50 percent. Direct drive permanent magnet generators for wind power have become the dominant technology in the wind power industry. Their advantages include simple structure, high reliability and high conversion efficiency. In 2022, with the continued development of technology and further cost reduction, wind energy. Direct drive permanent magnet generators will be further popularized and increased. Depending on the specific conditions of each region, the proportion of new direct-drive permanent magnet generators for wind power will exceed 50%.
There are permanent and electromagnetic magnets. Goldwind's 1.5 MW and 2.5 MW are permanent magnets. There are not many permanent magnet direct drive fan manufacturers, most of them are test machines that Goldwind has already mass-produced. them. Production, Sinovel's megawatt wind turbines are 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 generator speed. is low, while electromagnetic wind turbines have a gear box, the motor speed is generally around 1500.
