AI Technical Summary

Problems solved by technology

The load on the engine changes due to the stop of power generation, especially in the low rotation area, making the rotation of the engine unstable
And if the power generation is too large, in the low rotation area, the friction force increases, and the influence on the rotation of the engine is also large.

Embodiment Construction

[0020] An embodiment of the present invention will be described below with reference to the drawings. figure 2 It is a sectional view of the starting device and generator according to an embodiment of the present invention. The starter and generator (hereinafter referred to as "ACG") 1 can be mounted on, for example, the engine of a scooter-type motorcycle. The ACG 1 has a stator 50 wound with three-phase coils (stator coils), and an outer rotor 60 connected to the end of a crankshaft 201 of the engine and rotating on the outer periphery of the stator 50 . The outer rotor 60 has a cup-shaped rotor cover 63 connected to the crankshaft 201 , and a magnet 62 accommodated on the inner peripheral surface of the rotor cover 63 . The magnets 62 are arranged on the rotor base along the circumferential direction.

[0021] The outer rotor 60 is installed so that the inner periphery of the bushing 60a fits on the front end taper of the crankshaft 201 and penetrates through the center ...

Abstract

Output control device for synchro generator is disclosed. A generated energy is increased in a low-rotation region with an engine rotation kept stabilized. An engine rotating speed judging unit (48) detects the rotating speed of a rotor, and, when an engine's rotating speed is in a low-rotation region, a driver (46) subjects a rectifier (4) to delay angle energizing control to intensify a field magnetic flux and increase a generated energy. The driver (46) responses to a change in the polarity of a magnetic pole detected by a rotor angle sensor (29), and reads a delay amount stored in a delay angle amount setting unit (49) to subject a stator winding to delay angle energizing. The output voltage of the generator is so controlled as to converge to a value between voltage control values Vmax and Vmin lower than the regulated voltage of a regulator.

Description

[0001] technical field [0002] The invention relates to an output control device of a synchronous engine, in particular to an output control device of a synchronous engine with increased power generation in a low rotation area. Background technique [0003] A three-phase synchronous generator is used as a vehicle power generation device, and the alternating current generated is rectified by a three-phase full-wave rectifier for charging the battery. In the three-phase synchronous generator disclosed in Japanese Unexamined Patent Publication No. 9-19194, a leading phase current flows in the stator coil, and due to the magnetization effect of the armature reaction caused by the leading phase current, the magnetic flux of the magnetic field increases, thereby enabling Increase output (generated voltage and output current). [0004] A general generator is equipped with a voltage stabilizer that limits the output voltage so that the generated electric energy does not exceed a set...
