Abstract (en)
[origin: EP1049194A2] A polar rotor device (1) for a satellite reception assembly (100), apt to drive eastward and westward rotations of a dish antenna (300) of such assembly, comprising: a motor (2); a transmission system (3), interposed between the motor and the dish antenna to transform the output motion of the motor into the eastward and westward rotations of the dish antenna, wherein the rotations comprise descending rotations, during which the dish antenna is rotated downward, and ascending rotations, during which the dish antenna is rotated upward; and elastic means (4), arranged at the transmission system, apt to store elastic energy during the descending rotations, and to return elastic energy during the ascending rotations, so that the rotor device can be fed by a receiver of the satellite reception assembly. <IMAGE>
