CONTROLLED ASYNCHRONOUS MACHINE Russian patent published in 2014 - IPC H02K17/34 H02K51/00 H02P9/02 

FIELD: electricity.

SUBSTANCE: in electrical machine the second armature winding is made combined and located in stator slots of the main magnet core; it is equipped with capacitor bank. Second inductor winding is also combines, multi-phase, short-circuited; it is located in stator slots of the main magnet core. The first winding of rotor is connected to toroidal windings of auxiliary magnet core of the rotor; the first winding of stator is connected to output of frequency converter which converts electric energy of current frequency of the second armature winding to required value of control frequency and delivers it to stator winding of the main magnet core in order to create excitation current and rotating electromagnetic field with this control frequency. Control frequency is set at the output so that frequency of output current is permanent notwithstanding frequency of drive rotation.

EFFECT: reducing weight and overall dimensions and improving cooling and ventilation systems.
