Problems solved by technology

Generally speaking, the magnetic element can be a permanent magnet or an electromagnet. The difference is that the magnetic field of the electromagnet can be controlled by an external current, but the relative structure is more complicated, and the advantage of the permanent magnet is that the structure is simpler, eliminating the need for an electromagnetic Excitation windings, carbon brushes, slip rings and other structures of iron generators, but the size of the magnetic field cannot be changed by current control

Embodiment Construction

[0070] Before describing the following four embodiments, for ease of comparison, only the number of magnetic elements and the rotor speed change as the diameter of the rotor increases, that is, in the generator electric power frequency formula f=pn / 120, the electric power frequency f remains fixed at 50Hz, and the magnetic The number of components p and the rotor speed n change correspondingly; while others such as armature winding size dimension, number of turns and winding method, air gap size, magnetic component size dimension, number of wire slots, armature winding magnetic flux and wire slots on the stator body Conditions such as the number of corresponding rotor magnetic elements remain unchanged. That is to say, in the generator induced voltage formula E=4.44KNΦf, the winding factor K, the number of turns of the armature winding N, the magnetic flux Φ and the power frequency f remain unchanged. In the following four embodiments of the present invention, the electric pow...

Description

technical field [0001] The invention relates to a power generation device, in particular to a power generation device capable of improving power generation efficiency. Background technique [0002] The existing generator is a device that converts kinetic energy or other forms of power into electrical energy. Its working principle is that the generator runs continuously under the drive of a power source such as a fuel motor, a steam turbine, a water turbine or other similar devices. So as to achieve the purpose of power generation. [0003] The generator is mainly composed of two parts, the stator and the rotor. The rotor is mainly composed of the rotor body and the magnetic bodies (permanent magnets or electromagnets) arranged in sequence on the surface, and the stator is mainly composed of the stator body made of ferromagnetic materials. 1. Composed of wire slots set on the stator body and armature windings composed of conductor coil winding wire slots, the rotor of the ge...
