Description

Technical Field

[0001] The invention relates to the field of motor production, in particular to a temperature detection device and a detection method for the surface of a permanent magnet synchronous motor of an automobile. Background Art

[0002] Permanent magnet synchronous motors have the advantages of simple structure, small size, high efficiency, high power factor, etc. At present, permanent magnet synchronous motors have been used in medium and low voltage motors in the metallurgical industry (ironmaking plants and sintering plants, etc.), ceramic industry (ball mills), rubber industry (internal mixers), petroleum industry (pumping units), textile industry (twisters, spinning machines) and other industries, and have gradually accumulated design and operation experience;

[0003] The permanent magnet synchronous motor is mainly composed of various parts such as the rotor, end cover and stator. The stator structure of the permanent magnet synchronous motor is very similar to that of the ordinary induction motor. The biggest difference between the rotor structure and the asynchronous motor is that high-quality permanent magnet poles are placed on the rotor. According to the different positions of the permanent magnets on the rotor, the permanent magnet synchronous motor is usually divided into a surface rotor structure and an internal rotor structure. It has low loss and low temperature rise. Since the magnetic field of the permanent magnet synchronous motor is generated by the permanent magnet, the excitation loss caused by the magnetic field generated by the excitation current, that is, the copper loss, is avoided; the rotor runs without current, which significantly reduces the temperature rise of the motor. Under the same load, the temperature rise is more than 20K lower, and the power factor is high. The permanent magnet synchronous motor has a high power factor and is independent of the motor stage. The power factor is close to 1 when the motor is fully loaded. In this way, compared with the asynchronous motor, the motor current is smaller, and the stator copper loss of the motor is correspondingly smaller, and the efficiency is higher. As the number of motor stages increases, the power factor of the asynchronous motor becomes lower and lower. Moreover, because the permanent magnet synchronous motor has a high power factor, the capacity of the power supply (transformer) supporting the motor can be reduced in theory, and the specifications of the supporting switchgear and cables can be reduced at the same time, and the efficiency is high. Compared with asynchronous motors, the efficiency value of permanent magnet synchronous motors is much higher when lightly loaded, and its high-efficiency operation range is wide. The efficiency is greater than 90% in the range of 25% to 120%. The rated efficiency of permanent magnet synchronous motors can reach the current national standard 1 energy efficiency requirements, which is its biggest advantage in energy saving compared with asynchronous motors. Permanent magnet synchronous motors also have the advantages of high starting torque, short starting time, and high overload capacity. The installed capacity of the equipment drive motor can be reduced according to the actual shaft power, saving energy and reducing the investment in fixed assets. Therefore, the existing automobile motors mostly use permanent magnet synchronous motors. Because the permanent magnet synchronous motors of automobiles are mostly placed in the engine compartment of the automobile, the heat generation of the motor is very important. When some motors are assembled, if there are assembly problems, the surface temperature of the motor will be too high when it is used. Such motors are easy to threaten the moving car. In view of this situation, a temperature detection device and a detection method for the surface of an automobile permanent magnet synchronous motor are proposed. Summary of the invention
