MOTOR-COMPRESSOR Russian patent published in 1997 - IPC

Abstract RU 2079714 C1

FIELD: manufacture of refrigerating compressors; hermetic motor-compressor domestic refrigerators. SUBSTANCE: toothed stator 5 is provided with main and commutating poles 14 and 15 which are embraced respectively by main windings 8 and 9 and additional windings 16 and 17; teeth of commutating poles are shifted relative to those of main poles so that minimum angle between them is equal to (K + (0.25-0.44)) tz, where tz is tooth pitch and K = 1, 2, 3, ...; toothed rotor 10 has no windings; windings are supplied from electric switch by signals received from sensor showing position of rotor relative to stator. EFFECT: enhanced reliability. 2 dwg
