Abstract

The present invention relates to a magnet rotation type alternating current generation method and a generator, in particular, the principle of power generation correctly established, the formula for the number of revolutions and the number of poles, frequency relationship, winding angle and pole angle, phase angle and improve the shape of the pole In order to make a generator that can produce efficiency, the problem of general generator is wrongly explained in the direction and period of induced electromotive force when a magnet or coil rotates once, and the number of stimulus is twice as high as it is related to the angular velocity in frequency. In the stimulus, the stimulus size is larger than the stimulus interval, thereby reducing the power generation efficiency and increasing the power consumption. In brief, if the magnet or coil rotates once, the magnetic flux through the coil increases when rotating from 0 to 90 degrees according to the law of Lenz, and the induced electromotive force is rotated 90 to 180 degrees in the counterclockwise direction. The magnetic flux through the coil decreases and the induced electromotive force rotates negatively (-) 180-270 degrees clockwise. The magnetic flux through the coil increases and the induced electromotive force rotates the positive (+) waveform 270-360 degrees counterclockwise. The magnetic flux is reduced and the induced electromotive force becomes negative (-) waveform in the clockwise direction, so as shown in FIG. In terms of frequency, it is 1f by one rotation (360 degrees) using the frequency method, and 2πf by one rotation (2π) when the arc method is used. In the frequency calculation, the angular velocity is used to correlate with the angular velocity, so that the frequency f = pn / 2 × 60, and in the frequency method, the frequency f = pn / 60, resulting in the stimulus number p = f × 2 × 60 / n. Since the number of stimulus p = f × 60 / n, the rotational speed and the frequency are proportional, so the frequency method should be used. In the case of 16 poles, the pole angle and winding angle are 22.5 degrees, and the phase angle in three phase winding is 7.5. The magnetic pole size should not be larger or smaller than the 1 phase phase angle. Energy efficiency is saved by maximizing the coercive force at both ends of the magnetic pole by excluding the force to be adsorbed with the magnetic pole and the magnetic field, thereby maximizing the coercive force at both ends. In this way, it is beneficial to save more than 50-40% energy when manufacturing a generator.
