ELECTRIC MOTOR DRIVE FOR LAYING OF SHOOT WIRE IN SHUTTLELESS LOOMS Russian patent published in 1995 - IPC

Abstract RU 2035122 C1

FIELD: electrical engineering. SUBSTANCE: characteristic feature of invention lies in that field structure and runner work jointly as linear synchronous motor, reactive, hysteresis or with permanent magnet which provides for lack of heating of runner in process of speed-up. Smooth increase of speed of travelling magnetic wave in field structure and speed of synchronously moving runner are ensured by smooth growth of current frequency by law set by special function generator. EFFECT: enhanced operational reliability of electric motor drive. 4 cl, 1 dwg
