“…A winding structure called "drum winding" surrounds the stator in the radial and circumferential directions, as shown in Figure 2(a). Drum windings can be either non-overlapping or overlapping [16]. These coils are evenly distributed along the diameter of the stator core in the opposite position such that each phase has an equal number of oppositely connected coils to eliminate the magnetic flux circulation that may occur in the stator core [17].…”

“…Toroidal windings surround the stator in the radial and axial directions and are always non-overlapping, as shown in Figure 2(b). Nonoverlapping windings simplify the winding assembly but affect the output torque to a certain extent owing to their small winding factor [16]. When toroidal windings are used in torus motors, as shown in Figure 3, radial windings are used to generate torque to maximize the active portions of the windings, resulting in relatively short end windings.…”

Axial flux permanent magnet synchronous motors (AFPMSMs) have been widely used in wind-power generation, electric vehicles, aircraft, and other renewable-energy applications owing to their high power density, operating efficiency, and integrability. To facilitate comprehensive research on AFPMSM, this article reviews the developments in the research on the design and control optimization of AFPMSMs. First, the basic topologies of AFPMSMs are introduced and classified. Second, the key points of the design optimization of core and coreless AFPMSMs are summarized from the aspects of parameter design, structure design, and material optimization. Third, because efficiency improvement is an issue that needs to be addressed when AFPMSMs are applied to electric or other vehicles, the development status of efficiency-optimization control strategies is reviewed. Moreover, control strategies proposed to suppress torque ripple caused by the small inductance of disc coreless permanent magnet synchronous motors (DCPMSMs) are summarized. An overview of the rotor-synchronization control strategies for disc contra-rotating permanent magnet synchronous motors (CRPMSMs) is presented. Finally, the current difficulties and development trends revealed in this review are discussed.
