Reversing-free DC electric generator and power generation method thereof

Abstract

The invention discloses a power generation method which can generate constant stable DC current and output voltage and current in a reversing-free way, and leads the capacity of a single machine not to be limited; the invention also relates to a novel DC electric generator designed by the method. The method comprises: when a coil is cut, the cutting directions of magnetic force lines are opposite to each other at the two sides of the coil, and the magnetic field direction and the direction along which the coil is cut by the magnetic field are unchangeable. The electric generator comprises two rotors (5) and (6) as well as a magnet yoke (1), wherein the two rotors are magnetic bodies and rotate towards the opposite directions at the same speed; a magnetic pole of each rotor is provided with a plurality of bulges (62) and pits (61), and the magnetic force lines are concentrated at the positions of the bulges, so that the uneven distribution of the magnetic field can be caused. A stator is formed by a plurality of coils provided with independent iron cores, and neutral positions are arranged among the coils, so that the magnetic fields of induced current are respectively independent. The stand magnet yoke is used for reinforcing the magnetic fields. As an armature is the stator, an electric brush and a sliding ring can be omitted, the DC current is induced in the armature and has no inductive reactance, and the novel DC electric generator has higher efficiency than an AC electric generator and a reversing-type DC electric generator.

Description

technical field [0001] The invention relates to a method for directly generating direct current, and also relates to a generator using the method to generate current. Background technique [0002] In the existing unipolar motor, the armature part of the motor is cast steel or forged steel optical axis, which uses the optical axis to cut the magnetic force line in the unipolar magnetic field to generate direct current, and then uses the brush to introduce the current into the external circuit. The armature of this motor has no windings, so the induced electromotive force is limited, the voltage is low, the body is large, and the brushes wear out quickly. Due to the need to use brushes to draw current, the capacity of a single machine is limited. [0003] The commonly used DC motor is essentially an AC motor equipped with a commutator, which uses the commutator to convert alternating current into direct current output. Because the armature is still alternating current, the i...

AI Technical Summary

Problems solved by technology

Because the armature is still alternating current, the impedance is large, the efficiency is low, and the brushes wear out quickly. Because the commutator is used, the electric spark generated will damage the brushes and commutator, and the capacity of the single machine is also limited.

After the alternating current is commutated, the current still pulsates, and it is impossible to obtain a stable direct current
