Direct cranking electric rotary machine for vehicle

摘要

In a direct cranking electric rotary machine as an axial air-gap motor having an improved configuration mounted on a vehicle, a stator is faced to an end part on a surface of a rotor. The rotor also acts as a flywheel for an engine mounted on the vehicle. The length of a circumference of the stator is limited below 180 deg. of its entire circumference. This configuration enables a repair man to easily detach and repair components forming the direct cranking electric rotary machine.
