METHOD FOR CONTROLLING INDUCTION MOTOR SPEED Russian patent published in 2003 - IPC

Abstract RU 2199815 C2

FIELD: electrical engineering; induction-motor drives. SUBSTANCE: control voltage is applied to induction motor windings at the same time varying frequency and RMS value of control voltage; control voltage is supplied from AC mains; in the process period of control voltage application is steplessly varied, this period being equal to supply voltage cycle. EFFECT: enlarged control range. 2 dwg
