MAGNETIC REDUCER Russian patent published in 2009 - IPC H02K51/00 F16H1/06 

FIELD: electric engineering.

SUBSTANCE: invention is related to electric engineering, to electromagnet mechanisms, and more specifically, to contactless magnetic reducers, and may be used as transmission device in mechanical systems with high resource of operation under impact loads. Magnetic reducer has rotor of fast rotation with permanent magnets (1), magnetised tangentially, wedge-like pole tips (2) with convex profiled surfaces inverted to working gap, non-magnetic bush (3) for fitting onto shaft of fast rotation (4). Magnetic core (5) with evenly installed teeth inverted to working gap, is fixed to body (6), with which hollow cylinders (7) are mechanically connected by non-magnet ring (10), which have alternating ferromagnetic and non-magnet elements. Rotor of slow rotation represents hollow cylinders (8) mechanically connected to shaft of slow rotation (9) by means of non-magnet disk (11) and has alternating ferromagnetic and non-magnet elements. Due to introduction of hollow cylinders of stator and rotor of slow rotation, magnetic reducer is produced with high transmission torque from alternating ferromagnetic and non-magnetic elements.

EFFECT: improvement of mass and dimensional parameters.
