Background technology
Small-sized AC permanent-magnetic generator has two kinds of radial magnetic field pattern and tangential magnetic field patterns according to the difference of main field direction, and the plane, magnetic direction place of the two is all vertical with rotating shaft (line).When existing permanent magnet generator was used for wind power generation, what adopt usually was the structure of magnetic direction and axis normal.As the more advanced Guangzhou of present technology red hawk Hy-400W wind-driven generator and Huaian, Jiangsu FD
2.7-500 permanent-magnetic wind driven generators all are structures of magnetic direction and axis normal.The permanent-magnetic wind driven generator unilateral magnetic force of this structure is big, and leakage field is many, and stator winding embeds according to certain rules in core slots simultaneously, and because of slot effect, electromagnetic torque can produce pulsation during motor rotation.Thereby the permanent-magnetic wind driven generator rated wind speed of this structure is all higher, and (10～12m/s), the fan blade diameter is bigger than normal, and under the less situation of wind speed, power output is little, can not utilize wind energy well.
Summary of the invention
The present invention aims to provide and a kind ofly can export bigger power under low wind speed, little air quantity situation, and it is wide to adapt to wind speed range, the permanent-magnetic wind driven generator that operational efficiency is high.
That axial magnetic field permanent magnet wind generator of the present invention adopts is two (on, the axial magnetic field structure of rotor down), comprise main shaft, stator and last, the lower rotor part end cap, stator is injection molded in stator disk by the concentrated stator coil circumference uniform distribution of several hollow-core constructions, slotless does not have iron core, on, the lower rotor part end cap is respectively by last, lower rotor part magnet steel and last, lower rotor part back of the body yoke is formed, on, lower rotor part magnet steel polarity is staggered to be distributed in, in the lower rotor part end cap disk, on, the lower rotor part end cap is connected by cylindrical casing, stator is fixed on the main shaft, on, lower rotor part end cap and stator constitute two air gaps, on, the lower rotor part end cap is connected with wind wheel by aluminium alloy structure, directly by the fan blade driven rotary.Motor integral body is flat-disk shape structure.
Axial magnetic field permanent magnet wind generator main magnetic circuit of the present invention is from a utmost point, axially pass air gap and another utmost point on the other side, along circumferentially passing adjacent magnetic pole and axial air-gap again through rotor back of the body yoke, at last along the rotor yoke closure, magnetic direction and parallel axes, overcome unilateral magnetic force, reduced leakage field, the close distribution of magnetic is more even under the pole-face, made full use of permanent magnetic material, air gap flux density improves about 10% than monohedral magnet structure, helps promoting motor performance, reduces cost, reduced volume.
The anodontia slotless of stator does not have iron core, and is simple in structure, and control is flexible, and moment of inertia is little, and torque pulsation is greatly improved, and response speed is fast.
During the rotor rotation, permanent magnet has the fan effect again concurrently, helps the heat radiation of motor.
For further improving the wind speed accommodation of motor, stator can adopt variable-pole winding, multiple output mode is set, on rotor, be provided with speed probe, control the stator coil transfer relay by the real-time speed signal (instruction) that speed probe sends, the connected mode of automatic switchover stator coil satisfies the requirement of the interior high efficiency running of wide wind speed, broad power band generating from low speed to high speed.
Axial magnetic field permanent magnet wind generator of the present invention can be exported bigger power under low wind speed, little air quantity situation, it is wide to adapt to wind speed range, the operational efficiency height.
