“…However, their saliency ratios are 1 (or close to 1), so these motors do not provide a sufficient reluctance torque component [14]. Additionally, they are not the most suitable candidates for variable-speed applications due to their low field-weakening capabilities [15].…”

Permanent magnet synchronous motors (PMSMs) are consciously used as traction motors in electric vehicles (EVs) and hybrid electric vehicles (HEVs). The rotor position (inner-rotor, outer-rotor) and topology of PMSMs significantly impact their torque profile, efficiency, and demagnetization characteristics. This article focuses on designing an outer-rotor permanent-magnet-assisted synchronous reluctance motor (PMaSynRM) under traction motor requirements and investigating its electromagnetic performance using the finite element method (FEM). This study's primary challenge is achieving optimal machine performance, considering high maximum torque and the risk of demagnetization at low levels. The design, derived from analytical calculations, was subjected to Finite Element Method (FEM) analyses. These analyses investigated motor performance in terms of efficiency, the ability to generate torque at different drive currents, and the risk of demagnetization. As a result of the study, the proposed PMaSynRM design was obtained that provides an adequate demagnetization performance even under 300% loading, has a maximum torque exceeding 35 Nm, and achieves an efficiency of 90% at rated conditions.

“…Due to their high-power density and other irreplaceable advantages, the surfacemounted permanent magnet (PM) machines (SMPMM) have been applied in many situations i.e., industrial manufacture, home automation, electro-mobile, robotics, etc. [1][2][3][4][5][6]. At present, people pay much attention to the weakening of the cogging torque, to the reduction in torque ripple, and to the suppression of the vibration or noise of the SMPMM [7][8][9][10][11].…”

An analytical method was proposed for obtaining the magnetic field distribution for surface-mounted permanent magnet machines with the structure of unequal magnetic poles. Firstly, the Laplace equation and Poisson equation were solved using the method of the separation of variables, and then the mathematical model of the motor structure with unequal magnetic poles was obtained. Secondly, according to the design parameters of the two types of prototypes motors, the flux density in the air gap region of the two types of prototypes motors was calculated, respectively. Thirdly, by comparing the results calculated using the analytical method with the results obtained using the finite element method, the analytical method proposed in this paper was proven to be effective. Moreover, the armature reaction field and the effect of the stator slotting were considered in the mathematical model as well. Overall, the analytical method presented in this paper provides a theoretical basis for the analytical calculation of motors with the structure of unequal magnetic poles.

“…The main challenging factors for the design of PMSM are the number of permanent magnets used, shape, size, stator winding topologies, and positioning of permanent magnets [20]. The two basic rotor structures of permanent magnet synchronous motor are (i) Surface mounted permanent magnet synchronous motor (SMPMSM) and (ii) Interior buried magnet permanent magnet synchronous motor (IBPMSM), and a comparative analysis of fractional slot type SMPMSM and IBPMSM in terms of induced EMF, torque, losses, and efficiency are presented in [2], [21][22][23]. Also, the comparison is done based on its size, weight of materials used, and electromagnetic characteristics.…”

In this paper, a V-shaped interior buried permanent magnet synchronous motor (VSIBPMSM) is proposed to increase the flux linkage, back emf, torque, power factor, and efficiency by reducing the leakage flux, cogging torque, ripple torque, and core losses. The proposed rotor design focuses on reducing the size of the rib to reduce the reluctance caused by the rotor core. On the stator side, a semicircular dimension type slot is preferred with a double-layer, distributed winding to increase the torque. The width of the stator yoke is optimized to reduce core losses. All the stator slots are skewed to reduce the cogging torque. The performance analysis of the proposed permanent magnet synchronous motor (PMSM) is compared with the surfacemounted PMSM (SMPMSM) in various aspects, and the proposed synchronous motor shows better performance compared with the surface-mounted synchronous motor. The step-by-step mathematical design and analysis of VSIBPMSM are presented, and modeling work is carried out using ANSYS Maxwell software.
