[Abstract]:The design method of high efficiency and super high efficiency asynchronous motor with cast copper rotor technology instead of traditional cast aluminum rotor is a hot spot in the research field of motor energy saving system. Aiming at the electromagnetic and thermal design of the induction motor with cast copper rotor, this paper firstly summarizes the research status of electromagnetic design method of the asynchronous motor with cast copper rotor at home and abroad, and summarizes the relevant data of the temperature field research of the asynchronous motor. Secondly, the application advantage of low harmonic winding technology in cast copper rotor asynchronous motor is discussed, and the effect of different rotor casting materials on the motor performance is compared and analyzed, thus the basic electromagnetic scheme of the motor is determined. Aiming at the problem of weak starting performance of cast copper rotor asynchronous motor, the effects of two different rotor groove shape parameters on motor starting performance are compared and analyzed, and the starting performance of cast copper rotor asynchronous motor is optimized. Considering the sensitivity of motor efficiency to motor temperature and the complexity of analysis and calculation of motor temperature field, the basic principle, basic model and application method of space equivalent heat path method are summarized in this paper. The loss of the main electromagnetic components of the motor is calculated based on the finite element method. At the same time, the steady-state and transient temperature distributions of the induction motor with cast copper rotor are calculated by using the equivalent heat path method, and the parameters of the main heat dissipation structure of the motor are parameterized to optimize the heat dissipation performance of the motor. The heat dissipation of the motor is improved. Finally, the experimental prototype was manufactured and the prototype was preliminarily tested. The test results show that the design method presented in this paper has a high precision and meets the practical engineering requirements, and the performance parameters of the motor are up to the relevant requirements of the high efficiency asynchronous motor standard, and good results have been obtained. The research work carried out in this paper has important reference value for the design and research of high efficiency asynchronous motor.
