Title:
DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/041200
Kind Code:
A1
Abstract:
A drive device comprises a rotor having a helical projection part, a stator having a helical groove part, and an output part for driving by movement of the rotor, and has a configuration in which the helical rotor and stator are combined together. The rotor is composed of one or more rotor units having a length in the axial direction of the rotor that is less than the length of a circulation track, the rotor unit allows movement of the rotor on the circulation track by the advancement action of the rotor unit in the axial direction during helical movement with respect to the rotor, the helical portions of the rotor and the stator are caused to face each other, and the torque density of the drive torque is increased by using the magnetic force therebetween.
