A Review of Axial-Flux Permanent-Magnet Motors: Topological Structures, Design, Optimization and Control Techniques

Abstract

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.

Simulation Time Reduction with 2.5D FEM Analysis for Axial Flux Machines

“…Gulec and Aydin (2017) limited their investigation to the analysis of a torus-type double-rotor AFM, while Kim and Woo (2022) applied the idea to a single-rotor single-stator topology. Multiple AFM topologies were reviewed by Hao et al (2022). In this article, focus will be placed on two common types of AFMs, namely the single-rotor double-stator I-type topology and the double-rotor single-stator H-type (YASA) topology.…”
