RADAR ANTENNA ROTATION MOTOR CONTROL SYSTEM AND METHOD Russian patent published in 2015 - IPC H02P27/06 H01Q3/34 

FIELD: electricity.

SUBSTANCE: in a radar antenna rotation motor control method the following parameters are defined: mean power, amplitude variable component for the motor shaft power, power pulsation factor, instantaneous power at the motor shaft, its average speed, amplitude of the speed variable component, speed pulsation factor, which is maintained at a permitted level by an impact to the inverter by a signal proportional to the variable component of the moment resistance at the motor shaft and being in opposite phase with the above signal. In order to implement the above method the radar antenna rotation motor control system includes additionally a moment corrector and calculators of power, power pulsation factor, rotation speed parameters, speed pulsation factor with respective relations.

EFFECT: improved technical and economic characteristics due to the reduced variable of power at the motor shaft and increased reliability.
