Three-phase Planar Actuator's Reduced Model Validation Using Exploratory Coils and Evaluation Applying Somaloy500 as Core Material

Abstract

This article applies the Three-phase Planar Actuator (T.P.A.) core in two configurations: complete and reduced model for analysis in numerical and real modes. The T.P.A. is a two degree of freedom induction machine similar as two linear motors in a unique traction element. To validate the simulations, a real T.P.A. was built with Steel1010 as core material. The magnetic flux was measured by exploratory coils and compared with numerical model software's results. After the validation, the core's material was substituted by SMC Somaloy500 – which has a high magnetic permeability allied with a higher resistivity than Steel1010 – and new simulations were made with variation of operating frequencies. The validation's results indicate a correct numerical modelled device with a maximum error of 9,64% and a better response with SMC Somaloy500 for force measurements – especially in relative high frequencies up to 120Hz. With Somaloy500 the x-axis force were almost 9 times higher than the Steel1010 as primary core material.
