Use of Magnetics parts in the Automotive Sector

The complexity of car electrical control systems has increased significantly as automobile manufacturers respond to the requirement to build vehicles that use less fuel, emit less pollution, and are more competent. This has raised the need for automotive solid magnets to produce vehicle actuators and motors. As a result, the demand for rare earth metals to make compact and robust samarium cobalt (SmCo) and neodymium magnets (NdFeB) with complicated forms and geometries has increased.

Vehicle control systems have shifted from mechanical, pneumatic, and hydraulic control to electrical control during the previous few decades. This, in turn, has increased demand for magnets used in rotors, sensors, valves, and stabilization systems to improve vehicle control mechanisms. These applications include:

  • Sensors include ABS speed sensors, position sensors, airbags, seat belt sensors, and engine control sensors.
  • Motors include fans, starters, alternators, power steering, windshield wipers, seat motors, and drive motors.
  • Actuators include fuel injectors, vents, brakes, cruise control, doors, and suspension.

 Although classic ferrite magnets are still widely used, the demand for small high-performance magnets has raised the need for vehicle magnets. Examples include neodymium magnets, samarium magnets, aluminum alloy magnets (Alnico), and plastic-bonded magnets. Even though these new magnetic nanoparticles are formidable, many are temperature sensitive.

For example, the most powerful neodymium magnets, manufactured from an alloy of neodymium, iron, and boron, lose their magnetic around 80 °C. However, by modifying the alloy composition, the maximum magnet working temperature may be increased to roughly 250°C, but at the expense of magnetic strength.

Sintering, casting, and molding with plastic fillers are all methods employed in magnet manufacturing. The technique of production selected is determined by the eventual application of the magnet, which includes:

  • Cost
  • Strength of the field
  • Shape
  • Temperature

Recrystallization is commonly used to create high-power neodymium and samarium magnets. The components are melted, cast, and crushed into a fine powder in a furnace. Then, utilizing presses, the powder is routed into the desired form. Finally, the magnets are welded and magnetically attached in a special vacuum furnace. It should be noted that neodymium magnets are corrosive and require a special covering. Other procedures employed in the magnet factory include traditional casting techniques and magnet encapsulation in plastic materials.


The automobile industry continues to require new and improved magnets for cars that can operate well in adverse environments. This encourages research into improved methods of creating high-performance magnets for the automobile sector.
