Abstract

A model permitting the simulation of skewed-slot saturated machines associated with nonlinear external circuits is proposed. To take the slot effects into account, the magnetic circuit is modeled through the combined two-dimensional calculations along the machine axis. In this simulation the electric circuit equation is directly coupled with the magnetic one. The solution of the resulting nonlinear time-dependent equation is obtained using step-by-step numerical integration and the Newton-Raphson iterative procedure. The model is used for the simulation of a 4.6-N-m permanent-magnet synchronous machine in various modes of operation
