“…In particular, the SRG is mainly applied to vehicles, wind turbines and high-speed equipment because it can be operated in a wide speed range [16]. There are a lot of the literature working on SRG wind generators application [16][17][18], HEVs [19] and battery charging [20]. For example, a control system for the operation of an SRG driven by a variable speed wind turbine has been suggested in [17].…”

Selection of electrical machine is a key issue in electrical and hybrid electrical vehicles (HEVs and EVs). As far as HEVs and EVs are concerned, mechanical ruggedness of electrical machine is of utmost importance. For these reasons, the application of switched reluctance (SR) machine in EVs and HEVs is a viable option. In this study, an SR generator (SRG) has been utilised to work as a battery charger in EVs. The current ripple of the SRG is the greatest issue when it works as a battery charger. Therefore, a power converter and a smart search control (SSC) approach are proposed in this study to decrease the current ripple when the output power has a maximum quantity. During the system operation, the SSC method determines the value of excitation angle, turn-on and turn-off angles for each phase of SRG. The simulation and experimental results demonstrate the eligibility of the SSC system and power converter to obtain the acceptable charging current in maximum generated power during battery charging.

“…The high-power density of the permanent magnet synchronous motors (PMSM) made them popular in the traction application [8,9]. The high cost of the rare-earth magnet materials of the PMSM motives researchers to improve the efficiency and performance of the induction [10], synchronous reluctance [11], and switched reluctance motors [12][13][14]. Nowadays, PMSMs are the main part of the propulsion system of the commercialized EVs whereas some models of Tesla electric car such as Tesla Roadster benefit from the low-cost induction machine in its propulsion system [15].…”

In some applications such as electric vehicles, electric motors should operate in a wide torque and speed ranges. An efficiency map is the contour plot of the maximum efficiency of an electric machine in torque-speed plane. It is used to provide an overview on the performance of an electric machine when operates in different operating points. The electric machine losses in different torque and speed operating points play a prominent role in the efficiency of the machines. In this paper, an overview about the change of various loss components in torque-speed envelope of the electric machines is rendered to show the role and significance of each loss component in a wide range of torque and speeds. The research gaps and future research subjects based on the conducted review are reported. The role and possibility of the utilization of the computational intelligence-based modeling of the losses in improvement of the loss estimation is discussed.
