Beschreibung
Zusammenfassung:	FIELD: electrical engineering;; variable-speed drives using induction drive motors. SUBSTANCE: variable-speed ac drive has parameter setting unit, integral regulator, proportional regulator, differentiating unit, multiplying unit, adders, off-line voltage inverter, induction motor, module separation unit, dividing unit, switch, comparison unit, and speed transducer. Speed control is effected independently of changes in dynamic properties of drive motor. EFFECT: enhanced speed and operating stability in wide speed control range. 1 cl, 1 dwg
