“…Tooth width, in [17] an experiment with a 36-slots machine is carried out, showing that with closed slots a torque ripple of 13.7% is produced, while for semi-closed slots it is 18% and for open slots 22.4%. A cross-section of a motor with closed slots is shown in Figure 9 (b) [18].…”

This paper aims to evaluate the performance of synchronous reluctance motors assisted by a permanent magnet (PMa-SynRM) focused on efficiency and torque pulsations. PMa-SynRM shows high efficiency and power factor, compared to induction motors (IM), although they have a greater cost. These machines develop relatively high torque ripple, cogging torque, and torque imbalances. Consequently, the electromagnetic torque is reduced, the motor temperature is increased, and mechanical vibrations are induced. The optimal design of the machine structures such as flow barriers, permanent magnets, and stator slots, among others, allow reducing torque pulsations. A comparison is made between different designs of the PMa-SynRM reported in the scientific literature, and the effects on efficiency, torque pulsation, and operating costs are evaluated. A case study on the motor driving the air conditioner blower in a hotel room was made, to determine the best economic variant between IM or PMa-SynRM. A sensitive analysis was made to evaluate several uncertainties. The advantages of using one of the PMa-SynRM analyzed were demonstrated. Also, it was proved that the investment is feasible economically, although NPV and payback are not the best, due to low load factor in inverter-controlled motors in air conditioners.

The growing demand of high-performance motors requires the definition of more accurate design procedures. The only possibility to obtain such kind of results is to combine Finite Element programs with optimization procedures. For this reason, a multi-objective optimization algorithm has been developed, and it has been used to design a Synchronous Reluctance Motor with flux barriers rotor, starting from the stator core of a commercial three-phase induction motor of equivalent size. Based on the optimization results, a prototype has been built and tested.

“…In the existing literature, several different studies on reviewing/ comparing the electromagnetic performance characteristics of different machine technologies can be found [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Different electric machine topologies have been compared and it is concluded that the PM machines, particularly having IPM topologies, are one of the best rotor topologies suitable for the electric vehicle (EV)/hybrid electric vehicle (HEV) and aerospace applications [5,6].…”

“…The influence of winding structure, magnet shape optimisation, using much cheaper rare-earth magnets; such as ferrite, different rotor topologies, flux barrier geometry optimisation etc. on the performance characteristics have also been investigated [7][8][9][10][11][12][13][14][15][16][17][18][19]. It has also shown that the switched reluctance machines namely DSRMs has also potential to be used in the aerospace applications [20][21][22].…”

In this study, the compatibleness/effectiveness of the proposed novel semi-overlapping winding (NSW) topology has been investigated by implementing into different synchronous machine technologies, namely interior permanent-magnet machine, synchronous reluctance machine (SynRM), permanent-magnet assisted SynRM, and double-salient reluctance machine. All considered machines have also been designed with different winding topologies; i.e. integer-slot distributed winding, fractional-slot concentrated winding (FSCW) in order to reveal the merits/demerits of the proposed NSWs. A comprehensive electromagnetic performance comparison has been presented. It has been validated that the proposed winding topology promises significant advantages; such as improved efficiency with substantially reduced total axial length, low eddy permanent magnet (PM) loss and low risk of irreversible magnet demagnetisation over conventional winding topologies. It has also been revealed that the implementation of proposed NSWs into the reluctance machines results with higher torque and power output than that of FSCWs.
