Abstract

Disclosed is a low-rotation-speed off-network wind power generator, comprising a stator, a rotor, a conductive wire and fan blades. The fan blades are welded with the outside of the rotor. The stator shaft is connected with the rotor through a bearing. A silicon-steel plate on the stator is grooved with a slant groove. Winding coils are arranged like an S along the slant groove. The utility model which has simple structure, small size, steady output power, long service life and high reliability can achieve low rotation speed electricity generating and is applicable for various wind power generation situations.

Description

Low rotary speed off-net wind-driven generator
The utility model relates to a kind of wind-driven generator.
At present, conventional wind power generator all adopts inner rotor core, requirement rotating speed height, so need have speed increasing mechanism, make that like this generator volume is big, weight is big, complex structure, the cost height, the processing maintenance is very inconvenient, if adopt outer-rotor structure then often can not realize slow-speed of revolution generating, China Patent No. is 95201695.8 patent application, adopt external rotor, the coiling group on the stator radially or axial distribution, the coiling group is the open loop square wave, this generator can be realized slow-speed of revolution generating, and volume is little, and is simple in structure, but because this generator adopts internal-combustion engine, pto is in central authorities, and drive the axle that flies that hangs, and poor stability when making its running, the position between the rotor is difficult to guarantee, thereby be difficult to export stable electric current and voltage, the cutting magnetic field when split coil of axial distribution makes whole section simultaneously, inrush current is big, the long-term use working life that can influence generator.
The purpose of this utility model is to overcome the deficiency that above-mentioned known technology exists, thereby provides a kind of mechanism simple, and output power is stable, the low rotary speed off-net wind-driven generator of long service life.
The purpose of this utility model realizes in the following way:
This generator is by stator (1), rotor (6), lead (11) and fan blade are formed, its rotor (6) outer and blade welding, two ends of rotor seals stator (1) by rear end cover (2) and front cover (17), stator (1) center has axle, this axle passes rotor rear end cover center, this also has center hole and passes for the lead (11) on the stator coil, rotor (6) connects with stator axis by the bearing on the front and rear cover (12), have silicon steel plate (22) on the stator frame of stator (1), fixing with stator frame by key (23), one side also has back-up ring (24), silicon steel plate tilts with stator shaft orientation and forms parallel skewed slot (25), and winding coil is along the S-shaped arrangement of skewed slot.
Skewed slot (25) can be 2~8 ° with the axial angle of stator (1).
Rear end cover (2) has sealing cover (19) at the opening of stator axis.
Lead (11) is fixed on the stator frame by ply-yarn drill (10).
Rear end cover (2) has bearing door (13) in the end of stator axis.
Rotor inner wall along the circumferential direction has permanent magnet, and is separated with air gap between the stator.
During work, blade drives the rotor rotation, and the magnet in the rotor forms rotating magnetic field, and the stator coil cutting magnetic line produces electric current and exported by lead.
The utility model compared with prior art has following advantage:
Can realize slow-speed of revolution generating, reduce speed increasing mechanism, simplify the structure, reduce volume and weight, blade and rotor link, and can increase the rotating shaft diameter when reducing volume, thereby have increased structural strength, can increase the service life effectively.In addition, the oblique arrangement of coil can make line segment cutting magnetic line gradually, neither reduces generated output, has reduced inrush current again, thereby has prolonged the working life of coil.The utility model structure is compared with the flywheel transmission and has been reduced vibration and noise in addition, has guaranteed the stability of position between the stator rotor simultaneously, makes the electric current and voltage of output reliable and stable.
The utility model is described in further detail below in conjunction with accompanying drawing:
