ANCHOR OF MULTI-PHASE ELECTRIC MACHINE Russian patent published in 2019 - IPC H02K1/16 H02K3/28 

FIELD: electrical engineering.

SUBSTANCE: anchor is made of two parts, each of which has length L and is turned around rotor axis of rotation relative to second part at angle of 30/p geometrical degrees, where p is number of pairs of poles. In each of parts of anchor in open slots of armature rotor yoke core packs are arranged. Packs are made in the form of bar. In each sheet with a tooth core in circumferential direction there are q open slots of rectangular shape, where q is even number from natural row, starting from q = 2. Symmetry axes of the grooves are turned relative to each other around the axis of rotation of the cylinder by angle of 360/2qmp of geometrical degrees and are symmetrically placed relative to the internal surface of the tooth core. Packages with tooth cores are turned in plane perpendicular to package rotation axis relative to each other by angle of 360/2mp geometric degrees. In each part of anchor magnetic system there are 2qmp packages of bar-shaped tips with bar shape 2L long. There is a cut in the middle of each sheet of each packet of a tooth-tip.

EFFECT: technical result is reduction of braking electromagnetic moments, reduction of additional losses from longitudinal eddy currents in sheets of electric steel of yoke of stator.
