FIELD: machine building.
SUBSTANCE: invention relates to electric machines and can be used, in particular, in wind-driven power plants and light vehicles. In the proposed electric machine, the stator magnetic core is made in the form of a flat laminated ring with ring coils of the m-phase concentrated winding installed at the end part, and permanent magnets with alternating polarity are arranged on two disk rotors. On periphery of outer sheets of magnetic conductor there are grooves for laying m-phase concentrated winding, at that inner sheets of magnetic conductor are made with diameter smaller than diameter of outer sheets, with formation of annular groove, in which inter-coil connections of winding are arranged. This provides reduced value of air gap of electric machine, which is determined only active conductors of winding, which as a result improves weight and size parameters of machine. Concentrated winding is made with number of slots per pole and phase equal to q = 3/8; 2/5; 3/7; 5/14, or with number of slots equal to Z = 12 + 6k, where k = 1, 2, 3, …, and number of poles equal to 2p = Z ± 2, which provides high winding coefficient values.
EFFECT: technical result is reduction of air gap size.
