ROTATING ELECTRIC MACHINE EQUIPPED WITH MAGNETIC FLOW CONTROL MECHANISM Russian patent published in 2019 - IPC H02K21/14 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electric engineering, in particular to the rotating electric machine equipped with the magnetic flow control mechanism. Electric machine includes main part of housing, movable mechanism moving at reception of centrifugal force, element of magnetic flux shunting and displacing springs. Cam element includes a cam surface so as to be facing the movable mechanism and to come into contact with the movable mechanism, and the cam member converts the radial movement of the movable gear received by the cam surface into an axial movement of the magnetic flux shunting element. Displacing springs impart magnetic force displacing force to shunting element in direction away from axial end surface of rotor core, so as to determine the position of the magnetic flux shunting element in the axial direction in a state when the biasing force is balanced by the centrifugal force applied to the movable mechanism through the cam member.

EFFECT: invention is intended to change magnetic flux directed from permanent magnet to stator winding without use of special actuator.
