Electrostatic modeling of cavities inside linear actuators

[摘要] This paper describes the modeling of two-dimensional electric fields inside linear actuators where cavities in the cooling environment are present. A semi-analytical model based on Fourier series is extended for cavities and incorporates the curvature of corners. The model shows good agreement with finite element analysis. The effect of position and sizes of the cavity are investigated as well as the curvature of the corners of the cavity.
