| Popis: | The future trend of mechanical systems is to substitute most of them by permanent magnet (PM) and/or electromagnetic based ones. This current research highlights a paradigm for future studies of the advanced direct-drivable safe and precise motion actuators, and headlines design, modeling, simulation, and implementation-based control of a novel RotLin (rotary–linear) radial gap helical machine. The machine is comprised of stator, midlayer rotor, and the inner layer translator. This is a hybrid of magnetic screw with a synchronous motor by modifying the design concept. Structurally, it is made using smartly piecewise helical-shaped PM that 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 three-dimensional finite element analysis simulation results and calculations confirmed the realization of rotary and linear motions. To confirm this model, a prototype was enacted and experimental verifications of its performance in terms of direct-drive position and speed control were conducted. This compact machine can realize high thrust-force densities when used as a linear actuator. |
