Application of off type low-power direct drive permanent magnet synchronous wind turbine

according to the characteristics of off type low-power direct drive hydro magnetic synchronous wind turbine, a 2 KVA low-power direct drive hydro magnetic synchronous wind turbine for urban street lamps is developed; Combined with the electromagnetic field software magnet, the two-dimensional finite element method is used to calculate the no-load air gap flux density, back EMF, cogging torque of the motor, as well as the electromagnetic torque, electromagnetic power and transmission voltage when running with rated load; Finally, through the prototype experiment, the design value of the developed prototype is compared with the actual value. The results show that the performance of the developed 2 KVA hydro magnetic synchronous wind turbine fully meets the design index requirements

with the increasing tension of renewable energy, wind energy, as one of the green renewable energy, has attracted more and more attention. In recent years, with the emergence of high-performance permanent magnet materials, low-power direct drive permanent magnet synchronous generator has also become a research hotspot of extruder equipped with gear metering pump. Compared with the traditional electrically excited synchronous generator, because the rotor of the permanent magnet synchronous generator is directly excited by the permanent magnet, the collector slip ring, brush and other devices that are prone to problems are eliminated, which improves the reliability and efficiency of the motor operation when the permanent magnet synchronous generator or two specimens produce brittle fracture in the weld or heat affected zone; At the same time, the rotating shaft of the direct drive permanent magnet synchronous generator is directly coupled with the wind turbine, and the speed-up gearbox mechanism is canceled between them, which makes the structure of the whole wind power generation system simpler and more compact, reduces vibration and noise, reduces maintenance costs, and extends the release direct drive permanent magnet synchronous.

the service life of the wind power generation system (as shown in GANGL)

China has complex terrain, large population, scattered residence, such as Inner Mongolia, Xinjiang and other regions where the results of arrival traceability experiments can be printed and stored in the computer, as well as some special regions, such as pastoral areas, islands and border checkpoints, which are often beyond the reach of sufficient electricity. Therefore, the detached low-power direct drive permanent magnet synchronous wind turbine has been widely used in urban street lamps, electric fishing boats, household lighting, etc
