Abstract
A motive force generating device includes a rotating member, a driving magnet unit, a driven magnet unit, and a sensor unit. The driving magnet unit is disposed at a position relative to the rotating member. The driven magnet unit is mounted on and is co-rotatable with the rotating member. The driving magnet unit is alternately enabled and disabled by the sensor unit so as to cause rotation of the rotating member.
Claims13
A motive force generating device, comprising:
- a rotating member rotatable about an axis of rotation;
- a driving magnet unit disposed at a position relative to said rotating member;
- a driven magnet unit mounted on and co-rotatable with said rotating member;
- and
- a sensor unit for causing one of said driving and driven magnet units to generate a magnetic field when said rotating member is at a first angular orientation relative to said driving magnet unit such that said driving and driven magnet units generate magnetic forces for causing rotation of said rotating member;
- said sensor unit disabling said one of said driving and driven magnet units from generating the magnetic field when said rotating member is at a second angular orientation relative to said driving magnet unit, thereby permitting further rotation of said rotating member to the first angular orientation by virtue of inertia.
