SYNCHRONOUS MOTOR WITH MAGNETIC REDUCTION Russian patent published in 2018 - IPC H02K51/00 H02K21/24 H02K19/06 H02K16/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to electric machines with magnetic reduction. Synchronous motor with magnetic reduction comprises rings of the magnetic conductor stator, a high-rotation rotor with permanent magnets and a low-rotating rotor. Low-rotation stator rotor disks have ferromagnetic and non-magnetic elements in the form of sectors. High-rotation rotor relies on the bearing mounted on the slow-rotation rotor shaft. Quantities of ferromagnetic elements on stator disk z_c and on rotor disk z_p are connected by equality z_p=z_c±2p, wherein p is a number of pairs of poles of stator winding. Plated teeth with coils and crowns installed on the end surface of the second ring of the stator magnetic conductor and having the same angular positions with teeth, coils and crowns on the first ring of the stator magnetic conductor are additionally placed. On the end surfaces of the crowns of the teeth, there are protrusions, the position of which coincides with the ferromagnetic elements of the stator disks. High-rotation rotor is located in the middle of the motor.

EFFECT: improved energy characteristics, increased reliability.
