SYNCHRONOUS RELUCTANCE MACHINE WITH LIQUID-COOLED STATOR Russian patent published in 2009 - IPC H02K9/19 H02K9/197 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and electric machine production, and pertains to separating electric machine, primarily, self-controlled inverter-bed or synchronous, into subchambers, i.e. stator chamber with liquid cooling and rotor chamber. Proposed synchronous reluctance electric machine with liquid-cooled stator comprises cartridge separating inner chamber of the machine into two concentric stator and rotor subchambers. Aforesaid cartridge features thin-wall cylindrical shell shape, the shell being made from non-conductive non-magnetic material and featuring stepped shape geometrically made up of three main and two jointing coaxial cylindrical unequal-diametre sections, i.e. central and two end sections with jointing sections adjoining their end faces.

EFFECT: ease of manufacture, ruling out electromagnetic losses, reduced weight.
