ELECTRICAL MACHINE Russian patent published in 2008 - IPC H02K19/00 H02K19/10 H02K26/00 

FIELD: electricity.

SUBSTANCE: invention is attributed to the field of electric engineering, specifically - to electric machines and can be used as low-speed high-torque engines, low-speed generators, etc. The essence of invention consists in the fact that in electric machine containing anchor with multiphase coil winding each coil of which is located on separate tooth, coils in phase group are opposite-connected with each other, number of coils in each anchor coil group λ = 2, 3, 4, 5, 6, 7... is integer positive number greater-than-or-equal-to 2, and poles of inductor with exiting winding are made with alternating polarity. At that according to this invention anchor winding coils are grouped in such a way that number of anchor teeth, number of coils in anchor winding coil group, number of coil groups in anchor winding phase and number of inductor poles are connected by certain relations.

EFFECT: efficiency increase and improvement of vibroacoustic performance with simultaneous electric machine cheapening and enhancement of its reliability due to rejection of permanent magnets.
