Abstract
A wirelessly actuated motor has wide potential application in in-vivo mechatronic devices, due to the absence of power and control cables from outside the device. This paper presents a magnetically actuated wireless motor with no net force acting on the device. The developed motor has a double crank; each connecting rod accommodates a 5 mm neodymium magnet, actuated using a magnetic field produced by an electromagnetic coil system located nearby. The magnetic field aligned parallel to the direction of the magnet produces a magnetic force. The magnets are oppositely oriented, so experience attraction and repulsion forces, the crank converts this into a rotational motion. By altering the direction of the magnetic field, these forces are switched, and by using a ratchet a rotational motion in a single direction is produced.
