A rotor end plate of a permanent magnet motor with turbulence function

Abstract

This utility model discloses a permanent magnet motor rotor end plate with a turbulence-disrupting function, relating to the field of mechanical manufacturing technology. The utility model includes a motor shaft, with a first rotor end plate and a second rotor end plate respectively mounted on both sides of the motor shaft surface. Turbulence-disrupting plates are fixedly connected inside both the first and second rotor end plates. The first and second rotor end plates are fixed to the front and rear ends of the motor shaft, providing support and protection. Their surfaces are equipped with turbulence-disrupting plates, which effectively disturb the surrounding airflow during motor rotation. When the motor is running, the high-speed rotation of the rotor drives the turbulence-disrupting plates on the end plates to cut the airflow, thereby generating airflow vortices inside the motor. These airflow vortices diffuse outwards, promoting the circulation of air inside the motor, effectively carrying away the heat generated by the rotor and stator, helping the motor dissipate heat, and maintaining stable motor operation.

Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology, and in particular relates to a rotor end plate of a permanent magnet motor with a turbulence function. Background Technology

[0002] A permanent magnet motor is a type of motor that uses permanent magnet materials (such as neodymium iron boron and AlNiCo) to generate a magnetic field. Unlike traditional induction motors, permanent magnet motors do not rely on external current to generate a magnetic field. Instead, they utilize built-in permanent magnets to provide a stable magnetic field, thus simplifying motor design and reducing energy loss. The basic working principle of a permanent magnet motor is similar to other motors, generating motion through the interaction of current and magnetic field. Its stator (stationary part) is typically composed of windings, which form a rotating magnetic field when powered on. The rotor (rotating part) is composed of permanent magnets. The magnetic field on the rotor interacts with the magnetic field of the stator, generating torque and driving the rotor to rotate. Permanent magnet motors are widely used in industrial automation, home appliances, wind power generation, electric vehicles, drones, air conditioners, washing machines, and other fields.

[0003] Currently, permanent magnet motor rotors on the market lack airflow disturbance function, resulting in weak air circulation capacity inside the motor cavity. During operation, due to the limitation of rotor rotation and airflow, the cooling effect is poor, which may lead to motor overheating, thereby affecting the performance and service life of the motor. To address this issue, we provide a permanent magnet motor rotor end plate with disturbance function to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a permanent magnet motor rotor end plate with a turbulence function, which solves the problem that the permanent magnet motor rotor in the prior art generally lacks airflow turbulence function, resulting in weak air circulation capacity inside the motor cavity.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model is a permanent magnet motor rotor end plate with a turbulence function, including a motor shaft. A first rotor end plate and a second rotor end plate are respectively installed on both sides of the surface of the motor shaft. Turbulence plates are fixedly connected inside the first rotor end plate and the second rotor end plate. A rotor core is installed on the surface of the motor shaft.

[0007] The present invention is further configured such that a permanent magnet is installed on the surface of the rotor core, and a rotor steel sleeve is installed on the surface of the rotor core.

[0008] The present invention is further configured such that a rotor sleeve is installed on the surface of the motor shaft, and the rotor core is disposed between the first rotor end plate and the second rotor end plate.

[0009] The present invention is further configured such that a through-shaft hole is provided inside the first rotor end plate and the second rotor end plate, and a rotor weight reduction hole is provided inside the first rotor end plate and the second rotor end plate.

[0010] The present invention is further configured such that the rotor weight reduction holes are eight in number and are arranged circumferentially with the through-shaft hole as the axis.

[0011] The present invention is further configured such that there are eight baffles, the cross-section of the baffles is wedge-shaped, and the baffles have airflow disturbance function.

[0012] The present invention has the following beneficial effects: The first rotor end plate and the second rotor end plate are fixed at the front and rear ends of the motor shaft, playing a supporting and protective role. Their surfaces are equipped with baffles, which can effectively disturb the surrounding airflow during the motor rotation. When the motor is running, the high-speed rotation of the rotor drives the baffles on the end plates to cut the airflow, thereby generating airflow vortices inside the motor. These airflow vortices diffuse outward, promoting the circulation of air inside the motor, thereby effectively removing the heat generated by the rotor and stator, helping the motor to dissipate heat and maintain the stable operation of the motor.

[0020] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] Please see Figure 1-5 This utility model is a permanent magnet motor rotor end plate with turbulence function, including a motor shaft 1, a first rotor end plate 2 and a second rotor end plate 3 respectively installed on both sides of the surface of the motor shaft 1, turbulence plates 4 are fixedly connected inside the first rotor end plate 2 and the second rotor end plate 3, and a rotor core 5 is installed on the surface of the motor shaft 1.

[0023] Specifically, the cross-section of the spoiler 4 is designed in a wedge shape. This design allows the spoiler 4 to generate effective airflow disturbance when the motor rotates counterclockwise and clockwise. When the motor rotates, the air is compressed by the wedge-shaped cross-section, forcing the airflow to flow along the inclined surface of the spoiler 4. Due to the geometric characteristics of the wedge, the airflow is accelerated and diffused outward under the action of the inclined surface. This airflow not only enhances the circulation of air inside the motor and effectively removes heat, but also promotes the improvement of heat dissipation efficiency, ensuring that the motor can maintain a stable operating temperature under different loads and working conditions.

Their surfaces are equipped with baffles 4, which can effectively disturb the surrounding air flow during the motor rotation. When the motor is running, the high-speed rotation of the rotor drives the baffles 4 on the end plate to cut the airflow, thereby generating airflow vortices inside the motor. These airflow vortices diffuse outward, promoting the circulation of air inside the motor, thereby effectively removing the heat generated by the rotor and stator, helping the motor to dissipate heat, and maintaining the stable operation of the motor. It can be widely used in the motor manufacturing industry.
