Description

DC generator without replenishment, brush and commutator

The present invention relates to a generator, in particular to a DC generator without a supplement, a brush and a commutator, which is not interfered by the magnetic pole generated by the stator when the rotor rotates.

The generator is a device for converting power (such as wind power and hydraulic power) into electric energy by using the principle of electromagnetic induction. Referring to FIG. 6 , the generator 20 mainly includes a rotor module 21 and a certain sub-module 22 . A coil 23 is disposed on the stator module 22, and the rotor module 21 can generate magnetic poles N1 and S1 through an electromagnet or a permanent magnet. When the rotor module 21 is driven to rotate, the coil 23 in the stator module 22 is driven. The magnetic flux changes to cause the coil of the stator module 22 to generate an induced current i3 to achieve power generation.

When the rotor module 21 rotates and approaches the coil 23, the coil 23 generates corresponding magnetic poles N2 and S2, and the magnetic pole N2 generated by the coil 23 is magnetically identical to the magnetic pole N1 of the rotor module 21, so that the rotor When the magnetic pole N1 of the module 21 is close to the magnetic pole N2 generated by the coil 23, the magnetic magnetic force N2 generates a repulsive force, which consumes the kinetic energy of the rotor module 21 and reduces the power generation efficiency, which is a disadvantage of the current generator.

In view of the deficiencies of the prior art generators, the present invention provides a DC generator without an interpole, a brush, and a commutator. The ring coil does not generate a magnetic pole, and the rotor is avoided. A repulsive force is generated between the modules to reduce the influence of the magnetic pole generated by the stator on the magnetic pole of the rotor, so that the rotor can rotate at a constant speed and stably to continuously provide a stable current.

In order to achieve the above objectives, the technical means adopted by the present invention are that the interpole, brush, and commutator DC generators include:

a rotor module, the rotor module includes a rotating shaft and at least one rotating portion, the at least one rotating portion is sleeved on the rotating shaft;

It can be known from the above structure that the DC generator of the present invention, which has an interpole, a brush, and a commutator, transmits the magnetic field required by the generator through the exciting coil, and is formed by the rotating portion. The closed magnetic field line changes when the rotating portion rotates, so that the magnetic flux in the induction coil changes to generate an induced current.

The technical means adopted by the present invention to achieve the foregoing objects will be further clarified below with reference to the drawings and preferred embodiments of the present invention.

The advantage of the toroidal coil is shown in FIG. 1. A toroidal coil 30 in an ideal state includes an annular core 31, a closed coil 32 and a magnet 33. When the closed coil 32 is closed, When a current flows therethrough, a closed magnetic field line Φ is generated. Since the magnetic resistance of the annular core 31 is much smaller than that of the air, the closed magnetic field line Φ passes only through the annular core 31, and the magnet 33 is rotated. The magnetic field line Φ does not generate a magnetic pole, and therefore does not generate a reverse magnetic repulsive force to the magnet 33, and is an ideal model for a non-magnetic pole repulsive force.

Since the induced magnetic force (not shown) does not cause a repulsive force in the loop coil, the kinetic energy of the rotating portion 112 is not consumed, and the rotating portion 112 can be stably rotated at a constant speed without being affected by the induction coil.
