FIELD: electricity.
SUBSTANCE: in a drive of slotted guide antenna rotation, a brushless sensor-free synchronous motor is controlled, at the same time the direct drive of slotted guide antenna rotation on the basis of the brushless sensor-free synchronous motor is located on the antenna post body cover and comprises an external rotor with permanent magnets, connected via a flange joint with the slotted guide antenna, and a stator rigidly fixed on the antenna post cover. Three phases of synchronous motor stator winding are arranged in the form of alternating radial poles. Direct drive configuration is simplified, and therefore drive manufacturing cost is reduced.
EFFECT: simplified configuration of a drive, creation of a reliable and cheap device and method to control engine operation, provision of smooth speed-up of antenna rotation as a command is supplied to a drive actuation circuit and smooth stop of an antenna as a drive is disconnected.
