초록

A power generation unit is connected with an engine rotary shaft via an accessory gearbox. A rotor extends through the accessory gearbox and a drive gear is disposed at an intermediate portion of the rotor for driving the latter. Permanent magnet elements are mounted on opposite side portions with the intermediate portion intervening therebetween, and stator coils are disposed so as to confront respective outer peripheries of the permanent magnet elements.
