• For magnetic actuators and sensors, mechanical parameters usually influence performance more than any other nonelectromagnetic parameters. For example, armature mass directly affects the speed of response of a magnetic actuator. This chapter uses electromechanical finite elements to analyze the behavior of magnetic actuators and sensors. An electromagnetic finite-element formulation that is capable of analyzing all types of electromagnetic fields is described in the chapter. To allow nonrigid body motion, that is, deformations and stresses, structural finite elements can be used. Structural finite-element analysis is very commonly used to compute mechanical stresses and other mechanical parameters. The chapter shows examples where the motion is small enough such that no element reconnection is required. All results are obtained by time stepping using both nonlinear electromagnetic and structural-finite elements.
