ROLLING ROTOR ELECTROMAGNETIC TRANSMISSION Russian patent published in 2022 - IPC H02K41/06 H02K49/10 F16H49/00 

FIELD: electromechanics.

SUBSTANCE: invention relates to the field of electromechanics. The electromagnetic transmission consists of a stator with a main axis O₁ with a winding with a number of pole pairs p_s, an inner rotor concentric to the stator, and an outer rotor located eccentrically relative to the main axis between the stator and the inner rotor. Permanent magnets with the number of pairs of poles p_i are installed on the inner rotor. On the outer surface of the outer rotor permanent magnets are fixed with the number of pole pairs poo, and on the inner surface - with the number of pole pairs poi. The low-speed shaft is rigidly attached to the inner rotor, while the high-speed shaft is attached to the outer one. The outer rotor rotates around the main axis O₁ and around its own axis of symmetry O₂. The distance between the axes O₁O₂ is chosen by the expression O₁O₂=r_si - r_oo - ag_min.o,, where r_si is the inner radius of the stator, r_oo is the outer radius of the outer rotor, ag_min.o is the minimum value of the air gap between the stator and the outer rotor. The outer radius of the inner rotor satisfies the expression r_io=r_oi - O₁O₂ - ag_min.i,, where r_oi is the inner radius of the outer rotor, ag_min.i is the minimum value of the air gap between the outer rotor and the inner rotor, the number of pairs of stator poles, the inner and outer rotors are selected from conditions where n and k are any non-negative integers.

EFFECT: improvement in performance.
