摘　　要：基于大功率直线推进的要求,设计短时周期工作的直线感应电机。提出了基于热网络法,计及端部绕组热传导、复合材料影响的直线电机温度场计算方法,推导了周期暂态工作的直线电机温度场热网络模型,得到了该直线电机线圈导体准确的温度变化规律。基于数学模型建立了仿真模型,对电机散热性能进行了仿真计算,为该直线感应电动机的设计和性能分析提供了重要参考。Based on the requirement of high-power linear propulsion system, the short-time periodic linear induction motor （ LIM） needs to be designed. Based on thermal network, taking into account the end-winding and the effects of thermal conduction composite materials, the calculation method of the linear induction motor temperature field was proposed. The thermal network model of the temperature field of the periodic transient LIM was deduced. The rule of the LIM coil temperature change was obtained accurately. The simulation model was established based on the mathematical model, and then the performance of the motor thermal dissipation was simulated, which provided an important reference for the design and performance analysis of the linear induction motor.
