METHOD FOR ACCELERATING HYDRAULIC INDUCTION MOTOR Russian patent published in 2006 - IPC G01C19/08

Abstract SU 1840210 A1

FIELD: electrical engineering; forced frequency acceleration of induction motors.

SUBSTANCE: proposed method involves step-by-step variation of hydraulic motor frequency of rotation until rated speed and stabilized current are attained. In addition, hydraulic-motor active power is measured after each change in frequency of rotation. Upon attainment of maximum motor speed is abruptly augmented.

EFFECT: reduced acceleration time.
