Salient pole rotating field type AC generator

摘要

PURPOSE: To provide a salient-pole revolving-field type ac generator wherein distortions in output voltage waveform due to armature reaction are reduced. ;CONSTITUTION: A pair of poles M1, composed of symmetrically positioned salient poles 1a1, 1b1 and a pair of poles M2, composed of symmetrically positioned salient poles 1a2, 1b2, are placed at intervals of 90° to form a rotor core 1A. Coils Fa1, Fb1, wound around the salient poles 1a1, 1b1, respectively, are connected in series to form a unit field coil F1 (Fa1, Fb1). Coils Fa2, Fb2, wound around the saliett poles 1a2, 1b2, respectively, are connected in series to form a unit field coil F2 (Fa2, Fb2). Diodes D1 and D2 are connected in parallel to apply the output voltage of an exciting dc power supply across the unit field coil F1 (Fa1, Fb1) and across the unit field coil F2 (Fa2, Fb2) in the reverse direction.;COPYRIGHT: (C)1996,JPO
