Influence Analysis of the Geometry and Materials For the Electromagnetic Torque Calculation on a Stepper Motor

This paper aims to present the design of a hybrid-stepper motor by considering two variants from the geometry and material point of view. Numerical simulation is used in the design stages, which helps reach specific performances. The current study approaches the influence of the geometry and materials for the detent and holding torque calculation on a hybrid stepper motor. There are two models, and for each one, numerical analysis is used to calculate the detent and the holding torque versus angle characteristics, and by this, fulfilling the motor requirements towards its applications.
