Description

Technical Field

[0001] The utility model relates to the technical field of stator and rotor cores, in particular to a high-efficiency and energy-saving motor stator and rotor core. Background Art

[0002] The motor stator and rotor cores are commonly used anti-interference components in electronic circuits. They have a good suppressing effect on high-frequency noise. The stator core has excellent magnetic conductivity and serves as a fixed coil support.

[0003] As an important equipment in modern industry, the performance of motors directly affects the operating efficiency and energy consumption of the entire system. The traditional motor stator and rotor core design often has problems such as large energy loss and poor heat dissipation, which not only increases the operating cost of the motor, but also limits the application of motors in the field of high efficiency and energy saving. In addition, when the stators are stacked and connected, the stator core is prone to position displacement during the stacking process, resulting in an unstable stator structure after stacking, which may affect the overall performance of the motor. In response to the above situation, we have launched high-efficiency and energy-saving motor stator and rotor cores. Utility Model Content

[0004] The utility model aims to provide a high-efficiency and energy-saving motor stator and rotor core to solve the problem of poor heat dissipation in the above-mentioned background technology.

[0005] The technical solution of the utility model is:

[0006] A first stator core, wherein a positioning groove is provided on a lower end surface of the first stator core, a second stator core is laminated on a lower surface of the first stator core, a protrusion is fixedly connected to an upper end surface of the second stator core, and the protrusion is engaged in the positioning groove;

[0007] Ventilation slots are evenly distributed on the outer walls of the first stator core and the second stator core, a rotor core is arranged inside the first stator core and the second stator core, and heat dissipation channels are evenly opened on the outer walls of the rotor core.

[0008] Furthermore, twelve groups of ventilation slots are provided along the outer wall of the first stator core, and the inner wall of each group of ventilation slots is fixedly connected with a first heat sink.

[0009] The ventilation slots and the first heat sink can effectively improve the heat dissipation performance of the stator core. By increasing the heat dissipation surface area and improving air circulation, heat can be transferred from the core surface to the surrounding air more quickly, thereby effectively reducing the stator temperature and improving the heat dissipation effect of the motor.

[0010] Furthermore, a second heat sink is fixedly connected to the inner wall of the heat dissipation channel.

[0011] The heat dissipation channel on the outer wall of the rotor core and the second heat sink effectively reduce the overall operating temperature of the motor, help slow down the aging of the internal components of the motor, and improve the stability and reliability of the motor. By reducing the rotor temperature, the performance of the motor can be improved, the magnetic permeability of the rotor can be increased, and the iron loss can be reduced, thereby improving the efficiency and output performance of the motor.

[0012] The utility model provides a high-efficiency and energy-saving motor stator and rotor core through improvement, which has the following improvements and advantages compared with the prior art:

[0013] First: In the utility model, the first stator core is overlapped with the second stator core by engaging the first stator core with the positioning groove and the protrusion, so as to ensure the stable position during assembly and operation, avoid displacement or looseness, ensure the quality of the equipment, increase the stability and rigidity of the whole structure, reduce the possibility of vibration or deformation during operation, and help to improve the operation stability and reliability of the motor. The superposition of the second stator core can optimize the magnetic circuit, reduce the magnetic resistance, and improve the magnetic field conduction efficiency, thereby improving the efficiency and performance of the motor.

[0014] Second: The utility model can effectively improve the heat dissipation performance of the stator core through the ventilation grooves and the first heat sink. By increasing the heat dissipation surface area and improving air circulation, the heat can be transferred from the core surface to the surrounding air more quickly, thereby effectively reducing the stator temperature and improving the heat dissipation effect of the motor. The outer wall heat dissipation channel and the second heat sink of the rotor core can effectively reduce the overall operating temperature of the motor, help slow down the aging rate of the internal components of the motor, and improve the stability and reliability of the motor. By reducing the rotor temperature, the performance of the motor can be improved, the magnetic permeability of the rotor can be increased, and the iron loss can be reduced, thereby improving the efficiency and output performance of the motor.

[0023] In this embodiment: the first stator core 1 is arranged to be engaged with the second stator core 2 by the positioning groove 101 and the protrusion 201 to ensure its stable position during assembly and operation, avoid displacement or looseness, ensure the quality of the equipment, increase the stability and rigidity of the entire structure, reduce the possibility of vibration or deformation during operation, and help improve the operation stability and reliability of the motor. The superposition of the second stator core 2 can optimize the magnetic circuit, reduce magnetic resistance, and improve the magnetic field conduction efficiency, thereby improving the efficiency and performance of the motor. Then, the stator core is formed by stacking silicon steel sheets with a thickness of 0.35 mm. The surface of the silicon steel sheets is coated with an insulating layer 3 to reduce eddy current losses, and in the first The outer walls of the stator core 1 and the second stator core 2 are evenly distributed with ventilation grooves 4 and the first heat sink 401, which can effectively improve the heat dissipation performance of the stator core. By increasing the heat dissipation surface area and improving air circulation, heat can be transferred from the core surface to the surrounding air more quickly, thereby effectively reducing the stator temperature and improving the heat dissipation effect of the motor. The outer wall heat dissipation channel 6 and the second heat sink 601 of the rotor core 5 effectively reduce the overall operating temperature of the motor, help slow down the aging rate of the internal components of the motor, and improve the stability and reliability of the motor. By reducing the rotor temperature, the performance of the motor can be improved, the magnetic permeability of the rotor can be increased, and the iron loss can be reduced, thereby improving the efficiency and output performance of the motor.

[0024] In a preferred embodiment, the first stator core 1 is made of stacked silicon steel sheets with a thickness of 0.35 mm, and the surface of the silicon steel sheets is coated with an insulating layer 3 to reduce eddy current losses. The rotor core 5 is made of iron nitride material. The hysteresis loss and eddy current loss of the iron nitride material are relatively low, especially at high frequencies, ensuring that the motor generates less heat during operation and can be more effectively converted into mechanical energy, thereby improving the energy utilization of the motor and reducing energy consumption.

[0025] In a preferred embodiment, a motor shaft 7 is connected to the center of the rotor core 5, and a heat dissipation fan blade 8 is fixedly connected to the outer surface of the motor shaft 7.

By providing a U-shaped slot on the inner wall of the stator core, the magnetic field distribution can be optimized, the magnetic resistance can be reduced, and the magnetic flux can pass more smoothly, thereby improving the efficiency of the motor. When a coil is wound in the stator core and current is passed through, the current will generate a magnetic field in the core, and the presence of the U-shaped slot allows the magnetic field to diffuse more freely, reducing the magnetic resistance, so that the magnetic field can act more effectively on the rotor, thereby driving the motor to operate.
