摘要
The subdomain technique has been widely used to predict electromagnetic performance in permanent-magnet (PM) machines. Due to the high accuracy of magnetic field distribution prediction by subdomain technique, a simple method for electromagnetic performance calculation in surface-mounted PM machines with skewing is proposed. By taking the machine with step-skewed magnets as a combination of multi-machines operating with different rotor positions at the same instant, the influence of the axial magnet segments can be considered in 2D subdomain model of surface-mounted PM machines. Based on the magnetic field analytical solution, the cogging torque, back-EMF and electromagnetic torque is calculated, and the 2D multislice finite-element analysis confirms accuracy of the analytical method.
