Summary:
Abstract – This paper presents a novel nano-positioning actuator that has a motion resolution of ±10 nm (limited by encoder resolution) throughout a range of 3 mm. A new dual-magnet configuration is introduced to facilitate this electromagnetically driven actuator to achieve 60 N/A in a compact configuration. The analytical model of the actuator, i.e., the current- force-displacement model has been formulated and then verified experimentally.
In this paper, a new magnetic configuration, which allows this newly proposed actuator to meet those requirements, is presented. Others being presented include: a) a new mathematical model that accurately predicts the behaviour of the new magnetic configuration, and b) a complete analytical model of the flexural support mechanism. Lastly, a prototype is developed and experiments are conducted to validate the proposed mathematical and analytical models, and verify its claimed capabilities.
