second rotor winding slot 203 at different distances from the center. The first rotor winding slot 202 and the second rotor winding slot 203 are arranged in a ring on the rotor lamination 201. The rotor lamination 201 also has uniformly arranged bar slots 204 for inserting magnetic conductors. The rotor lamination 201 also has uniformly arranged pin slots 205 for inserting pins. Both the stator lamination 101 and the rotor lamination 201 are made of cold-rolled non-oriented silicon steel sheets. The rotor core 2 is composed of multiple sets of rotor laminations 201 stacked together. The first rotor winding slot 202 and the second rotor winding slot 203, which are located at different distances from the center of the circle, are arranged in a ring to house the rotor windings. Under the action of the alternating magnetic field generated by the stator, an induced current is generated in the rotor windings, which in turn generates an electromagnetic force to drive the rotor to rotate. The uniformly arranged bar slots 204 are inserted with magnetic conductors to further enhance the magnetic permeability of the rotor and improve the electromagnetic induction efficiency. The pin slots 205 are inserted with pins to enhance the connection strength between the rotor laminations 201 and ensure the structural stability of the rotor when rotating at high speed. At the same time, the rotor laminations 201 are also made of cold-rolled non-oriented silicon steel sheets, ensuring good magnetic permeability.

[0020] The stator winding slots 102 evenly arranged on the stator laminations 101 and the first rotor winding slots 202 and the second rotor winding slots 203 arranged in a ring at different distances from the center on the rotor laminations 201 optimize the winding distribution, making the magnetic field distribution inside the motor more uniform, improving the motor's operating efficiency and performance stability. At the same time, the rotor laminations 201 are hollowed out to reduce the weight of the rotor core 2, achieving a lightweight design, reducing the rotor's moment of inertia, enabling the motor to respond to control signals more quickly, and improving the motor's dynamic performance and energy efficiency. The stator laminations 101 and the rotor laminations 201 are made of cold-rolled non-oriented silicon steel sheets, whose high magnetic permeability significantly improves the magnetic field conduction efficiency and reduces energy loss during magnetic field conduction, thereby achieving high efficiency and energy saving.

[0021] This specification describes embodiments, but not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
