Analytical Calculation of Open-Circuit Field in Surface-Mounted Permanent-Magnet Machines Accounting for Slots in Stator and Rotor
摘要
Abstract
An analytical method for calculating the open-circuit field distribution in the surface-mounted permanent magnet machines accounting for slots in stator and rotor was presented. Open-circuit field produced by radial and parallel permanent magnet was equivalent to that produced by surface current according to equivalent surface-current method of permanent magnet. The model was divided into three types of subdomains. Then the field solution of each subdomain was obtained by applying the interface and boundary conditions. Finally, the open-circuit field produced by equivalent surface current was superposed according to superposition principle of vector potential. The prototype machine with 4-poles/24-stator slots/20-rotor slots is used for validation. The finite element (FE) results confirm the validity of the analytical results with the proposed model.关键词
