METHOD FOR STABILISATION OF POWER GYROSTABILISER ROTATION TORQUE Russian patent published in 2010 - IPC H02P23/08 H02P27/04 

FIELD: electric engineering.

SUBSTANCE: circuits of pulse width control of phase voltages in asynchronous motor with short-circuited rotor are used jointly. At the same time, torque of power gyrostabiliser flywheel asynchronous motor is adjusted proportionally to value of control signal, coming, for instance from sensor of orientation or software setting units, in pauses between control pulses asynchronous motor of flywheel is fully disconnected from source of power supply, in established mode asynchronous motor of flywheel functions in zone of low signals, torque at motor shaft is maintained as 10-20% of maximum one, in non-stationary sections of motor speed-up and braking they control voltage at all phases of motor, in order to adjust required torque on shaft of flywheel asynchronous motor, parametre of stator phase currents are formed depending on signals of motor rotor circuit parametres assessment and speed of its rotor rotation, at the same time in process of primary flywheel speed-up till rated speed and stabilisation of rotation speed, on the basis of speed-up and recuperative braking of motor they vary speed within restricted limits versus rated value, that is ±(10÷40)% of rated value.

EFFECT: system simplification combined with reliability improvement.
