Embodiment 1

[0028] refer to Figure 1 to Figure 4 , the magnetoelectric composite power generator of the present invention comprises shell 1, shaft center starter motor 2, inner layer permanent magnet stator 3, intermediate rotor 4 and outer layer permanent magnet stator 5 and is used to start the start of shaft center starter motor 2 source. The rotor center shaft 21 of the axial starter motor 2 is rotatably mounted on the casing 1 through the first bearing 6, and the inner permanent magnet stator 3, the intermediate rotor 4 and the outer permanent magnet stator 5 are centered on the axial starter motor 2 along the radial direction. set in sequence.

[0029] The inner layer permanent magnet stator 3 includes an inner stator frame 31 and a plurality of inner stator magnetic blocks 32 fixed on the inner stator frame 31 and arranged sequentially along the circumferential direction. The outer layer permanent magnet stator 5 includes an outer stator frame 51 and a plurality of outer stator ...

Embodiment 2

[0036] refer to Figure 5 , the difference between this embodiment and Embodiment 1 is: the shaft center starter motor 2 adopts an outer stator permanent magnet synchronous motor that can be switched between the two operating modes of the motor and the generator, and includes an outer stator 22, an inner rotor, and an outer stator 22 It is a permanent magnet stator, and the inner rotor includes a rotor central shaft 21, a rotor permanent magnet 25, and a cage-shaped rotor winding 26 sleeved on the outer periphery of the rotor permanent magnet 25, and the cage-shaped rotor winding 26 is connected with an electric energy output circuit. The cage-type rotor winding 26 is fitted on the outer periphery of the rotor permanent magnet 25 , which is equivalent to setting a winding coil on the outer stator 22 . The starting source adopts an external power supply for the axial starter motor 2. The external power supply includes an energy storage battery, an energy storage capacitor, and ...

Abstract

The invention relates to a magnetoelectric hybrid power generator which comprises an axis starting motor, an inner-layer permanent magnet stator, a middle rotor and an outer-layer permanent magnet stator which are sequentially arranged in the radial direction. The inner permanent magnet stator and the outer permanent magnet stator respectively comprise a plurality of stator magnetic blocks which are sequentially arranged along the circumferential direction, the stator magnetic blocks are inclined at a certain angle relative to the radial direction, and a magnetic track is formed between the inner permanent magnet stator and the outer permanent magnet stator; the middle rotor is arranged in the magnetic rail and is synchronously and rotationally connected with a rotor middle shaft of the axis starting motor, and the axis starting motor can be switched between a motor working mode and a generator working mode. After the axis starting motor is started, the inner-layer permanent magnet stator, the outer-layer permanent magnet stator and the middle rotor are guided to do work, the middle rotor rotates in the magnetic rail, torque is fed back to the axis starting motor, the boosting torque is outputted and is converted into a generator, and magnetomotive power generation is achieved. The magnetoelectric hybrid power generator has the advantages of high torque density, high magnetic energy utilization rate, high output power, high power generation efficiency, energy conservation, environmental protection and good economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a magnetoelectric composite power generator. Background technique [0002] The energy shortage in the world today is becoming more and more scarce. In the future, human beings will face a very severe energy shortage crisis. The commonly used coal power and hydropower are also in serious shortage. The common coal resources and water resources are non-renewable resources, and the price of coal is getting higher and higher. , and a large amount of carbon dioxide is produced in the process of power generation, causing air pollution, which is extremely unenvironmental, causing great harm to human production and life, and water resources are increasingly scarce. Wind power and solar energy are limited by terrain and regional conditions. What is frightening is that all countries in the world are vigorously developing nuclear power, and nuclear power pollution brings even more devasta...
