Strong magnets are an essential component in several renewable energy technologies, including wind turbines, electric vehicles, and generators. These magnets are usually made from rare earth elements such as neodymium, dysprosium, and samarium.
In wind turbines, strong magnets are used in the generator to convert the kinetic energy of wind into electrical energy. The generator contains a rotor that rotates when the wind blows, and the rotor is fitted with strong magnets that produce a magnetic field. As the rotor turns, the magnetic field passes over a set of stationary coils, inducing an electrical current in the coils.
Similarly, in electric vehicles, strong magnets are used in the electric motor to produce torque, which rotates the wheels. The motor contains a rotor fitted with strong magnets that produce a magnetic field. When an electric current is passed through the stator coils, it interacts with the magnetic field produced by the rotor, causing the rotor to rotate and produce torque.
Strong magnets are also used in generators that convert energy from sources such as tidal, hydro, and geothermal into electrical energy. These generators work on the same principle as wind turbines, with the rotor rotating in response to the flow of water or steam and inducing an electrical current in the coils.
Overall, strong magnets play a crucial role in several renewable energy technologies, helping to produce clean and sustainable energy.
Permanent Neodymium Wind Generator Magnets
It is sintered neodymium magnet, it is a powder metallurgy technique.The smelted alloy is made into powder and pressed into a compact in a magnetic field. The compact is sintered in an inert gas or vacuum to achieve densification. In order to improve the coercivity of the magnet, an aging heat treatment is usually required.
