Abstract
In this paper the parameters of a two-phase permanent magnet brushless motor are obtained by using two-dimensional finite element method (FEM). These parameters are the induced EMF in the stator windings, mutual and self inductances of windings, and the static torque developed by the motor. A nonlinear model for motor has been developed in order to predict the transient and steady-state operation of the machine. This nonlinear model has been combined with the model of the drive circuit having two closed loops. The outer loop is the speed feedback with a proportional-integral (PI) type of controller and the inner loop is the current feedback with a hysteresis current control.
