SYSTEM OF AC ELECTRONIC MOTOR CONTROL FOR RADAR ANTENNA ROTATION Russian patent published in 2012 - IPC H01Q7/00 

FIELD: electricity.

SUBSTANCE: control circuit for AC electronic motor of radar antenna rotation includes power correction device, the third current sensor, the second voltage sensor, speed sensor and respective communication liners between components that allow grading of power consumed by antenna electric drive and transmitter power. Power consistency is reached due change in repetition rate of pulses (monitoring pulses) generated by transmitter. It allows elimination of overloading for limited power generator and provision of its stable operation (form point of electromagnetic compatibility the most optimal alternative is when transmitter power decreases at increase of torque at shaft of electric motor for antenna post and vice versa) thus positively affecting the whole operation of radar station.

EFFECT: enhancement of functional capabilities for control of AC electric drive for antenna rotation due to grading power consumed from generator, improvement of tactical and technical efficiency of radar stations.
