abstract

  • In this paper, an advanced control technique to maximize power density of the brushless DC (BLDC) motor/generator system in electric vehicles (EVs) and hybrid electric vehicles (HEVs). For vehicle applications, reducing size and weight of the electric motor/generator system means higher fuel efficiency. Therefore, maximizing power density of the motor/generator system is one of the most important issues in EVs and HEVs. This paper presents the optimal control scheme to maximize power density and minimize machine size and weight for non-sinusoidal permanent magnet machines. The proposed approach can be applied to standard three phase machines as well as multi-phase machines. Fundamental theory of the proposed method is presented and the performance is demonstrated by simulations and experiments.
