ABSTRACT

This paper is concerned with properly sizing all parts of a DC Limited Angle Torque Motor aiming to obtain higher electromagnetic torque and higher uniformity degree of the torque-angle characteristic for the operating range. The magnetic field analysis conducted using the finite element method allowed for successive improvements that led to satisfying the design requirements. The usage of numerical models requires less prototyping through experimental models, which result in shorter design cycle and reduced fabrication costs.
