ABSTRACT:
Apparatus is provided for simultaneously rotating a plurality of parallel shafts connected, for example, to an array of rf switches that feed energy to or from an array of antenna feed horns. Each shaft is connected by a separate crank to a planar drive plate that is controllable moved relative to the switches in an orbiting fashion, to rotate the shafts in unison. The drive plate is controllably moved by a motor drive system that includes an orbiting motor secured to the plate and a base motor secured to a fixed substrate that houses the switches. The output shafts of the two motors are coupled together such that operation of either motor moves the orbiting motor, and thus the drive plate, in an orbiting motion about the base motor and substrate.
