Abstract :

In recent years, metropolises around the world have seen a declining trend in the air quality index. Much of this pollution is related to public transportation. Upgrading public transportation can be a way out of this impasse. Due to environmental concerns, it is recommended to switch from conventional diesel buses to electric buses, which have several benefits in terms of reducing pollution, noise and fuel. In this paper, a high power induction switched reluctance motor used in a city electric bus is studied. The stator and rotor structure of this electric car is non-segmental. The structure is such that a short magnetic flux path is created in the rotor and stator core. As a result, high torque is produced with low losses. Since the electric motor has a very high power, it therefore requires a large amount of permanent magnets, so it is desirable that the electric motor in the electric bus does not have a permanent magnet. Here is a three-phase induction switched reluctance motor with a power of 220 kW, with 6 stator poles and 4 rotor poles. A two-dimensional finite element model is designed and its magnetic analysis is performed. The flux path, torque and efficiency of the induction switched reluctance motor are calculated and the results are presented.
