ELECTRICAL MACHINE Russian patent published in 2002 - IPC

Abstract RU 2187878 C1

FIELD: electrical engineering; singlephase electrical machines for domestic appliances. SUBSTANCE: electrical machine has unwound toothed rotor with double- tooth poles carrying concentrated-winding coils. At least one slot of double-tooth poles accommodates permanent magnet cumulative with magnetizing coil; winding is connected to outputs of electronic switch for being energized depending on angular position of rotor relative to stator. Stator pole number equals k and rotor tooth number is 3k, where k = 4, 6, 8 . EFFECT: enhanced efficiency due to enlarged spaces between energizing moments of stator winding coils. 2 cl, 2 dwg
