Abstract
The utility model relates to a wind driven generator, in particular to a head rotor of the wind driven generator. The head rotor of the wind driven generator comprises a rotor core and a rotor shaft installed in the rotation center of the rotor core, and is characterized in that the external circular surface of the rotor core is evenly distributed with 12 long grooves with ''V''-shaped cross sections along the axial direction of a rotor, wherein permanent magnets with ''V''-shaped cross sections are fixedly installed in the long grooves, the outer surface of the rotor core is wrapped with a non-magnetic-conductive material, a stator core corresponding to the rotor is evenly distributed with 36 grooves, and stator windings are installed in the grooves. The technical scheme of the utility model is that the permanent magnets in the rotor are designed into a "V" shape, thus the permanent magnets have the advantages of radial magnetizing and horizontal magnetizing, effectively concentrating the magnetic flux, and improving the torque and power generation performance at medium and low speed of the motor. The embedded type permanent magnet rotor structure changes the quadrature and direct axis magnetic circuits of the motor, thus the power generation performance at medium and low speed and the output power of the wind driven generator are greatly improved and enhanced.
Description
Technical field
The utility model relates to a kind of wind-driven generator, particularly wind power generation machine head rotor.
Background technology
Along with scientific and technological development grows with each passing day to the demand of electric power, and a large amount of exploitations of fossil energy are increasing on the impact of environment.The utilization of regenerative resource becomes a developing direction that solves energy shortage and environmental pollution.In the very inaccessible areas of conventional electrical network such as some outlying mountain areas, farming and pastoral areas, small-size wind power-generating equipment, because it is easy to use, invest the features such as little, is applied gradually at present.But existing small-sized wind power generator is under the lower situation of wind speed, and the rudder on wind-driven generator cannot make to drive the fan blade surfaces of revolution of generator rotation vertical with the moving direction of wind, causes generating efficiency to reduce.
Summary of the invention
The purpose of this utility model is the defect that overcomes prior art, provides a kind of in the situation that wind speed is lower, can make in wind-driven generator the surfaces of revolution of fan blade and the moving direction of wind vertical, can effectively increase the rotatable rudder of wind-driven generator of generating efficiency.
The technical solution of the utility model is: a kind of wind power generation machine head rotor, comprise rotor core and the armature spindle that is arranged on rotor core pivot, it is characterized in that on the periphery of above-mentioned rotor core along being evenly equipped with the elongated slot that 12 cross sections are " V " shape on rotor axial, in elongated slot, be installed with the permanent magnet that cross section is " V " shape, outer surface at rotor core is enclosed with non-magnet material, on the stator core corresponding with above-mentioned rotor, be evenly equipped with 36 grooves, stator winding is arranged in groove.
Above-mentioned permanent magnet is Nd-Fe-B permanent magnet.
The technical solution of the utility model is that the permanent magnet in rotor is designed to " V " shape, and the existing radial magnetizing of permanent magnet, has laterally and magnetize again like this, and active set has suffered magnetic flux, improved motor moment of torsion and in, low speed power generation performance.From the characteristic of the magnetic circuit analysis of p-m rotor, built-in type permanent magnet rotor structure, has changed the cross, straight axle magnetic circuit of motor, can improve the governor control characteristics of motor, widens velocity interval, make the technical program in, low speed power generation performance and power output improve greatly.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, on the pivot of the rotor core 1 of wind-driven generator, armature spindle 4 is installed, on the periphery of rotor core, be evenly equipped with along rotor axial the elongated slot that 12 cross sections are " V " shape, in elongated slot, be installed with the permanent magnet 2 that cross section is " V " shape, permanent magnet adopts Nd-Fe-B permanent magnet, be enclosed with non-magnet material 3 at the outer surface of rotor core, be evenly equipped with 36 grooves on the stator core corresponding with above-mentioned rotor, stator winding is arranged in groove.
Claims (2)
1. a wind power generation machine head rotor, comprise rotor core and the armature spindle that is arranged on rotor core pivot, it is characterized in that being evenly equipped with along rotor axial the elongated slot that 12 cross sections are " V " shape on the periphery of above-mentioned rotor core (1), in elongated slot, be installed with the permanent magnet (2) that cross section is " V " shape, be enclosed with non-magnet material (3) at the outer surface of rotor core (1), on the stator core corresponding with above-mentioned rotor, be evenly equipped with 36 grooves, stator winding is arranged in groove.
