成果简介	NOVELTY - The three-phase electric machine has a rotor with 2p poles and a stator (1). The stator core comprises Z slots in which a toothed combined winding (3) is placed, and includes two connected toothed windings in which one of toothed windings is assembled in a star pattern and other of the toothed windings is in a triangle. The toothed combined winding is made three-phase symmetrical, so that each of the windings connected in a star and a triangle contains Z/2 coils. The number of slots per pole Z/2p is 6/7, and the number of pairs of poles p is a multiple of seven. USE - Three-phase electric machine used in multi-pole electric motors, motor wheels, propeller drives, electric winches, and electric generators. ADVANTAGE - The efficiency of a three-phase electric machine is increased due to the use of a toothed combined star-delta winding. The field shape of 12-zone windings is closer to sinusoidal than that of 6-zone windings, which reduces additional losses from higher spatial harmonics of the magnetic field and electromagnetic noise. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of an inverted three-phase electric machine with a toothed combined winding. 1Stator 2Stator teeth 3Toothed combined winding 4Rotor 5Rotor winding
