摘要:
The paper presents the results of an investigation into the Laws relay type of limited-motion rotary servoactuator. Laws's prediction relations based on magnetic equivalent circuits of the actuator are examined, extended and presented in SI units. Quantitative comparisons between predictions and test results for a large actuator recently designed for an industrial application are discussed. Design aspects are outlined, and the use of the finite-element technique for dealing with highly saturated designs is illustrated.
