For example, the motor temperature alarm threshold is set to be 10 DEG C lower than the rated maximum temperature. In the experiment, when the motor body 1 is overloaded or poorly cooled and the temperature gradually rises and approaches the alarm threshold, the fan body 11 of the utility model can timely send sound and light alarm. After receiving the alarm signal, the operator can immediately take measures, such as reducing the load or checking the cooling system. The traditional fan often cannot be found until the temperature of the motor body 1 exceeds the rated value and causes certain damage due to the lack of real-time monitoring and alarm function. After long-term operation test comparison, the average service life of the motor body 1 using the fan body 11 of the utility model is prolonged by about 30% compared with the traditional fan, which effectively reduces the equipment maintenance and replacement cost of enterprises due to frequent damage of the motor, improves the overall use efficiency of the equipment, and also helps to maintain the continuity and stability of the production process, reduces the impact of equipment sudden failure on production plan and product delivery.

[0027] The unique design of the layout of various sensors at specific key positions (stator winding, rotor magnetic steel, etc.) in the motor body 1 includes the selection of sensors, installation position and method, and stable and efficient electrical connection between the sensors and the microprocessor. This design ensures that the key operating parameters of the motor body 1 can be accurately collected, and the data transmission is smooth.

[0028] The motor body 1 shell is made of high-strength aluminum alloy material with good heat dissipation performance, and is designed with a specific shape and layout of heat dissipation fin structure. This shell design not only provides reliable protection for the internal components of the motor body 1, but also greatly improves the heat dissipation efficiency, which is an important part of ensuring the stable operation of the motor body 1. The material and structure parameters and design ideas of the heat dissipation fin can be used as protection points;

[0029] The processing algorithm of the microprocessor body 6 for sensor data collection includes data integration, preliminary analysis, and how to filter and judge the data according to the preset logic, such as determining the effective range of data, identifying and marking abnormal data, and other processing processes;

[0030] The setting method and logic of the preset alarm threshold, the alarm threshold determined based on the design specifications, rated parameters and safety margins of the motor body 1 for different parameters such as temperature, rotating speed and torque, and the control logic and circuit design of the microprocessor body 6 for triggering the sound and light alarm signal when the parameters exceed the threshold, including the connection and driving mode of the sound and light alarm device and the microprocessor body 6;

[0031] The communication module design between the microprocessor body 6 and the background port, covering the wireless communication module (including the wireless communication protocol, frequency band, signal enhancement technology, etc. adopted) and the wired network interface (interface type, data transmission rate, anti-interference design, etc.), as well as the logic and control mechanism for intelligent switching between the two, to ensure the stability and continuity of data transmission in different communication environments;

[0033] Working principle: When the operator uses the device, first connect an external power supply to the device to provide power support. By installing high-precision temperature sensors 3, rotating speed sensors 2 and torque sensors 4 at key parts of the motor body 1 (stator winding, rotor magnet, etc.) and connecting them to the microprocessor body 6, the real-time and accurate acquisition of key operating parameters of the motor body 1 is successfully achieved. This improvement overcomes the defect of traditional fan bodies 11 that are difficult to obtain real-time parameters such as rotating speed, torque and temperature of the motor body 1, so that the microprocessor body 6 and the background port can transmit data through the wireless communication module (in good wireless communication environment) or use the wired network interface (when the wireless communication environment is poor) for data transmission. In the experimental environment simulation, when the wireless communication is strongly interfered (such as within 5 meters of multiple high-power wireless devices), the traditional fan will have data transmission interruption, delay or error, etc., resulting in the monitoring terminal being unable to obtain the motor body 1 parameters in real time and accurately. When the temperature of the motor body 1 gradually rises and approaches the alarm threshold due to overload or poor heat dissipation, the fan body 11 of the utility model can timely issue a sound and light alarm. The operator can take immediate action after receiving the alarm signal. The above is all the working principles of the utility model.
