MULTIPHASE MOTOR-GENERATOR WITH MAGNETIC ROTOR Russian patent published in 2017 - IPC H02K39/00 H02K99/00 

FIELD: physics, instrumentation.

SUBSTANCE: invention refers to electrical engineering and can be used in power and instrumentation. The permanent magnetic rotor has the form of a parallelepiped, magnetized in parallel to the rotation axis with poles, made with a small gap relative to the stator segment from a thick-walled iron tube with covers with bearings for the rotor axis at its ends. The stator includes K equidistant inner sections, located along its axis, each of which comprises N pairs of stator coils made of spool conductor, magnetically connected with the stator tube. The symmetry axes of spools are at the distance H from each other, which is equal to the thickness of the rotor magnet on its magnetic poles. N pairs of identical stator coils are distributed equidistantly on the inner diameter of the stator tube. Their greatest number HMAX = 2p (R D) / H, where R - is the rotor radius (half-width of the magnet), D - is the gap between the rotor magnet poles and the magnetically conductive spools of the stator coils, the same coil in each pair of stator coils are connected to each other according to the rule: the beginning of one coil in a pair is connected to the other end of the other coil and vice versa, all beginnings of the first stator coils of KH pairs are led out as phase electrodes and their ends are connected to the stator casing, forming a zero electrode, moreover, reduction of the magnetic gap D between rotor and stator is provided by corresponding rounding of magnetic poles with radius R along their thickness H, and the number K of stator sections is determined by length L of the rotor magnet and width S of each of the identical stator sections, i.e. K = L/S.

EFFECT: invention improves efficiency.
