Permanent NEO magnets and wind energy Magnet
Within the past decade or so, some wind turbines have been upgraded to utilize direct drive permanent magnet generator (PMG) systems, which has eliminated the need for gearboxes. Permanent magnets systems are used because they can be more cost-efficient, reliable and low-maintenance. Instead of needing electricity to emit a magnetic field, large neodymium magnets are usually used to produce their own. This eliminates the need for some parts that previous generators required and decreases the wind speed needed to produce energy.

Permanent magnets (PMs) are vital components of many electromechanical machines and electronic devices, but they are usually hidden in subassemblies. System designers and end users often give no thought to how choice and use of the permanent magnet material affect performance, size, and cost of the product. This paper describes the range of materials and properties now at the disposal of design engineers and the place of different magnets in electro-technology, with attention to engineering and economic aspects.
Revolutionary developments have recently occurred in the old field of permanent magnetism. Hard ferrites became an abundant inexpensive magnet material while the rare-earth magnets raised the highest available energy products 4 to 5-fold and coercivity by an order of magnitude. As a consequence, a rapid broadening of magnet uses is now occurring; traditional devices are miniaturized, new applications and design concepts are evolving. Trends and examples are discussed in this paper.
A confluence of recent developments in magnets, power semiconductors and microprocessors is particularly fruitful in the area of drives and motion control.
We also assess currently evolving permanent magnet materials. production processes, prospects for new, still “better” magnets, as well as ultimate upper limits for permanent magnet properties.
Today’s wind turbines have become highly complex pieces of machinery. Each part plays a significant role in how it functions and captures wind energy. The basic premise for how wind turbines work is that strong winds turn the blades, and the blades of the fan are connected to a main shaft in the center. Connected to that shaft is a generator that can convert that motion into electricity. Certain conditions are needed for this, which is why wind turbines are built to certain heights.
