Wind power classification:
According to the output capacity of wind turbines, wind turbines can be divided into small, medium, large, megawatt series.
1、 Small wind turbine refers to the wind turbine with the capacity of 0.1 ~ 1kW.
2、 The medium-sized wind turbine refers to the wind turbine with a generator capacity of 1 ~ 100kW.
3、 Large scale wind turbine refers to the wind turbine with the capacity of 100 ~ 1000kW.
4、 Megawatt wind turbines refer to wind turbines with a capacity of more than 1000.
Permanent magnet direct drive wind turbine
1. Permanent magnet direct drive wind turbine
Direct driven wind turbine generators is a kind of direct driven generator by wind power, also known as gearless wind engine. This kind of generator adopts the way of multi pole motor directly connected with impeller to drive, without the traditional component of gearbox. Because the gearbox is a component with high overload and premature damage rate in megawatt wind turbine, the direct drive wind turbine without gearbox has many advantages, such as high efficiency, low noise, high life, reduction of unit volume, reduction of operation and maintenance costs, etc.
