ABSTRACT:
A magnetically driven motor includes an output shaft, a magnetic conical plate, a stationary guide, and at least three electromagnets. The output shaft is supported to be rotatable about a predetermined central line. The magnetic conical plate has a vertex on the predetermined central line, is rotatable together with the output shaft about the predetermined central line, is swingably supported to be inclined with respect to the predetermined central line, and has a predetermined peripheral length. The stationary guide has the predetermined central line as an axis, has a vertex angle slightly smaller than a vertex angle of the conical plate, has an annular guide surface corresponding to part of a conical surface of the conical plate, and is adapted such that a peripheral portion of the conical plate is swingable along the guide surface. The guide surface of the stationary guide has a peripheral length larger than that of the conical plate. The electromagnets are equiangularly disposed about the predetermined central line so as to oppose the conical plate and adapted to be sequentially energized. The peripheral portion of the conical plate is swung along the guide surface by a magnetic attraction force acting on the conical plate upon sequential energization of the electromagnets.
