Analytical Magnetic Field Calculation of Vernier Permanent-magnet Machines Based on Accurate Subdomain Model
摘要
Abstract
Vernier permanent-magnet machines are novel magnetic force transmission devices, and are becoming promising candidate for low-speed high-torque applications such as ship propulsion and wind power generation. Accurate calculation of the magnetic field is a key to design and optimize vernier permanent-magnet machines. The one slot per pole machine model and the accurate subdomain model are discussed and compared. The Laplace's equations in the airgap subdomain, Poisson's equations in the permanent magnet subdomain and the slot subdomain are solved by the variable separation method. The analytical model is set up in 2D polar coordinates and accounts for the influence of radial/parallel/Halbach magnetization, single/double layer winding configurations, internal/external rotor topologies, which can be used to predict the open-circuit, armature reaction and on-load magnetic field distribution. Based on this field model, the electromagnetic performances, such as the airgap magnetic field density, back-EMF and winding inductances is calculated. The analytical model is validated by the corresponding finite-element results.关键词
