“…Although the rotor design parameters discussed to determine the greatest reduction in torque ripple in PMa-SynRM, the stator design is also important. In [25], a design is developed using a FEM software to obtain the best stator parameters, from a test motor of 1.62 A, 563 rpm, 1.2 Nm, 4 poles, 24 slots, 3 flux barriers per pole, and values of kq = 0.9 and kd = 1.0. The rotor structure remains constant.…”

“…In [25] the use of 6 slots/4 poles and 12 slots/4 poles with concentrated windings, was evaluated. It was obtained that, for 6 slots, the average torque was 1.8 Nm and torque ripple 44%, while, for 12 slots, the values were 0.578 Nm and 43.25%, respectively.…”

“…The second layer of the last winding has a fractional coil pitch. The average torque, the torque ripple, and its percentage for each winding are given in Table 6 [25]. The double-layer suppresses the odd 5th, 7th, 11th, 13th harmonics.…”

“…In [25], the slot's geometric optimization is performed. The slot shape, the height of its opening, the tooth bottom rounding, and the wedge height, practically do not at all affect the results, while the slot opening width and the tooth width affect them significantly.…”

“…The slot shape, the height of its opening, the tooth bottom rounding, and the wedge height, practically do not at all affect the results, while the slot opening width and the tooth width affect them significantly. The optimization method used in this study can be seen in [25]. The most relevant results on the slot opening and tooth width are described below.…”

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.
