“…Di Gerlando et al studied and optimized the size of YASA-type AFPM motor to further reduce the additional power loss and improve the working efficiency of the motor [39]. Xu et al investigated and optimized the cogging torque of the YASA motor with SMC core [40]. Concretely, the structure of YASA motor was with 10 poles and 12 slots, and the stator cores were made of SMC material, while the rotors were made of solid magnetic material.…”

Axial-flux permanent-magnet (AFPM) motors are a kind of important motor with compact structure, high power density and high torque density. In this review, the progress of AFPM motors and their key technologies are analyzed and described, with emphasis on the topological structures, design and optimization methods and control techniques. Based on these analyses, the main findings of the review are the following: (1) the yokeless and segment armature (YASA)-type motors have great potential for development; (2) the multi-objective optimization design theories can be integrated and applied to optimize the design of AFPM motors; and (3) optimal control and sensorless control have important value in improving system reliability and reducing cost. Finally, highlights and prospects are provided for further advancing AFPM motors.

“…The stator shoe width determines the width of the stator slot, thereby affecting the variation of air-gap permeance, and thus the cogging torque and flux leakage. The two parameters of a SMC-based YASA motor are analysed in [60] with respect to the cogging torque and open-circuit back-EMF. A minimum cogging torque is achieved by a proper adjustment of the magnet pole-arc ratio and stator shoe width, with no penalty on the rated torque.…”

“…The response surface analysis is an experiment-based optimization method, which can express the response of the system in the form of mathematical model through specific experimental design and analysis of experimental results [18], and then through analyzing the mathematical model, optimization in the design can be achieved. In this paper, the power density of the motor is the "response" in the response surface model and the thickness of the stator yoke, the thickness of the rotor yoke and relative magnet span are three factors in the response surface model.…”

Surface-mounted permanent magnet synchronous motors (SMPMSM) with high power density and good speed regulation are widely used in industrial applications. In order to further improve its power density, this paper studied the relationship between the thickness of the stator yoke, the thickness of the rotor yoke, the relative magnet span of the motor and the motor power density using the finite element simulation method. On this basis, a response surface model between the three parameters and the power density of the motor was established. Based on this model and a differential evolution algorithm, the motor was optimized and the power density was improve; finally, the optimization results were verified using the finite element simulation method. In addition, the optimization results showed that, when other structure parameters remain unchanged, there is an optimal combination of parameters that can maximize the motor’s power density, including the thickness of the stator yoke, the thickness of the rotor yoke and relative magnet span of the motor.
