Problems solved by technology

Therefore, if a starter and generator device is used in a vehicle equipped with a four-stroke engine, and an automatic transmission mechanism is arranged at the end of the crankshaft, the crankshaft will become longer.
[0005] On the other hand, in order to suppress the length of the crankshaft, when the above-mentioned governor mechanism, brush mechanism, camshaft drive mechanism, automatic transmission mechanism, etc. are arranged close to each other, it is not possible to secure an angle sensor on the crankshaft for detecting its rotation angle. space

Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings. Fig. 6 is an overall side view of a motorcycle equipped with a starter-generator device according to an embodiment of the present invention. The front part 2 of the vehicle body is connected to the rear part 3 of the vehicle body through the floor part 4 at a lower position, and the frame of the vehicle body is formed by a frame including a down pipe 6 and a main pipe 7 . A fuel tank and a storage tank (both not shown in the figure) are supported by a main pipe 7, and a vehicle seat 8 is arranged above it. The seat 8 can also be used as a lid of a trunk provided under the seat 8, and the trunk can be freely opened and closed by a hinge mechanism provided at the front part FR.

[0017] In the front part 2 of the vehicle body, a steering head 5 is provided on the down tube 6, and the front fork 12 is pivotally supported by the steering head 5. A steering handle 11A is at...

Abstract

The invention provides a starter / generator which can be disposed on an end of a crankshaft without increasing the length of the crankshaft. To achieve this, a starter / generator includes a brushless motor 44 having a rotor 15 connected to an end of a crankshaft 12 and a stator including a starter coil 51 and a generator coil 50, a start control means (a three-phase driver 104, a rotor sensor 56, etc.) for converting a battery voltage into AC power and supplying the AC power to the starter coil 51 of the brushless motor 44, and a generation control means (a regulator 52) for supplying electromotive forces induced across the generator coil 50 of the brushless motor 44 to electric loads.

Description

technical field [0001] The present invention relates to a starter and generator for a vehicle which is integrated with a starter for an internal combustion engine mounted on a vehicle and a generator, in particular to a starter and generator for a vehicle which is directly connected to a crankshaft of an internal combustion engine. Background technique [0002] In the starter and generator device used in the existing internal combustion engine (hereinafter referred to as "engine"), as described in Japanese Patent Application Laid-Open No. 10-148142, a starter coil and a generator coil are arranged on the starter of the motor, and when starting, the The battery supplies power to the starter coil through the brush mechanism, and the motor is used as a starter to turn the crankshaft, which is directly connected to the rotor, to start the engine. [0003] On the other hand, the commutator of the motor and the brush are in contact with the governor mechanism. After the engine is ...
