DEVICE FOR FORCED ACCELERATION OF INDUCTION GYROMOTOR Russian patent published in 2006 - IPC H02P7/42 H02P1/30 G01C19/00

Abstract SU 1840121 A2

FIELD: electrical engineering.

SUBSTANCE: novelty is that proposed device designed to control speed of induction motors used, for instance, in mobile equipment to drive gyroscope flywheels is provided with newly introduced supply mains frequency divider whose input is connected to master crystal oscillator output and output, to phase-sensing acoustic circuit control unit.

EFFECT: ability of varying motor speed in compliance with supply mains frequency.
