...-disc rotor design are presented. Then, the permanent magnet hysteresis motor with single-disc rotor has been precisely simulated by finite element method using the Preisach model (for modeling semi-hard material). Subsequently, the diameters of the permanent magnet and semi-hard material have been...

...Sajid Hussain; David Lowther Purpose The losses incurred in ferromagnetic materials under PWM excitations must be predicted accurately to optimize the design of modern electrical machines. The purpose of this paper is to employ mathematical hysteresis models (i.e. classical Preisach model...

... with a static Preisach hysteresis model. The Preisach model was validated by comparing it with measurements obtained from an Epstein frame. Then, the results obtained with this approach were compared with a basic analytical method that is widely used. Findings The authors' model provides a fast way...
