INDUCTOR MACHINE Russian patent published in 2014 - IPC H02K19/06 H02K19/20 H02K19/24 H02K21/12 H02K1/12 

FIELD: electricity.

SUBSTANCE: inductor machine includes stator installed in magnetically soft housing (1) and made in the form of two laminated packs (2) and (3) from magnetically soft material with teeth (4) on their inner surface, working winding (5), the turns of which are located in slots between teeth (4) restricted as to height with backs (6) of those packs, two rotor packs (7) and (8), which are installed inside bores of stator packs (2) and (3), and excitation winding (9) installed between rotor packs (7) and (8). According to the invention, on outer surface of each stator pack (2) and (3) a provision is made for external teeth (10) oriented along the machine axis, the number of which is equal to the number of stator teeth on its inner surface, external teeth (10) are located above sections of backs (6) of each stator pack, sections of backs (6) under external teeth (10) are located between internal teeth of stator packs (2) and (3), and on inner side of housing (1) there are slots for arrangement of external teeth (10) of stator packs (2) and (3).

EFFECT: reduction of losses in housings of inductor machines and improvement of their efficiency, and reduction of time for transient processes.
