Vehicle engine starting device, has capacitor providing electrical alternating current power to armature coil and another capacitor providing electrical power to magnetic field coil such that driving operation is realized to start engine

摘要

The device has a Lundell alternator (4) with magnetic field and armature coils (5, 7) respectively placed in a rotor and a stator. The alternator provides three-phase alternating current to the armature coil such that an electromotive induction force is generated on the field coil and a capacitor (13) is charged with a voltage higher than a preset voltage. A capacitor (61) provides electrical alternating current power to the armature coil, and the capacitor (13) provides the power to the field coil such that a driving operation is realized to start an engine.
