Abstract
The utility model discloses a support of an outer rotor perpendicular shaft type wind driven generator. The support comprises a base, static magnetic steel and dynamic magnetic steel. The base is used for supporting the outer rotor perpendicular shaft type wind driven generator, the static magnetic steel is fixedly coupled on the base, and the dynamic magnetic steel is fixedly coupled on a rotor of the outer rotor perpendicular shaft type wind driven generator. Through the support, the service life of a generator bearing can be prolonged, meanwhile, energy consumed for pushing the generator to rotate is reduced, and therefore the whole system efficiency of the wind driven generator is improved.
Description
Technical field
The utility model patent relates to a kind of external rotor perpendicular axis type generator, the particularly support of external rotor perpendicular axis type generator.
Background technique
Perpendicular axis type wind-driven generator, because the restriction and the operation that are not subject to wind direction time only produce very low noise advantage, makes it in the wind-driven generator of breeze type and low wind speed, be subject to increasing application.Make wind-driven generator in the time of gentle breeze and low wind speed, confess electric power as much as possible, the rotation power consumption of the few wind-driven generator of necessary Jin Ke Neng Minus, and the jacking force that the gravity of epitrochanterian wind wheel apparatus and wind produce is the main source of wind driven generator rotation power consumption.
Common perpendicular axis type wind-driven generator has base, comprises king-post and chassis, and the vertical core of king-post is used for holding stator main shaft, and chassis is used for being fixed on ground or other plane.Conventionally the effect of base is only to support generator and do not have the function that improves engine performance or reliability.
Model utility content:
The utility model discloses a kind of support of external rotor perpendicular axis type wind-driven generator, comprise the base (9) that supports described external rotor perpendicular axis type wind-driven generator, the magnetostatic steel (7) of fixed coupling on described base (9), and fixed coupling is at the epitrochanterian moving magnet steel (6) of described external rotor perpendicular axis type wind-driven generator, described magnetostatic steel (7) and described moving magnet steel (6) are configured to contrary magnetic pole power to placement.
The invention also discloses a kind of external rotor perpendicular axis type wind-driven generator, comprise the rotor (1) of Nd-Fe-B magnet steel is housed, by winding epoxy casting all-in-one-piece stator (2), and the support of external rotor perpendicular axis type wind-driven generator as above.
By using the utility model, can promote less at the Tong Shi Minus that improves dynamo bearing working life the rotation power consumption of described generator, thereby the efficiency that improves wind-driven generator whole system can also reduce the lower limit of wind energy to greatest extent uses model Wall, thereby improves the utilization factor of wind energy.

Embodiment
According to the support of an embodiment's of the present utility model external rotor perpendicular axis type wind-driven generator at the magnetostatic steel that supported on the base of generator fixed coupling, on the rotor of generator fixed coupling moving magnet steel.Magnetostatic steel and moving magnet steel are configured to contrary magnetic pole power to placing in opposite directions.The magnetostatic steel being fixed on like this on base allows whole generator system be suspended in the vertical core of base to the repulsion of moving magnet steel.This repulsion has been offset the gravity of generator amature and epitrochanterian all mechanical devices and the axial and radially most active forces of the jacking force of wind generation to the bearing of installing in generator.Thereby lacked at the Tong Shi Minus that has improved dynamo bearing working life the rotation power consumption that promotes described generator, and improving the efficiency of wind-driven generator, the lower limit that can also reduce to greatest extent wind energy uses model Wall, thereby improves the utilization factor of wind energy.
Fig. 1 shows according to the support of a kind of external rotor perpendicular axis type wind-driven generator of an embodiment of the present utility model, it mainly comprises the base (9) being made up of king-post and chassis, extended base tray (13) from the king-post of base, be arranged on the magnetostatic steel (7) in base tray, be fixed on the sleeve (8) rotating with rotor on generator bearing base, the moving magnet holder (14) extending laterally from sleeve, is directly fixed on the moving magnet steel (6) in moving magnet holder (14).
Also comprise electromagnetic brake (3) according to the support of external rotor perpendicular axis type wind-driven generator of the present utility model, comprise magnetic conductive shell (10), coil (11) and electromagnetic chuck (12), its coil (11) is placed in magnetic conductive shell (10), electromagnetic chuck (12) is directly fixed on the lower end surface of bearing support of generator, and magnetic conductive shell (10) is fixed on main shaft (5).Under strong wind or other External Force Acting, the rotating speed of generator exceeds on its trouble free service rotating speed in limited time, make coil (10) power supply that the output electric energy of generator switches to electromagnetic brake make it produce magnetic field by controller, thereby at upper electromagnetic attraction and the eddy current of producing of electromagnetic chuck (11), allow the rotating speed of generator be dropped rapidly to trouble free service rotating speed.So magnetic conductive shell does not contact not wearing and tearing with electromagnetic chuck, so just ensure that whole generator and its all additional devices (as fan blade and support etc.) are not damaged, thereby increased their working life.
In perpendicular axis type wind-driven generator, the main shaft of fixed stator, rotor, magnetic suspension bearing and brake (5) can move up and down in base (9), and by the straight pin on main shaft (5) and the collocation of the kidney-shaped slotted eye on base (9), main shaft (5) can not rotate.
Although provided exemplary characteristics of the present utility model above, it will be understood by those of skill in the art that in the situation that not deviating from theme required for protection, can carry out various amendments to the described specific embodiment of the utility model.Therefore, claimed theme is not limited to disclosed particular example, and on the contrary, it has comprised all the elements within the scope that falls into claims.
