Abstract

A rotary magnetic actuator of highly three-dimensional geometry is analyzed by the finite-element method. A one-quarter model composed of three-dimensional finite elements is developed for analysis by the vector potential Newton-Raphson approach. The nonlinear saturable magnetic fields, fluxes, inductances, energies, and torques are calculated at three armature positions. The calculated torques compare reasonably well with measurements
