Post Assembly Magnetization for the Automotive Sector

Magnet Applications
Post Assembly Magnetization for the Automotive Sector-Bunting-DuBois

Magnets are a critical component of every modern vehicle on the market today. Magnets do many different things that contribute to a vehicle’s function. You may find a magnet helping to form the traction drive to provide motive power to the vehicle, assisting in powering electric windows and windshield wipers, or contributing to the function of key sensors in the vehicle. Particularly in electric vehicles, magnets are fundamental.

In vehicles, magnets are incorporated into assemblies that go on to be used in key vehicle components such as motors. In some cases, magnet assemblies are built on-site by the vehicle manufacturer, but more commonly, companies will seek out specialist magnet suppliers such as Bunting-DuBois.

In many cases, the magnets going into a magnet assembly have already been magnetized. However, in some situations, using pre-magnetized magnets can be dangerous. Additionally, doing so can lead to roadblocks in packing and transportation down the line. In particular, large charged magnets are prone to causing these types of issues. Fortunately, there is a solution.

Post Assembly Magnetization

In order to improve safety and simultaneously simplify the manufacturing process, the technical engineering team at Bunting-DuBois has developed technology for post-assembly magnetization. In this process, a complex magnet assembly is constructed unmagnetized, then charged.

Post-assembly magnetization has many advantages. When using a post-assembly magnetization process, one of the results is that constructing the magnet assembly is easier and takes less time to complete. Additionally, it reduces the risks of mistakes occurring during assembly, such as incorrect polarity orientation. When a post-assembly magnetization route is taken, it means that the magnetic field and polarity will be exactly as required for every magnetic component. Because of post-assembly magnetization’s ability to ensure superior component consistency, it is ideal for the automotive sector.

Types of Magnet Assembly

There are many different types of magnet assemblies for the automotive industry, which is largely due to the many different automotive applications that magnet assemblies are used in. Depending on the application, a magnet assembly may require high-strength rare earth magnets, but lower strength ferrite magnets may just as well be the best fit for a given application’s requirements. Another example of variation is that a magnet assembly may have internally positioned magnets, or, it may have surface mounted magnets instead.
