Description

A kind of disk permanent magnet generator
Technical field
The utility model relates to technical field of generators, especially a kind of disk permanent magnet generator.
Background technology
Wind energy is a kind of clean, environmental protection, regenerative resource, and the exploitation for wind energy become a lot of countries and regions and solve energy crisis important channel.
Along with the development of wind technology, Novel vertical axis wind turbine takes diverse design concept, adopt new structure and material, reach breeze start-up, noiseless, anti-more than 12 grades typhoons, the premium properties such as not affect by wind direction, can in a large number for the middle-size and small-size application scenario such as villa, multilayer structure.
Meanwhile, the disk generator being applicable to small-size vertical axis wind turbine urgently develops.
Utility model content
The utility model provides that a kind of profile is flat, axial dimension is short, iron-core-free, is applicable to the disk permanent magnet generator of small-size vertical axis wind turbine.
The technical solution of the utility model:
A kind of disk permanent magnet generator, is covered by upper end cover, main side and rotor, stator form.
Described rotor is connected with main shaft, together rotates in company with main shaft; Described stator is the round plate being stained with permanent magnet, and stator is attached to main side and covers.
Described rotor adopts iron-core-free structure, and coil encapsulation, in insulating material, is pressed into plate-like.
Described permanent magnet is 16 pieces of fan-shaped permanent magnet poles, and N magnetic pole and S magnetic pole are alternately uniformly distributed around round plate center.
The material that described upper end cover and main side lid adopt is steel, and it is in addition fastening that upper end cover and main side lid connecting portion arrange 16 screws.
The disk permanent magnet generator structure that the utility model provides is simple, profile is flat, axial dimension is short, coreless armature structure, and torque exports steadily, and there is not magnetic hysteresis and eddy current loss, efficiency is higher; Two ends of rotor face directly contacts with air gap, is conducive to heat radiation; Rotating part is only coil, and moment of inertia is little, has excellent fast reaction performance, is applicable to the occasion of frequent starting and braking.

Embodiment
The utility model is set forth further below in conjunction with accompanying drawing.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
The utility model is a kind of disk permanent magnet generator, as shown in Figure 1, is made up of upper end cover 1, main side lid 2 and rotor 3, stator 4.
Described rotor 3 is connected with main shaft 5 by connector 51, together rotates in company with main shaft 5, with reference to Fig. 2; Described stator 4 is for being stained with the round plate of permanent magnet, and stator 4 is attached on main side lid 2.
Described permanent magnet is 16 pieces of fan-shaped permanent magnet poles, and N magnetic pole and S magnetic pole are alternately uniformly distributed around round plate center, with reference to Fig. 3.
It is in addition fastening that described upper end cover and main side lid connecting portion arrange 16 screws, and with reference to Fig. 2, Fig. 3,16 screw aperture 21 that 16 screw aperture 11 and the main side of upper end cover 1 cover 2 are agreed with completely, one_to_one corresponding.
Preferably, the material that upper end cover 1 and main side lid 2 adopt is steel, and magnetic property is good, and two end cap closes the good magnetic circuit of rear formation.
Between permanent magnet pole and upper end cover 1, have working gas gap, the direction of magnetic field between air gap is axially.Main shaft 5 rotates between the air gap of rotor driven 3 between permanent magnet pole and upper end cover 1 and rotates, and cutting magnetic induction answers line, generation current.
