Eddy current loss modelling for torque‐motors [PDF]

open access: yesIET Power Electronics, 2021
Abstract A torque motor is a key component that directly influences the dynamic performance of two‐dimensional (2D) cartridge servo valves. Considering the effects of eddy current, a magnetic circuit model of a torque motor is proposed, and the eddy current resistance value considering the skin effect is calculated.
