Abstract

An analysis of variations of innovative design for double-sided inner-coreless-stator axial-flux permanent-magnet (AFPM) generators intended for micro-wind turbine applications is presented in this paper. The 3-D finite-element field analysis proves that design variations of ironless stator with non-overlapping concentrated winding, sandwiched between two opposing steel rotor disks with embedded circumferentially-magnetized ferrite permanent magnets (PMs) in flux-concentration arrangement, may represent good-performance and cost-effective double-sided topologies for AFPM machines in micro-wind power generation applications.
