“…By combining the pole-arc coefficients of the single-side rotor, weakening of the amplitude of the cogging torque of the single side can be realized, the combination of which is shown in (12). By combining the pole-arc coefficients of both the inner and outer rotors, the inner and outer cogging torques can be canceled out with each other, the combination of which is shown in (13); thus, further weakening of the overall cogging torque is realized. The mathematical models of inner and outer rotor pole-arc coefficients, eccentric distance, and chamfer angle with the cogging torque of the DRPMSM are established by the response surface method.…”

“…In general, by comprehensively considering the weight, volume, reliability, efficiency, and torque density, PM motors are considered the most advantageous for electric aircraft propulsion [6][7][8]. The propulsion motor has increasingly adopted outer rotor [9][10][11], dual rotor [12], or axial multi-disk rotor [13,14] structures to enhance the action area of permanent magnet and armature winding, thereby improving the torque density of the motor. In this Energies 2024, 17, 1583 2 of 19 paper, a novel dual-rotor radial flux permanent magnet synchronous motor (DRPMSM) is proposed to achieve the goal of high torque density.…”

The direct-drive type high-torque-density motor is one of the most promising solutions of electric propulsion for aircraft. The cogging torque of the direct-drive motor causes torque ripple, vibration, and noise, which seriously affect the stability and reliability of the electric propulsion system for aircraft. In this paper, a novel direct-drive type high-torque-density dual-rotor radial flux permanent magnet synchronous motor (DRPMSM) is proposed, and its cogging torque is weakened by permanent magnet shape design and pole-arc coefficient combination. An eccentric and chamfered permanent magnet shape is proposed, and the influence of eccentric distance and chamfer angle on cogging torque is clarified. Through the pole-arc coefficient combination design of the inner and outer rotors of the DRPMSM, the cogging torques of the inner and outer rotor are phase reversed, thus further reducing the total cogging torque of the DRPMSM. By employing the response surface method, a mathematical model is established for the cogging torque of the DRPMSM in relation to the pole-arc coefficients, chamfer angle, and eccentric distance of the permanent magnets. The parameters that minimize the cogging torque of the DRPMSM are obtained using a genetic algorithm. A prototype is manufactured according to the optimized parameters, and experimental results validate the correctness of the theoretical analysis and the effectiveness of the optimization design method.

Flux switching machines play a crucial role in emerging sectors such as renewable energy, electric vehicles, and the aerospace industry. Recent advancements have underscored their potential for achieving high torque density, effective heat management, and flux-weakening capabilities. This paper provides a comprehensive review of the design optimization of these machines, offering a unique contribution, as no previous attempts have delved into a detailed exploration of various optimization techniques specific to this technology. Special attention is given to state-of-the-art technologies related to multi-objective optimization and the performance analysis of the three variants: permanent magnet, wound-field, and hybrid excited. The review highlights and compares several optimization strategies from recent research, revealing research gaps in integrating advanced control algorithms, thermal, vibroacoustic, and structural models into the optimization design process of these machines. Furthermore, this review identifies essential trends in optimization development, offering valuable insights and future perspectives for these machines across diverse applications.
