INDUCTION ELECTRICAL MACHINE Russian patent published in 2018 - IPC H02K19/24 H02K9/16 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, to synchronous reactive electric motors and generators used in transmissions of self-propelled machines for various purposes. Induction electrical machine contains bearing shields, a shell with a jacket, inside which there is a stator with poles and phase windings made in the form of lumped coils placed on the teeth of the stator magnetic core in its slots. On the shaft of the windingless rotor, a toothed magnetic circuit is fixed. Additionally, depending on the machine versions, the grooves of the stator magnetic core are made with a smooth transition between the teeth and the back of this magnetic circuit; grooves of the stator magnetic core are made with parallel walls; rotor shoe and shaft are made of magnetically soft steel; shirt consists of segments fastened with a stator magnetic core and with each other; machine contains liquid cooling channels located parallel to its axis between the jacket of the housing and the back of the stator magnetic circuit or in the recesses of the back of this magnetic circuit opposite its teeth.

EFFECT: technical result consists in reducing the volume and mass without reducing the power and torque.
