Direct-drive PMG systems reduce mechanical losses and increase operational lifespan, further enhancing adoption in the sector.
Government incentives, renewable energy policies, and investments in sustainable power generation are reinforcing demand As wind energy continues to play a pivotal role in the transition to clean energy, the wind turbine systems segment is expected to remain the primary driver of growth in the Permanent Magnet Generators market, supported by technological innovation and increasing turbine installations worldwide.
The rate of consumption of conventional energy sources is expanding day by day. This has presented non-conventional energy sources as an alternative to traditional energy sources. Renewable energy sources, for example, wind, solar, biogas, small-scale hydro power plants, etc
. provide enhanced ecological protection. Declining fossil fuels supply and the damaged environment, which in some ways can be blamed on the conventional energy sources, have made it more important to discover other energy sources. Permanent magnet generators are becoming more popular day by day. They renewable are used to convert mechanical energy produced by rotor blades to electrical energy.
The energy conversion is based on Faraday’s laws of electromagnetic induction, that dynamically induces an electro-motive force i.e. e.m.f into the generators coils as it rotates. In permanent-magnets generators, permanent magnets are incorporated in the conventional rotor of an induction generator. Since these generators do not leave behind any residue or untreatable waste, they are fast becoming an extremely popular choice.
Permanent magnet generators are widely used in small wind turbines. These days, they are also being used in large offshore and onshore wind turbines.
These generators are superior replacements of traditional induction motors and can easily be attached with diesel generators, turbines and hybrid vehicles. These generators can also be utilized as part of wind as well as water machines. Some of the advantages of permanent magnet generators are self-protection against short circuits and severe overloads and easy maintenance.
The permanent magnet generators can be a direct current voltage machine with a rotary collector and brushes or an alternating current synchronous multiphase machine where the rotor and the stator magnetic fields are rotating at a similar speed. This removes the excitation losses in the rotor, which generally amount to 20% to 30% of the collective generator losses.
The reduced losses additionally give a lower temperature rise, which essentially means that a simpler and smaller cooling system can also be used in the generator. In case of permanent magnet AC synchronous generator, the inductor is located at the rotor whereas in permanent magnet DC generator, the inductor which consists of a coil or wire loop is set up at the stator with a group of permanent magnets.
In general, direct current permanent magnet generators are a preferred choice for wind turbine systems that operate at a small scale as they can work at low rotational speeds and give high degree of reliability with minimum maintenance costs. Their cut-in point is genuinely low and thus, they are also able to provide good proficiency particularly in light wind conditions.
