2-D equivalent finite element model of quadratic linear electromagnetic actuator

The purpose of this paper is to present a 2-D equivalent finite element model of a quadratic linear electromagnetic actuator that can save space and power as it does not employ an energy conversion system. A 2-D model, while being fairly accurate, is preferable to a 3-D finite element analysis for the design and analysis of a quadratic linear electromagnetic actuator as it requires significantly lower computing resources and results in faster calculations. We calculate the effective coil length for the equivalent 2-D finite element model and validate the accuracy of this model with experimental data. © JVE INTERNATIONAL LTD.
