Numerical Analysis of Magnetic Compounds used to Make Induction Planar Actuator Core with Two Degrees Of Freedom

Research exposes the electric planar actuator as an element of traction which can be employed for bidirectional movement performed by a single mechanism as an alternative to the usual composed disposition of mechanical components and rotary motors used in industrial applications. Considering the capacity of the surface motors to produce kinetic energy with minimum mechanical contact between the stator and the translator, thus it reduces the friction and consequently eliminates this and other nonlinearities present in other drive technologies normally used. When the process of powder metallurgy is used, it is possible to build unique massive blocks cores with high magnetic permeability and advantages can be obtained when compared to conventional cores, such as motors with lower energy consumption and higher efficiency. Therefore the focus of this paper concentrates on simulations of magnetic compounds and alloys through analysis by the Finite Element Method with support for three-dimensional models applied in the confection of magnetic circuits used in planar actuator. The performance of the cores was analyzed by magnetic field density spectral with numerical information of the maximum magnetic flux density and the influence of the variation of the supply frequency.
