“…A constant velocity joint is located at each end of the driveshafts to compensate the relative motion between the differential and wheel [150,151]. The efficiency of the drive shaft, which is dependent on the constant velocity joints (i.e., tripod and Rzeppa), is obtained by (11).…”

“…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.

“…Research conducted on the subject has led to the development of several SynRM rotor designs starting from adapted IM rotor laminations to the single or multi-flux barriers topologies [27,34]. In addition to the radial flux rotor designs, an axial fluxSynRM concept has also been proposed [24,33]. To design the new SynRM rotor structures, researchers initially used a simplified mathematical analysis [18,43].…”

The aim of this study was to investigate and analyse the synchronous reluctance machine. An accurate method for determining the lumped parameters of an equivalent circuit of the studied machine has been proposed. The method is based on the phase currents and voltages analysis at low slip operation. Experimental research of a synchronous reluctance machine is supplemented by simulation studies. The field-circuit model of electromagnetic phenomena in the considered motor was developed and used in simulation. The proposed method allows the numerical model to be verified by comparing the calculated and measured torqueangle characteristics of the machine. The test results obtained are presented and discussed. Achieved satisfactory concordance between simulation and experiment results proves that the proposed approach can be useful in the synthesis of reliable synchronous reluctance machines as well as in their control systems.
