Design of a Linear Electromagnetic Actuator Based on Finite Element Modeling

摘要

Electromagnetic actuators are employed in many applications. It is desired to have a fast and accurate process of development of the actuators. As Finite Element Modeling (FEM) deals well with nonlinearities, present in magnetic systems, a fast and good approach can be achieved making use of this technique. This paper presents the steps of the design of a linear tubular electromagnetic actuator to be employed on an elevator active suspension system. Measurements were carried out on site to assess required specification of the device. Based on these measurements, a linear electromagnetic actuator was proposed, modeled, and results were evaluated.
