Implementation of a Moving Band Solver for Finite Element Analysis of Electrical Machines
نویسنده
چکیده
The simulation of magnetically geared electrical machines using the finite element method is an especially demanding task when movement has to be considered. Several methods that facilitate movement exist and the most prominent ones are described in this paper. Based on the characteristics of these methods, the moving band is selected as the most appropriate for the simulation of magnetically geared machines. This method is implemented in an in-house finite element package and its performance is evaluated using two case studies. The accuracy as well as the computational efficiency of the moving band technique is compared to that of the air-gap element. For magnetically geared machines, the moving band is the preferred choice because of its low computational cost and acceptable accuracy.

Resolvers are widely used in electric driven systems especially in high precision servomechanisms. Both encapsulated and pancake resolvers suffer from a major drawback: static eccentricity (SE). This drawback causes a significant increase in resolver output position error (RPE) which could not be corrected electronically. To reduce RPE, this paper proposes a novel structure with axial flux.
