PLANETARY MAGNETIC REDUCER Russian patent published in 2019 - IPC H02K16/02 H02K51/00 F16H49/00 

FIELD: electrical engineering.

SUBSTANCE: planetary magnetic reduction gear comprises a stator with symmetry axis O₁, consisting of stator magnetic conductor 1 in form of hollow cylinder and permanent magnets of stator 2 with number of pole pairs p_s, inner rotor arranged concentrically to stator and consisting of inner rotor cylindrical magnetic conductor 3, internal rotor permanent magnets 4 with number of pole pairs p_i. External rotor additionally comprises magnetic conductor 5 in form of hollow cylinder having axis of symmetry O₂ and located eccentrically relative to stator and inner rotor. On external surface of magnetic conductor of external rotor 5 external permanent magnets of external rotor 6 with number of pairs of poles p_oo, and on internal surface of magnetic conductor of external rotor 5 there are internal permanent magnets of external rotor 7 with number of pairs of poles p_io. Internal rotor has one degree of freedom, i.e. can rotate only around its own axis of symmetry O₁. At the same time external rotor has two degrees of freedom and is capable of rotation both around axis of symmetry of stator O₁, and around its own axis of symmetry O₂. Low-speed shaft is rigidly connected to inner rotor at point of axis of symmetry of stator O₁, and high-speed shaft is rigidly attached to outer rotor in projection point on it axis of symmetry of stator O₁.

EFFECT: technical result consists in improvement of specific magnitudes of magnetic reduction gear.
