Embodiment Construction

[0019] Such as figure 1 As shown, a double-stator permanent magnet generator of the present utility model includes a casing 1, and a stator, a rotor 17, a static shaft 15 and a moving shaft that is socketed with the static shaft 15 and can rotate axially are arranged in the casing 1 9. The moving shaft 9 drives and connects the rotor 17. The stator includes a concentric annular outer stator and an inner stator. The inner stator includes an inner stator core 12 and an inner stator winding 11. The outer stator includes an outer stator core 2 and an outer stator winding 3. The rotor 17 is located between the outer stator and the inner stator. Driven by the moving shaft 9, the rotor 17 rotates between the inner stator and the outer stator. The inner and outer surfaces of the rotor 17 are respectively provided with inner magnetic steel 7 and outer magnetic steel 4 . The rotor 17 is connected with a rotor bracket 5 perpendicular to the center line of the moving shaft. The moving s...

Abstract

The invention discloses a double-stator permanent magnet generator comprising a casing, wherein a stator, a rotor, a dead axle and a moving axle are arranged in the casing, wherein the moving axle is sheathed with the dead axle, is capable of axially rotating, and drive and is connected with the rotor; the stator comprises a stator iron core and a stator winding; the stator consists of concentric annular outer stator and inner stator; the rotor is positioned between the outer stator and the inner stator; and magnetic steel is covered on both the inner surface and the outer surface of the rotor. The invention has the advantages that two stators are arranged in one generator so that current is simultaneously generated in windings of the inner stator and the outer stator when the rotor rotates so as to fully utilize the inside space of the generator, greatly improve the power of the generator in effective volume space, avoid excessive enlargement of the volume when the efficiency of the generator is improved, reduce the cost and improve the utilization rate of wind energy. In addition, the rotor is provide with the inner magnetic steel and the outer magnetic steel so as to form an inner and an outer independent magnetic paths without interference so that the operation is stable.

Description

technical field [0001] The invention belongs to the technical field of generators, in particular to a double-stator permanent magnet generator. Background technique [0002] As a clean and renewable resource, wind energy has a very broad development prospect. Wind power generators are the [0003] A crucial core link in hair growth. In direct drive wind turbines, at present, the general way to increase the power of the generator is to increase the volume of the generator, but there are many conditions to increase the volume, and the cost is high. relatively low. Contents of the invention [0004] In order to solve the above technical deficiencies, the present invention provides a double-stator permanent magnet generator with high utilization efficiency of wind energy and relatively small volume and weight. [0005] The present invention is achieved through the following measures: [0006] A double-stator permanent magnet generator of the present invention includes a ca...
