In this paper, a miniature tubular linear actuator capable of moving and reaching discrete positions inside a tube is presented. Its small size and ability to realize small strokes makes it suitable for biomedical applications. We then present the electromagnetic modeling of the actuator followed by an experimental validation. Results show that the actuator can reach discrete positions inside the tube with an average value of 3.5 mm and a standard deviation of 0.1 mm for a supplied current of 0.5 A.
