Use of Energetic Methods for the Optimized Design of Hybrid Stepping Motors

The modelling used in the study of stepping motors is largely concentrated on the analysis of the motor operation. Effectively, the complex electromag¬netic structure of these machines, particularly of hybrid motors, has hitherto limited the development of modelling methodologies with direct design orien¬tation. The present paper shows the application of an energy-based method to the synthetic evaluation of the components of the holding torque. The use of this method is found to be a real help in the design stage. Some examples of the application of this method are shown, demonstrating its suitability for employ¬ment in tbc optimized design.
