Opis:: A special type of a two-phase permanent magnet stepper motor with asymmetric stator was constructed for the specific purpose. The structural design was based on a modified geometry of standard stator and a functional motor prototype was built. The measurement of the step uniformity reveals irregular step size for half-stepping driver. This paper presents the approach to find proper stator pole dimensions to achieve uniform step in half-stepping regime of permanent magnet stepper motor. The simulation of a magnetic circuit was used. The measurement on the prototype and the simulation of the motor angle for different stator arrangement are presented.

Opis:: This research presents a method of modeling and numerical simulation of a reluctance stepper motor using reduced finite-element time-stepping technique. In presented model, the circuit equations are reduced to non-stationary differential equations, i.e. the inductance mapping technique is used to find relationship between coil inductance and rotor position. A strongly coupled field-circuit model of the stepper motor is presented. In analyzed model the magnetostatic field partial differential equations are coupled with rotor motion equation and solved simultaneously in each iterative step. The nonlinearity problem is solved using Newton-Raphson method with spline approximation of the B-H curve.
