From a professional perspective, electric motors primarily operate based on the principle of electromagnetic induction, and their core components typically include a stator, rotor, and electromagnetic windings. In an electric motor, the stator, as the stationary part, is usually equipped with electromagnetic windings to generate a rotating magnetic field. The rotor, as the rotating part, rotates due to the force exerted by the rotating magnetic field through electromagnetic induction, thereby converting electrical energy into mechanical energy. Furthermore, electric motors come in various types to adapt to different application scenarios.

One end of the base is provided with a mounting seat, the mounting seat is provided with a mounting platform, the mounting platform is provided with a positioning element and a fixing element, the encoder module includes a circuit board and an encoder element, the encoder element is disposed on the circuit board, the positioning element is used to position the circuit board on the mounting platform, and the fixing element is used to fix the circuit board on the mounting platform.

[0007] A further improvement to the above solution is that the wiring trough includes a wiring section, a lead section, and an outlet section. The wiring section is located below the mounting platform, the lead section is disposed on the side of the base and is connected to the wiring section and the outlet section respectively, and the outlet section extends through the end of the base opposite to the mounting platform.

[0008] A further improvement to the above solution is that a fixed connection groove is provided at one end of the base, and a connection port is provided on the mounting base.

[0009] A further improvement to the above solution is that the positioning element is a positioning pin, and the circuit board is provided with a positioning groove, which is used to cooperate with the positioning pin to position the circuit board on the mounting table.

[0015] The beneficial effects of this utility model are:

[0016] Compared to existing motor encoder mounting structures, the positioning element of this invention ensures that the encoder module's circuit board is precisely positioned on the mounting platform. During motor operation, the encoder's mounting position is crucial for accurate signal acquisition and transmission. Precise positioning allows the encoder element to stably and accurately sense the motor's operating parameters, such as speed and angle, thus providing reliable data support for the motor control system and facilitating precise motor operation control. The fixing element firmly secures the circuit board to the mounting platform. Motor operation generates vibrations; if the encoder module is not securely fixed, connections may loosen or the position may shift, affecting the stability and accuracy of signal transmission. The fixing element effectively resists the vibrations and impacts generated by motor operation, ensuring the encoder module remains firmly mounted on the mounting platform, maintaining a stable connection between the encoder module and the motor, greatly enhancing the encoder's operational stability, and thus ensuring the motor's operational stability. This invention improves the overall performance of the motor, reduces malfunctions caused by encoder installation problems, extends motor lifespan, and meets the needs of various application scenarios with high requirements for motor operational stability.

[0017] The encoder mounting mechanism of the motor accurately acquires the position and speed information of the motor rotor assembly. Since the rotor assembly and stator assembly are positioned opposite each other, they work together to achieve energy conversion and power output. The encoder mounting mechanism can monitor the status parameters of the rotor assembly in real time. This allows the motor control system to dynamically adjust the current and magnetic field of the stator assembly based on this precise data, ensuring efficient and stable operation of the motor under various working conditions. This contributes to improving the reliability of motor operation. By accurately feeding back the motor's operating status, potential anomalies, such as rotor speed fluctuations and position deviations, can be detected promptly and fed back to the control system. The control system then takes corresponding measures to adjust and correct these issues, preventing motor failures due to abnormal operation and significantly extending the motor's service life.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-6As shown, in one embodiment of this utility model, an encoder mounting mechanism is provided, including a base 1 and an encoder module 2. One end of the base 1 is provided with a mounting seat 11, and the mounting seat 11 is provided with a mounting platform 12. The mounting platform 12 is provided with a positioning element 13 and a fixing element 14. The encoder module 2 includes a circuit board 21 and an encoder element 22. The encoder element 22 is mounted on the circuit board 21. The positioning element 13 is used to position the circuit board 21 on the mounting platform 12, and the fixing element 14 is used to fix the circuit board 21 on the mounting platform 12. In this embodiment, the positioning element 13 ensures that the circuit board 21 of the encoder module 2 can be accurately positioned on the mounting platform 12. During motor operation, the encoder mounting position is crucial for accurate signal acquisition and transmission. Precise positioning enables the encoder element 22 to stably and accurately sense the motor's operating status parameters, such as speed and angle, thereby providing reliable data support for the motor control system and facilitating precise control of motor operation. The fixing element 14 firmly fixes the circuit board 21 to the mounting platform 12. Motor operation generates vibrations. If the encoder module 2 is not securely fixed, it may lead to loose connections and positional misalignment, thus affecting the stability and accuracy of signal transmission. The fixing element 14 effectively resists the vibrations and impacts generated by the motor, ensuring that the encoder module 2 is always firmly mounted on the mounting platform 12 of the base 1. This maintains a stable connection between the encoder module 2 and the motor, greatly enhancing the stability of the encoder's operation and thus ensuring the stability of the motor's operation. This embodiment improves the overall performance of the motor, reduces malfunctions caused by encoder installation problems, extends the motor's service life, and meets the needs of various application scenarios with high requirements for motor operational stability.

