The electric motor is a key drive component in the electric vehicle (EV). The switched reluctance motor (SRM) has many advantages, such as compact structure, light weight, high power density, wide speed-tuning range, and low cost, which has made it a priority as the EV drive system. However, its characters of intensive vibration, high noise level, and high temperature hinder its applications in EVs. This research will study: the coupling principle of temperature field and noise field in SRMs, the deterioration of the energy efficiency and the precision of controlling SRM with temperature field and noise filed changing, the heat-noise decoupling and suppressing in SRMs, the methodology of optimizing the SRM structure design, the robust controlling algorithms for dynamic conditions due to multiple current phases and multiple different physical fields, and the improvement of controlling stability and system efficiency, of which the principles and analytical models can provide optimized parameters of SRM structure design and control strategy, and will be applied to electric buses for validation.
