Abstract :
This paper deals with the transient numerical analysis of electromechanical devices driven by thin wire coils. The dynamic behaviour is described by the Maxwell equations, by the constitutive equations, and by the equations of motion. For the solution of the electromagnetic problem the BEM-FEM coupling method is used. A watch stepping motor is presented as an example
