Air Core Gauge

2023-06-19T17:36:38+00:00Injection Molded Parts, Manufacturing, Uncategorized|

Our customer was producing air core gauges using an older process using ceramic magnets. The magnet was zinc die cast onto a small, precision shaft. This presented several problems. The ceramic magnets often cracked and require precision grinding to fit into the cavity of the die cast machine to be assembled, which was expensive. Even

Great Magnet Design – Contact Free Ring Assembly

EAM is known for innovative magnet designs – here is another great example: The Challenge: Produce an inner and outer ring assembly for use in an auxiliary HVAC power unit for trucks. The power unit incorporates a J1939 bus and new operating modes aimed at saving battery power and fuel.  An integrated pump circulates heated coolant

Magnetic Assemblies – Higher Quality, Lower Cost!

Most magnet assemblies are made the old fashioned way – by gluing the magnet(s) to a backing plate, shaft, hub, housing, etc. This adds an extra step to the process and can potentially lead to defects and quality issues. EA Magnetics can help you save time and money by eliminating these issues. Here’s a great

Replace Magnets That Can’t Currently Source Offshore

2023-04-18T18:06:02+00:00Injection Molded Parts|

A well-known sensor manufacturer wanted to replace an existing magnet they were getting in China with one produced domestically. EAM worked with the customer to design a larger injection molded magnet that can snap in a case and actuate a TMR sensor used in security applications. The customer was able to re-shore this part easily

Why choose EA Magnetics over other magnet suppliers?


Quality Certification: Top suppliers will be certified to a quality standard – the best will be certified to a rigorous industry specific standard like IATF 16949:2016. EAM was among the first magnet manufacturers in the US to earn IATF 16949 certification. Manufacturing: Most magnet companies you find online are strictly distributors. The majority import magnets

Magnets with Multiple Poles


Some magnet applications require the use of magnets with multiple poles. Multi-pole magnets are used in motors, linear actuators, hall effect applications, and more .  For many years manufacturing multi-pole magnets was not easily accomplished, so many designs used multiple magnets positioned in an assembly to create a multi-pole effect. This is, of course, a

Innovative Hybrid Motor Magnet

Here’s a great example of an automotive related linear motor application. The magnet in this case is a multi-pole injection molded magnet made from a hybrid neodymium and ferrite blend. The magnet is injection molded directly to a zinc plated steel hub – no gluing or assembly required. The hub is knurled to promote the

Electric Cars 101: How EV Motors Work, Tech Differences, and More


How Electric Cars Work: Motors. It has to do with magnetism and the natural interplay between electric fields and magnetic fields. When an electrical circuit closes allowing electrons to move along a wire, those moving electrons generate an electromagnetic field complete with a north and a south pole. When this happens in the presence of

Roll Out Your Meditation Mat & Turn on the Magnetics


FluxWear, a neuromodulation technology startup located in southern California, demonstrated its first product at the 2022 Consumer Electronics Show in Las Vegas in January. The product, SHIFT, is a wearable neuromodulation device to help people with pain, anxiety or stress to rapidly attain a meditative state. SHIFT is designed to deliver a unique magnetic stimulation
