摘要: This study describes a design feature for variable-airgap, cylindrical, linear variable reluctance actuators, which enhances their force capability at large airgaps. These features enable the actuators' force-displacement characteristics to be tailored requirements of particular application. The method presented is based on incorporating series circular grooves into stator pole faces and corresponding projections armature. utility these demonstrated by means an actuator with rated 1 kN over stroke 3 mm. findings from are validated experimental measurements.
