A vertical magnetic transmission assembly includes a shelf, a transmission shaft, multiple magnetic modules and a weight. The shelf has multiple boards disposed along a longitudinal direction of the shelf. The magnetic modules are respectively mounted in multiple through holes formed in the boards. The transmission shaft with the weight rotates along the longitudinal direction of the shelf without friction by magnetic force between the magnetic modules and the magnets of transmission shaft. Therefore, the rotation speed or the torsion of the transmission shaft will be increased in use. An energy-saving generator is further combined with the vertical magnetic transmission assembly to reduce the energy loss in the energy transfer process and to save energy.

A mechanism including a rotary element and a magnetic device for guiding this rotary element in rotation arranged so as to exert a radial magnetic biasing force on the rotary element when a central axis of this rotary element undergoes a radial movement relative to a given axis of rotation. The magnetic device includes a pair of annular magnets the first annular magnet of which is carried by the rotary element and the second annular magnet is carried by a structure of the mechanism. The second annular magnet is parallel and axially superimposed with the first annular magnet when the central axis of the rotary element is coincident with the axis of rotation, the first and second annular magnets being arranged in magnetic attraction so as to impart on one another an axial magnetic force and a radial magnetic force.

A magnetic bearing retains a rotatable shaft in a selected position by magnetic coupling between two circularmagnetic assemblies, one of which is connected to the shaft. Each magnetic coupling completes a magnetic circuit. Shaft rotation does not affect the magnetic circuit, but radial displacement of the shaft disrupts the magnetic circuit and increases magnetic reluctance. Increasing magnetic reluctance inhibits radial displacement. The shaft thereby supports a load while rotating freely, constrained to a selected position by forces of magnetic reluctance. A bearing may be employed to maintain gap distance between the magnetic assemblies.

A pump may include a stator, a rotor, and an impeller. The stator may include one or more electromagnets and one or more permanent magnets. The rotor may include an armature, one or more complementary permanent magnets, and a pull magnet configured to position the rotor in an axial direction. The rotor may be disposed within the stator. The complementary permanent magnets and the one or more permanent magnets of the stator may create magnetic bearings. The armature may be aligned with at least one of the electromagnets of the stator and configured to rotate the rotor with respect to the stator. The impeller may be coupled to the rotor.
