Design of a Miniature Short-Stroke Constant-Force Linear Actuator
This paper presents the modelling,design and testing of a short-stroke linear actuator to be embedded in a battery-powered positioning device.The particularity of this small (1 cm3) electromagnetic actuator is that it has to provide a constant force along its nominal stroke (1 mm),required by the specifications.In order to achieve this goal,an analytical and two Finite-Element-Method-based models have been developed.A genetic algorithm that takes the force profile into account is used to maximise the nominal thrust force of the actuator.The prototype shows a force profile that has less than 4% of deviation over the stroke and a nominal thrust force of 1.35 N.
