Power magnetic planetary gear set

摘要

A power magnetic planetary gear set uses stator of a motor to provide electrically generated magnetic sections. The electrically generated magnetic sections are variable under the excitation control of coils and driver so that either the outer stator or the sun stator of the magnetic planetary gear set may be stationary and still provide self-revolutionary magnetic forces toward the planet gears disposed therebetween. The planet gears are also mounted on planet arms so as to revolve on their own axes and have orbital revolution with respect to the sun stator.

主权项

1. A magnetic planetary gear set, comprising:
an annulus gear; a sun gear disposed at an inner center of the annulus gear and configured to revolve on its own axis, wherein at least one of the annulus gear and the sun gear is stationary and comprises a plurality of teeth circularly arranged by the axis of the sun gear, wherein each of the teeth comprises a pole head, one or a plurality of neighboring pole heads is intertwined with and excited by at least a group of coils to form a variable magnetic section, the plurality of pole heads forms a plurality of similar variable magnetic sections in interlaced polarities, and the polarity of each pole head is changed under the coil excitation control of a driver; and a plurality of planet gears disposed between the annulus gear and the sun gear, each planet gear comprising an axle and a plurality of magnetic elements circularly arranged along the surface of the axle; wherein the plurality of planet gears is mounted on planet arms.
