Green energy resource

Magnets play a very important role in the renewable energy market. Magnetics find their way in solutions for wind, tidal and wave energy. By using magnets and magnetic solution you can reduce or even eliminate the gearbox in wind turbines. Wind turbines working environment is very bad, it must be able to withstand heat, cold, wind, humidity and even salt spray test.

Typical Application Case

Renewable energy 

Design life of the wind turbine is generally two years. At present, both small wind turbine and a megawatt-class wind turbines are mostly optional permanent magnet NdFeB magnets, therefore, requires wind turbine magnet has good temperature stability, corrosion resistance, and high uniformity reliability.

The recent explosion of the wind turbine market across the globe has forced manufacturers into reducing manufacturing costs, improving efficiencies, and creating robust designs that do not require constant service.  Using a properly designed permanent magnet within the wind turbine generator will improve efficiencies in the conversion of wind power to electrical power immensely over induction, or wire wound, generators.  Also, selecting the correct magnetic material and manufacturing it to the proper specifications will ensure that it can be resistant to demagnetization due to high temperatures.

The next generation of wind turbines are currently being researched which use permanent magnet generators and axial flux couplings, which use permanent magnets as a coupling.  The overall purpose of this design is to increase efficiency by reducing friction.  Magnetic couplings are currently used in many applications, but this is a new one that is being explored and has great possibilities. UMAG Magnet electronic provide wind turbine magnet - high quality neodymium magnets used in large scale in commercial wind turbines to ensure high energy-efficiency and good reliability for the whole generator systems.


Electric car

When it comes to electric cars, magnets are essential.

Magnets are a primary component in electric motors. In order to work they need to be made of a coil of wire that can spin and is encircled by strong magnets. When an electric current is induced in the coil, it emits a magnetic field, opposing the magnetic field emitted by the strong magnets. It follows the same attraction and repulsion rules of magnets. For instance, when you put the north and south poles of two separate bar magnets an invisible force will push them away from each other. The same concept occurs in motors, but they are modeled in a way that the repulsion is used to control an energy source. This repulsion causes the coil to spin or rotate at a high speed. The coil is attached to an axle that allows the wheels to move.
