ASSEMBLED MAGNETIC CORE OF ELECTRICAL MACHINE ARMATURE Russian patent published in 2008 - IPC H02K1/06 H02K19/00 H02K15/02 

FIELD: electrical engineering, applicable in designing of armature magnetic cores of electric machines.

SUBSTANCE: the assembled magnetic core of the electrical machine armature has a section formed by plates of soft magnetic material, in which the lines of the main magnetic flux are oriented to the axis of rotation of the electrical machine mainly at an angle from 70 to 110 deg., according the invention, the section mentioned above has an additional set of plates, each located at angle α within -30 to +30 deg. relative to the machine axis of rotation, and is made bent so that its section located near the mentioned axis of rotation lies mainly tangentially relative to it.

EFFECT: enhanced power of the electrical characteristics due to improved use of the space of the phase sector of the electrical machine armature.
