“…Therefore, the torque performance can be improved. It is demonstrated that the maximum output torque of a conventional CP-PMSM can be obtained by optimizing the PM-arc ratio [23] [24]. It can be seen that the machine can obtain the maximum output torque at αp = 0.68 and the minimum torque ripple at αp = 0.5; this is due to the increase in air-gap flux density asymmetry when αp > 0.5, which is concluded based on the principle that the same flux flows through the PM and iron pole of the CP-PMSM (Φpm = Φip) [25].…”

This paper proposes a novel low-cost consequent-pole permanent magnet (CPM) synchronous machine structure, considering the reluctance torque utilization. First, a novel CPM machine with doubled salient ferromagnetic iron poles (ICP-PMSM) is proposed, featuring an N pole-ironS pole-iron sequence to maximize the reluctance torque utilization and reduce cost. Flux barriers are integrated into the rotor structure to maintain the same magnetic rotor pole number as the conventional CPM synchronous machine (CP-PMSM). Second, for a low torque ripple, soft ferrite is used to replace part of the iron pole in the ICP-PMSM (ISCP-PMSM) to improve the air-gap flux density distribution. Furthermore, the CP-PMSM, ICP-SPMSM, and ISCP-PMSM rotors are optimized for a fair comparison. The electromagnetic performances of all the optimized machines are compared with those of a conventional surface permanent magnet synchronous machine (SPMSM). It is demonstrated that the ISCP-PMSM can obtain an almost equivalent torque and torque ripple, but with reduced PM (NdFeB) usage and cost when compared to the SPMSM.

“…By separating the armature winding and stationary PMs, the space for the PM and armature winding increases, the motor copper losses decrease, heat is easily dissipated, PMs are kept away from the winding high-temperature zone, and the risk of the PM demagnetization is reduced. Consequently, PS-FRPMM compared with the conventional FRM and conventional PM machines, shows better performance and higher torque density per copper losses [1,2], [6,7], [11][12][13][14][15][16][17].

 Abstract-A Partitioned Stator-Flux Reversal Permanent Magnet Machine (PS-FRPMM) is a new combination of a stator PM machine and a magnetically geared machine and has the specifications of both machines in terms of robust structure and torque density. In this paper a comprehensive 2-D analytical model is developed for PS-FRPMM based on subdomain technique. The presented model has the capability to accurately and quickly investigate the effects of design parameters on the machine performance. The 2-D analytical model is evaluated on two case studies with 12 stator teeth and 10 rotor poles, and 18 stator teeth and 13 rotor poles, with four different magnetization patterns. The influences of various design parameters such as the rotor slot width, slot opening width and the segment ratio of the PMs in the 2-segment magnetization pattern have been investigated on the quantities such as the instantaneous torque, torque ripple, Unbalanced Magnetic Force (UMF) and Electromotive Force (EMF). For evaluating the presented analytical model, 2-D Finite Element Method (FEM) with and without saturation effects has been used. The comparative study between the analytical and numerical models shows good agreement. Finally, a 3-D FEM has been used and the results of 2-D analytical model and 3-D FEM are compared in term of the accuracy and computational time. The results show that the presented model has lower computational time compared to the 2-D and 3-D FE method, while its accuracy is acceptable under different circumstances such as saturation.

“…Partitioned stator permanent magnet (PS-PM) machines have recently been introduced to tackle the compromising between electrical and magnetic loadings in conventional double salient permanent magnet (DSPM) machines, such as switched flux permanent magnet (SFPM) machines and flux reversal permanent magnet (FRPM) machines [1]- [4]. It is worth mentioning that PS-PM machines have been designed with rotary and linear configurations [5]- [10].…”

In this study, partitioned stator permanent magnet (PS-PM) tubular machines having single- and double-layer windings layouts have been investigated. Two configurations of PS-PM tubular machines were considered, i.e. partitioned stator surface mounted permanent magnet (PS-SPM) and interior permanent magnet (PS-IPM) tubular machines. A comprehensive comparison has been carried out in order to investigate the impact of the winding layouts on such machines. It should be mentioned that the FE package that is used in this paper is (ANSYS Maxwell). It has been noted that irrespective of machines configurations, i.e. either PS-SPM or PS-IPM tubular machines, similar thrust force capability, higher average thrust force per magnet volume, lower thrust force ripple as well as cogging force and higher fault tolerance capability can be delivered by PS-PM tubular machines with single-layer winding compared to that with double-layer winding.
