ELECTRICAL MACHINE WITH DOUBLE-PACK INDUCTOR (VERSIONS) Russian patent published in 2009 - IPC H02K19/06 H02K19/20 

FIELD: electricity.

SUBSTANCE: invention is attributed to electric engineering, in particular to low-speed high-torque electromotors, electrical drives and high-frequency electric generators. Suggested electrical machine contains armature with imbricated core, polyphase coil winding located on its pole tips, and cylinder double-pack inductor containing imbricated core with pole tips. The armature is made single-pack, its winding consists of coils each one of which is located on separate tooth. Excitation is performed by ring winding located between two inductor cores the teeth of which are shifted so that each tooth axis of the first armature coincides with each groove axis of the second armature of inductor. Herein, electrical machine consists of modules - elementary machines. Electric connection between rotating winding of electrical machine with double-pack inductor and external electric circuit is performed by means of brushes and contact rings, and number of armature teeth and number of teeth of inductor's any core is determined from expressions containing values that determine phase number of armature winding, number of armature's teeth falling on one module, and number of modules.

EFFECT: achieving high specific torque at low rotation frequencies in motor mode of operation of electrical machine, and high specific power at high frequencies in generator mode.
