ABSTRACT:
A motor driven magnetically coupled variable capacitor including a follower magnet arranged internally of the capacitor and fixedly coupled to a rotatable shaft, a follower magnet drive magnetically coupled to the follower magnet for rotating the follower magnet and therefore the rotatalbe shaft, a plurality of stationary capacitive elements fixedly mounted at one end of the capacitor, and a plurality of movable capacitive elements mechanically coupled to the rotatable shaft for axial movement therealong in response to rotation of the rotatable shaft by the follower magnet. The movable capacitive elements coacting with the stationary capacitive elements to vary the capacitance of the capacitor in response to activation of the follower magnet drive.
