Abstract
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.
Claims9
A direct cranking electric rotary machine for a vehicle comprising:
- a rotor fixed to a crankshaft of an engine mounted on the vehicle and serving as a flywheel, and magnet protrusion poles being formed on a first surface of the rotor;
- and
- a stator of an axial air-gap structure placed at an end part of not more than a half circumference on the first surface of the rotor through an air gap, so that a surface of the stator faces the first surface of the rotor through the air gap.
