Abstract
A multiple-reflector antenna for telecommunications satellites including a shaft, to which are attached at least two sub-reflectors, rotating in relation to a load-bearing structure, and a motor including a rotor able to drive the shaft in rotation, and a stator attached to the load-bearing structure, wherein the multiple-reflector antenna also includes two bearings enabling the shaft to rotate in relation to the load-bearing structure, a torsionally rigid mechanical filter placed between the shaft and the rotor, enabling the rotor to transmit the rotational movement to the shaft, and able to dampen the stresses generated by the shaft on the motor, and locking means able to hold the angular position of the shaft in relation to the load-bearing structure.
