The technologies that are propelling convenience in society, such as machines that generate
wind energy, are continuing to mature, enabling a wide range of industries to produce more for less.
Magnetic engineering partners with wind industry for improved efficiency
Windpower Engineering reported that
permanent magnet generators (PMG) are transforming the way that wind-powered energy is distributed across the industries. Unlike legacy power sources, the reliability of PMG is providing energy developers with a technique that no longer requires the need for an electrical current to power the collection device. According to the source, the efficiency of this topology is making it easier for wind-powered generators to develop unique ways for providing a constant flow of energy to the rotor axis.
The need for reliability increases as the desire for output rises. Essentially, as more companies choose wind-powered solutions, developers of these technologies must determine the best methods of generating energy for their clients. Therefore,
strong magnets and the fields they create are used in different ways to meet these challenges.
Different techniques for optimum effects
Attaching the magnetic field to different constituent parts of the machinery is one approach that providers are utilizing. Instead of restricting themselves to the same configurations for power generation, the source noted that energy developers affix rotors with a permanent magnetic energy source to mitigate the need for a high-concentrated current of electricity, which also makes the addition of brushes unnecessary.
Cooling the machinery is another solution provided by PMG. As the conductivity of electricity is no longer a concern in the structure of these strategies, the need for radiators or heat exchangers lessens or, in some cases, removed entirely. This ultimately reduces the cost of construction and reduces the weight of the structure. Although similar in strength to
cube magnets or
disc magnets, the axial flux design requires high-potency magnetic fields to be effective.
According to the International Energy Agency (IEA), the use of
wind-based energy is expected to rise from 15 to 18 percent between the end of 2013 and 2050. Although there are barriers, such as determining the best construction methods for these projects, the source notes wind energy technologies are increasingly more accessible.
