“…The LCM and K w indices of all the possible (S, R) combinations that can satisfy (2) are listed in Table 2. Obviously, the two slot-pole combinations of (18,16) and (18,20) will offer the highest winding factors (K w = 0.945) with different LCMs. By considering the construction convenience within limited physical dimensions, the (S, R) combination with less rotor poles of 16 was selected.…”

“…From the specified operational objectives and physical constraints, many optimisation schemes can be adopted for obtaining the appropriate PM motor parameters [16][17][18][19][20]. Based on their specific features and the selected design variables, by fixing the external diameter, the air gap, the rated operational voltage and current, the three PM motors are, respectively, optimised for achieving the desired mobility-assistive operations on the exoskeleton.…”

Demands of appropriate personal mobility‐assistive devices for those needed persons have been increased considerably in recent years, with their specific operational requirements, developments of adequate motors to different device parts are the main concerns. For applications onto those knee joint parts of the exoskeleton system, three types of permanent‐magnet (PM) motors, namely the surface‐mounted PM motor, the Vernier motor, and the flux‐switching motor were designed. Based on the operational and physical constraints of the particular exoskeleton parts, optimisations of these PM motors were provided along with their thorough performance comparisons. From emulated finite‐element analyses along with hardware experimental validations, by following the standard test settings, selection guidance for the suitable motor structures at different operational objectives will thus be supplied.

“…Finally, the finite element method and analytical formula are used to calculate and analyze the influence of the tooth chamfering method on the electromagnetic vibration and noise of the motor. Jafarboland and Farahabadi [4] optimized the stator yoke thickness (D) and slot angle (A) related parameters of the stator slot to maximize the stator natural frequency without changing the slot area and stator outer diameter. In terms of stator slot inclination, a lot of research has been done.…”

The electromagnetic vibration noise level of a permanent magnet synchronous motor (PMSM) directly affects the Noise, Vibration, and Harshness (NVH) performance of an electric vehicle. Taking a PMSM for electric vehicle driving as an example, the electromagnetic noise characteristics were studied by combining ANSYS Workbench multi-physical field finite element analysis platform. The electromagnetic vibration force of the stator teeth of the motor is the main source of electromagnetic noise. The magnetic field of the motor can be optimized by changing the slot structure of the motor rotor, so as to improve the electromagnetic vibration force of the stator teeth and reduce the electromagnetic vibration noise of the motor. In order to optimize the magnetic field, three different rotor slot structures are proposed. The most suitable slot structure is found by comparing and analyzing the magnetic field, noise field, and electromagnetic force with the structure before optimization. By comparing the results before and after optimization, it can be seen that the optimized motor can effectively reduce the vibration noise of the motor and ensure the electromagnetic performance of the motor.

“…For example, in Ref. [6], some parameters relating to the stator slot are optimised to make modal frequencies of the stator reach the highest value. Since the amplitude of radial force with a large frequency is relatively small, it can lead to weakening or eliminate the influence of structural resonance, so as to reduce the noise.…”

This study proposes a method to reduce the electromagnetic noise of a double-layer interior permanent magnet synchronous motor (DIPMSM) by optimising the flux barrier. First, a noise prediction model of the 36-slot/8-pole DIPMSM is established by finite element (FE). According to the simulation results, the noise of the motor is the loudest at 5000 rpm, especially with a noise component of 3333.3 Hz. From the results of modal analysis, it can be concluded that the four-order radial force with a frequency of 3333.3 Hz resonates with the stator, resulting in the loudest noise. Then, the source of the radial force that causes the loudest noise is analysed, and it can be found that the 9th and 11th harmonics of rotor magnetic motive force have the greatest contribution to the force. By optimising the rotor, the radial force contributed by the 9th and 11th harmonics is weakened, thereby reducing the noise caused by these harmonics. Finally, the electromagnetic performance and noise of the optimised motor are checked by FE. Compared with the initial rotor, the torque ripple is reduced by 26.79%, and noise is reduced by 5.542 dB. The noise test on the prototype verifies the accuracy of the noise prediction model.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.
