Abstract
The utility model discloses a pitch control magnetic encoder of a wind power generator. The pitch control magnetic encoder of the wind power generator is characterized by comprising a magnetic stripe which is arranged on a pitch control flange plate and a magnetic head which is arranged at the static portion of a pitch control bearing, wherein the pitch control flange plate and the pitch control bearing coaxially move. The magnetic stripe is fixed on the pitch control flange plate through a magnetic stripe installation cover plate. The pitch control magnetic encoder of the wind power generator with the magnetic encoder has the advantages of being high in precision, strong in antijamming capacity, easy to install, convenient to debug, capable of saving a certain utilization space, low in cost and long in non-contact service life. The pitch control magnetic encoder of the wind power generator conducts refined calculation and control of an actual pitch changing angle, thereby benefiting improving actual generating efficiency.
Description
[technical field]
The utility model relates to the wind-driven generator pitching magnetic coder.
[background technique]
Become the oar magnetic coder and be used for calculating the actual change propeller angle of blade and becoming oar speed, in order to according to actual wind speed the blade angle is adjusted, finally reach maximum generated output and catch.Become at present the traditional rotating speed coder of the many employings of oar encoder, precision is low, be generally 0.5-1 °, and the small gear of rotating coder need to the pitch variable bearings flank engagement, easily wearing and tearing are vibrated greatlyr, and electrical signal also easily is subject to system interference, this has just limited its working life and control accuracy, integrating error easily occur.Rotating speed coder also has certain requirement to installing space in addition, takes up space large, and cost is high.The utility model is exactly the improvement of making under this background.
[model utility content]
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of change oar encoder control accuracy high, simple wind-driven generator pitching magnetic coder easy to install.
The purpose of this utility model is achieved in that
The wind-driven generator pitching magnetic coder is characterized in that it comprises to be installed in the magnetic head that becomes the magnetic stripe on the oar flange plate and be installed in the bearing stationary part with pitch variable bearings concentric motion; Described magnetic stripe is installed cover plate by magnetic stripe and is fixed on the change oar flange plate.
Aforesaid wind-driven generator pitching magnetic coder is characterized in that described change oar flange plate is provided with groove, and magnetic stripe is located in the groove.
