EXTRA-LOW SPEED ELECTRICAL MACHINE Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: in extra-low speed electrical machine with separated phases, each including several sections furnished with common windings for each section, axis of windings in coaxial with axis of rotation of machine rotor and magnetic circuits with salient poles embrace windings. In each of above indicated sections distance between neighbouring like poles along arc of circumference of stator inner surface or rotor outer surface is equal to where D - diameter of circumference, P - number of pole pairs, τ - designed distance along arc between neighbouring unlike poles of stator or rotor. Z>1, and number of sections in each phase is equal to or is divisible by Z. EFFECT: enlarged operating capabilities. 3 cl, 6 dwg
