Dynamical model of motor winding temperature

The invention provides a kinetic model of motor winding temperature. An electric drive system includes a permanent magnet synchronous motor. A stator of the motor has a winding which is temperature-limited. Winding temperatures in the central section and at the ends of the winding are estimated using a kinetic model. The inputs of these kinetic models include rotor speed, winding current, engine oil flow rate, sump temperature, and ambient temperature. Empirical constants in the model are set based on vehicle testing. 本公开提供了"马达绕组温度的动力学模型"。一种电驱动系统包括永磁同步马达。所述马达的定子具有绕组，所述绕组受到温度限制。使用动力学模型估计绕组的中心部段中和端部处的绕组温度。这些动力学模型的输入包括转子转速、绕组电流、机油流速、油底壳温度和环境温度。基于车辆测试来设置模型中的经验常数。
