PROCESS OF OVEREXCITATION OF MULTIMOTOR HYSTERESIS ELECTRIC DRIVE Russian patent published in 1997 - IPC

FIELD: electrical engineering, overexcitation of great number of hysteresis motors connected in parallel. SUBSTANCE: according to proposed process overexcitation pulse is sent into one of phases of each group of multimotor hysteresis electric drive. In each following group it is fed into phase shifted by 2/3P relative to phase of preceding group. For each following group overexcitation pulse is fed with delay equal to 2/3 of period of supply voltage and additional delay of supply of overexcitation pulse by value multiple of period of supply voltage is realized for groups of motors starting from fourth one. EFFECT: enhanced functional stability and reliability of process. 3 dwg
