AC Generator Field Stimulus Size and Stimulus Appearance

摘要

The present invention focuses on the magnitude and shape of the field stimulus of an ac generator, particularly focusing on the magnitude and shape of the field stimulus to the Fleming's right-hand rule to improve the quality of current and energy efficiency. Generally, the field stimulus weight and the stimulus (d) area are the central part of the stimulus, so that the armature coil and magnetic induction do not occur, but rather the force to attract the armature iron core The power generation efficiency is lowered. The magnetic induction by Fleming's right-hand rule generates induction electromotive force only at the stimulation interval b 'of FIG. 7, as if the magnetic induction occurs throughout the stimulus, as shown in Fig. 8, It is wrong to express it as S pole.;The field magnet pole 2 of the present invention uses a waste write permanent magnet and an electromagnet and the field magnet pole 2 is concave as shown in the hatched portion 8 of FIG. (2) Let the magnetic force line concentrate on the protrusions of both ends (a) and (b) so that the lines of magnetic force are formed as shown in Fig. 3. The size of the field stimulus (2) is 2: 1 in the size of the second degree and the size of the stimulation interval (b) in the second degree in the 3 phase generator. 1 size. At this time, the one-phase armature coil is wound at the same interval as the stimulation interval (b).;The operation and effect of the present invention will be described as follows.;A field magnet 2 wound around an armature coil 4 on an armature core 5 fixed to the main body 1 and fixed to a shaft 3 is assembled to the main body 1, When the field magnet 2 rotates in the clockwise direction, an induced electromotive force is generated in the armature coil 4 where magnetic lines of force intersect with each other. The electromotive force induced in this manner is determined by the Fleming's right-hand rule in the (a) and (c) position coils 4 where the magnetic poles of the first and second poles (2) (+) Waveform NS occurs as shown in FIG. 1, and a minus (-) waveform ((-)) waveform is generated in the S coil and N pole SN) occurs.;The field magnet pole 2 of the present invention has the center portion of the field magnet pole 2 at a distance from the armature core 5 by a distance corresponding to the area of the field magnet pole hatch 8 as in the detail of FIG. It is possible to exclude the attraction force with the iron core 5 so that the power generation energy can be saved by the attraction force and the field stimulation weight can be reduced by one part of the field magnetization 2 hatching 8 of FIG. It can reduce power generation energy by weight. In addition, more current can be obtained by strong magnetic force because it can concentrate the magnetic force of hatching (8) on both ends (A) and (B) of stimulation. In the case of the three-phase alternator according to the present invention, the size of the pole (a) of the second degree and the pitch of the pole (b) are 2: 1, Since the stimulation interval b is 1: 1 and the winding angle of the armature coil 4 is equal to the stimulation interval b, a high-quality current having no phase difference can be obtained.;By changing the size and shape of the field stimulus, it is very beneficial to increase the power generation efficiency under the same conditions and to save a lot of energy for power generation.
