Modeling and implementation based control of a novel radial-gap helical ROTLIN machine

This paper presents a research on design, modeling, simulation and implementation based control of a novel ROTLIN (Rotary-Linear) Radial Gap Helical Machine. The machine is comprised of Stator, Mid-Layer Rotor and the Inner Layer Translator. Structurally, it is made using smartly piecewise helical-shaped Permanent Magnet (PM) which are radially magnetized and helically layered on both Rotor and Translator. This machine has a wide range of applications, it can be used for linear actuation or for wave energy harvesting. The 3D FEA simulation results and calculations confirmed the realization of rotary and linear motions. This compact machine can realize high Thrust Force densities and high backdrivability when used as a linear actuator.
