SYNCHRONOUS RELUCTANCE MACHINE Russian patent published in 2011 - IPC H02K19/10 H02K19/24 H02K29/03 

FIELD: electricity.

SUBSTANCE: in the proposed synchronous reluctance machine, which comprises a multiphase power winding on a stator, which is evenly distributed along an inner bore of the stator and designed for connection to a valve converter, and also a multiphase excitation winding with a full pitch, designed for connection to controlled exciters, according to the invention, at the edges of each rotor pole there is a corrugation arranged in the form of grooves with the pitch h = 8 - 10 mm, and their bases are located in planes parallel to axis of rotor rotation, at the same time the width of each groove is a = 2 - 4 mm, the depth b = 8- 10 mm.

EFFECT: reduced heating of a synchronous reluctance machine rotor due to lower magnetic losses caused by pulsations of excitation magnetomotive force.
