<p>PURPOSE: To prevent the occurrence of a voltage drop against an abrupt load by dividing the fixed coil of a rotary transformer into a main coil and auxiliary coil and making a load current to flow to the main coil, and then, applying a load voltage across the auxiliary coil through an automatic voltage regulator. CONSTITUTION: A shaft 1 is fitted with a field pole 2 incorporating a field coil 3, and an armature iron plate 14 and armature coil 15 wound around an armature iron core 14 are fixed to the outer periphery of the pole 2 in a state that the plate 14 and coil 15 are isolated from the pole 2. A load current and load voltage are fed back to the coil 3 and controlled by means of a rotary transformer 4 through a rectifier 5. Therefore, the occurrence of a voltage drop against an abrupt load can be prevented.</p> |
