There are permanent magnets and electromagnetic devices. Goldwind's 1.5MW and 2.5MW are permanent magnets. There are not many manufacturers of permanent magnet direct drive fans, most of which are testing machines that have mass-produced them, and Sinovel. The megawatt wind turbine is dual-powered electromagnetic, which is also a relatively mature technology. Direct drive and dual power supply are currently the two main development directions of wind power. Direct drive wind turbines do not have gearboxes and the speed of the generator is electromagnetic. Wind turbines have gearboxes and motor speeds typically around 1,500.