[0028] A wiring groove 15 is provided at the center of the base 1, with one end of the wiring groove 15 connected to the mounting platform 12. A connector 211 is provided on the circuit board 21, with the terminal of the connector 211 facing the wiring groove 15. Specifically, the wiring groove 15 includes a wiring portion 151, a lead portion 152, and a lead-out portion 153. The wiring portion 151 is located below the mounting platform 12, and the lead portion 152 is located on the side of the base 1 and is connected to both the wiring portion 151 and the lead-out portion 153. The lead-out portion 153 extends through the end of the base 1 opposite to the mounting platform 12. In this embodiment, the wiring groove 15 provides a reliable guarantee for motor operation. The wiring portion 151 is located below the mounting platform 12, facilitating precise connection of the terminal of the connector 211 on the circuit board 21, ensuring a stable connection of the signal transmission line. The lead portion 152 is cleverly located on the side of the base 1, effectively guiding the line direction, avoiding messy and crossed lines, reducing signal interference, and improving the accuracy of signal transmission. The outgoing cable 153 extends through the other end of the base 1, allowing the cable to be smoothly led out and connected to other control components of the motor, ensuring the integrity of the entire electrical system. This not only makes the internal wiring of the motor more organized and orderly, but also greatly improves the stability of motor operation and reduces the probability of failures caused by wiring problems.

[0029] One end of the base 1 is provided with a fixed connection groove 16, and the mounting base 11 is provided with a connection port 111, which is located on the fixed connection groove 16. In this embodiment, precise positioning and stable connection between the encoder mounting base 11 and the base 1 are achieved. During motor operation, the stable connection structure effectively reduces encoder displacement or loosening caused by factors such as vibration and impact, ensuring accurate measurement and feedback of motor operating parameters by the encoder. It avoids measurement errors caused by installation deviations, thereby providing accurate data support for motor control. The stable connection method helps improve the stability and reliability of the motor control system, enabling the motor to maintain stable operation under various working conditions.

[0030] Positioning element 13 is a positioning pin, and the circuit board 21 is provided with a positioning groove 212. The positioning groove 212 is used to cooperate with the positioning pin to position the circuit board 21 on the mounting platform 12. Specifically, fixing element 14 is a fixing buckle, which is used to fix the outer edge of the circuit board 21 on the mounting platform 12. In this embodiment, the precise cooperation between the positioning pin and the positioning groove 212 can quickly and accurately position the circuit board 21 on the mounting platform 12, ensuring high precision in the installation position of the circuit board 21 and providing a stable foundation for the coordinated operation of the encoder and the motor. Precise positioning effectively reduces problems such as unstable signal transmission and data errors that may be caused by deviations in the position of the circuit board 21, improving the accuracy of motor control. The fixing buckle firmly fixes the circuit board 21 on the mounting platform 12, effectively resisting the influence of external forces such as vibration and impact during motor operation, preventing the circuit board 21 from loosening and shifting. This further ensures the stability of the electrical connection between the encoder and the motor, enabling the motor to continuously and stably receive and process signals fed back by the encoder during operation, thereby ensuring the overall stable and reliable operation of the motor.

[0031] See Figures 1-6 As shown, an electric motor includes the encoder mounting mechanism described above. A stator assembly 3 is mounted on a base 1, and an end cover 4 is mounted on one end of the base 1. A rotor housing 5 is mounted on the outer side of the end cover 4, and a rotor assembly 6 is mounted inside the rotor housing 5. The rotor assembly 6 is opposite to the stator assembly 3. This embodiment can accurately acquire the position and speed information of the motor rotor assembly 6. Since the rotor assembly 6 and the stator assembly 3 are positioned opposite each other, they work together to achieve energy conversion and power output of the motor, while the encoder mounting mechanism can monitor the state parameters of the rotor assembly 6 in real time. This allows the motor control system to dynamically adjust the current and magnetic field of the stator assembly 3 based on this precise data, ensuring that the motor maintains efficient and stable operation under various working conditions. This helps improve the reliability of motor operation. By accurately feeding back the motor's operating status, potential abnormalities, such as rotor speed fluctuations and position deviations, can be detected in a timely manner and fed back to the control system. The control system then takes corresponding measures to adjust and correct these issues, preventing motor failures due to abnormal operation and greatly extending the motor's service life.

[0032] The end cover 4 is provided with a cavity 41, and an induction magnetic ring 42 is disposed within the cavity 41. The induction magnetic ring 42 is opposite to the encoder element 22. In this embodiment, the induction magnetic ring 42 and the encoder element 22 are precisely aligned, enabling real-time and accurate acquisition of motor operation data, providing accurate feedback for motor control, and thus ensuring that the motor maintains stable speed and torque output under various operating conditions. This improves the accuracy of motor control. Based on the signal feedback from the induction magnetic ring 42, the encoder element 22 can more finely adjust the motor action, meeting the stringent requirements for motor motion accuracy in different working scenarios. The stable and reliable signal transmission and feedback mechanism reduces the failure rate caused by signal errors during motor operation, extends the service life of the motor, and ensures continuous and stable operation of the motor in complex environments.

[0033] Two end caps 4 are provided, each with a bearing 43, and connected to both ends of the base 1 via the bearings 43. The rotor housing 5 is fixedly connected to both ends of the two end caps 4. Specifically, a tire 51 is mounted on the outside of the rotor housing 5, and the two end caps 4 are used to constrain the two sides of the tire 51 onto the rotor housing 5. In this embodiment, the two end caps 4 are connected to both ends of the base 1 via bearings 43, providing a stable and precise support structure for the motor rotor, effectively reducing radial and axial runout during rotor operation, and ensuring stable and reliable motor operation. The fixed connection between the rotor housing 5 and the end caps 4 makes the entire rotor assembly 6 a tight and rigid whole. The constraint effect of the end caps 4 on the two sides of the tire 51 further ensures the relative positional stability between the tire 51 and the rotor housing 5. Combined with the encoder mounting mechanism, it can accurately monitor the position and speed information of the motor rotor. Because the end caps 4 and related structures ensure stable rotor operation, the data acquired by the encoder is more accurate and reliable, and thus fed back to the motor control system, achieving precise control of the motor's operating state.
