Abstract

The article presents the results of a numerical study and comparative analysis of traction electric drives for urban trolleybuses based on induction motors and synchronous permanent magnet motors, as well as a combination of high-speed permanent magnet motors and magnetic reducers. It is shown that the replacement of short-circuited rotor with a permanent magnet rotor in a standard induction motor can significantly increase the specific power of the electric machine. Numerical studies and analysis of the characteristics of an electric motor with neodymium magnets for four configurations of the rotor magnetic system have been carried out and the optimal one in terms of specific performance has been determined. It is established that in order to ensure maximum specific characteristics in traction electric motors, it is necessary to take into account the peculiarities of the driving cycle and use liquid cooling. The results of thermal calculations taking into account the driving cycle showed that the use of liquid cooling ensures that the temperature of neodymium magnets and windings is maintained below critical values even at loads close to the limit. Additionally, the possibility of reducing the size and weight of the electric drive by using a high-speed motor with a magnetic gearbox was considered. Calculations of electromagnetic and thermal characteristics were performed in the Simcenter Magnet and Simcenter MotorSolve software packages. References 9, figures 9, tables 3.
