Vehicle-use generator
First Claim
1. A vehicle-use generator comprising:
- a rotor rotatably mounted on a shaft and having a field coil wound therearound;
a stator having stator winding wound therearound and fixedly disposed so as to form a gap with the rotor;
a cooling fan mounted to said rotor;
a pulley belt-driven by a vehicle engine and coupled to said shaft through an overrunning clutch provided therein; and
a power generation control device controlling an excitation current flowing into said field coil such that an output voltage of said vehicle-use generator is kept at a target regulation voltage;
wherein said overrunning clutch is configured to idle when a rotational speed of said pulley is lower than a rotational speed of said rotor to inhibit torque transmission from said pulley to said rotor, and said power generation control device is configured to forcibly increase said excitation current on a temporary basis when an upshift operation of a transmission of said vehicle is performed.

Abstract
The vehicle-use generator includes a rotor rotatably mounted on a shaft and having a field coil wound therearound, a stator having stator winding wound therearound and fixedly disposed so as to form a gap with the rotor, a cooling fan mounted to the rotor, a pulley belt-driven by a vehicle engine and coupled to the shaft through an overrunning clutch provided therein, and a power generation control device controlling an excitation current flowing into the field coil. The overrunning clutch is configured to idle when a rotational speed of the pulley is lower than a rotational speed of the rotor to inhibit torque transmission from the pulley to the rotor, and the power generation control device is configured to forcibly increase the excitation current on a temporary basis when an upshift operation of a transmission of the vehicle is performed.
