Abstract: This paper presents the design and analysis of electromagnetic field
distribution and torque characteristics of a novel three degrees of freedom
deflection type permanent magnet actuator based on 3D finite element method and
comparison analysis. The spatial magnetic field model, torque calculation model
and 3D finite element application are presented and developed. Based on the
calculation results, some important structure parameters' effects on the
electromagnetic field and torque characteristics are discussed in detail with
improved design schemes. The results provide the primary theoretical guide for
the configuration design, optimization and control research of three degrees of
freedom deflection type actuators.
