IMPROVEMENTS RELATING TO ELECTRICAL POSITIONAL CONTROL APPARATUS
A description is given of an electrical positional control apparatus having large torque and therefore suitable for controlling hoists for raising and lowering reactor control rcds. The apparaius is of the type comprising a transmitter electrically connected to a motor whose positioning will then depend on the transmitter rotor positioning. The a-c generator has a stator of a plurality of phase windings and a rotor supplied with single-phase a-c voltage, and the motor has a stator with a number of phase windings equal to that of the generator stator windings and a permanent magnet or a d-c excited rotor. The output of the generator stator is rectified and passed through a reversing switch to the motor to cause it to rotate in step with the rotation of the generator. (D.L.C.)
