摘要： An engine-driven generator having a battery powered starter motor includes a permanent magnet battery charger/pre-exciter for charging the starting battery and for exciting the main alternator field winding of an AC synchronous alternator included in the engine-driven generator. A first winding in the permanent magnet battery charger/pre-exciter provides power to a first voltage regulator that, in turn, maintains a desired load voltage substantially independently of alternator loading. A second winding within the permanent magnet battery charger/pre-exciter supplies power to a second voltage regulator that maintains a desired battery charging voltage substantially independently of the alternator loading. Use of the permanent magnet battery charger/pre-exciter maintains a desired battery charge current and a desired main alternator field excitation substantially independently of the load current supplied by the alternator.

摘要： A permanent magnet alternator includes a stator core having outwardly projecting teeth and further includes a plurality of permanent magnets surrounding the stator core. The stator core is formed from a continuous, helically wound metallic strip having a plurality of teeth defined between slots formed in one edge thereof. The stator core is formed by winding the strip edgewise around a cylindrical mandrel. To facilitate winding and avoid distortion, arcuate regions, conforming to the curve of the mandrel, are formed in the strip opposite the teeth.

摘要： An engine-driven generator includes an internal combustion engine, a permanent magnet alternator and an AC to AC converter. The output frequency and voltage of the permanent magnet alternator are largely dependent on engine speed and the alternator load. The AC to AC converter converts the speed-dependent alternating current developed by the alternator to another alternating current whose frequency and voltage are largely independent of engine speed. Voltage regulation is provided by varying the engine speed in accordance with the load current. Frequency regulation is provided by frequency dividing the alternator output by an integer divisor that varies in accordance with engine speed. Additional voltage regulation is provided by deleting selected cycles of the alternator output current as needed to maintain the RMS output voltage within predetermined limits.
