Abstract

PURPOSE:To cut down the cost of construction and the cost of maintenance as well as to suppress the limitation from the viewpoint of conditions of location by a method wherein a movable magnetic field, to be added to an armature coil, is generated in a stationary state instead of the rotation of a prime mover. CONSTITUTION:An armature coil 1 is housed in an iron core 2, the coil end part 1a which is stretched out from the iron core is connected to the armature coil which is positioned leaving a prescribed space, and the coil end part 1a is led out for the purpose of constituting the wire-connection planned in advance. A field coil 3, which makes a pair with the armature coil, is arranged above the iron core. A current can be applied to the coil successively for the purpose of forming a moving magnetic field just like the rotating magnetic field of a rotary electric machine. Also, by switching in the direction of a current, a DC current is supplied from power source facilities having the mechanism in which either of the N-pole and S-pole can be constituted. As a result, the prime mover in power generating equipment and the supplementary facilities, with which the prime mover is operated, are made smaller in size, the cost of construction and the cost of maintenance is cut down, and also the title generator is hardly subjected to the limitation from the standpoint of the conditions of location.
