ABSTRACT:
A three-phase variable inductor is disclosed in which a fixed frame is formed by a plurality of laminar plates, the plates being rotated with respect to each other about a common axis. Within the frame, a Y network is located, the Y network being so constructed that the magnetic fields generated thereby during operation cancel out in the radial direction to prevent any net radial force from being exerted against a laminar movable reluctor that can be moved into and out of the frame and Y network. As a result of this construction, vibration is eliminated. Both the frame and the movable reluctor are made of iron and silicon, which reduced heat generation and increases efficiency.
