Аннотация
In the article proposes a method for estimating the thermal state of an asynchronous traction motor. A block diagram of a thermal model of an asynchronous traction motor is presented in which the stator and rotor are modeled as concentric rotating cylinders. The convection heat exchange between two rotating cylinders is represented by modeling an air gap with an effective thermal conductivity that takes into account both thermal conductivity and convection.
