BEM-FEM COUPLING IN ELECTROMECHANICS: A 2-D WATCH STEPPING MOTOR DRIVEN BY A THIN WIRE COIL

Abstract

This paper deals with the transient numerical analysis of 2-d electromechanical devices driven by thin wire coils. Their dynamical behavior is described by the Maxwell equations, by the constitutive relations, and by the equations of motion. For the solution of the electromagnetic problem the BEM-FEM coupling method is used. A two- dimensional watch stepping motor is presented as an example.
