About Arnold Magnetic Technologies

Based in Rochester, NY with an operating history of more than 125 years, Arnold is a leading global manufacturer of engineered solutions for a wide range of specialty applications and end-markets, including aerospace and defense, general industrial, motorsport, oil and gas, medical, and energy. From its Technology Center and manufacturing facilities located in the United States, the United Kingdom, Switzerland and China, the company produces engineered magnetic assemblies in addition to high performance permanent magnets, precision foil products and highly loaded composites that are mission critical in motors, generators, sensors and other systems and components.

Originally published in Electric & Hybrid Marine Technology.

Electric transportation poses pressing design and manufacturing challenges – one of which is its high-power requirements. The electrification of all transportation would require more power than a standard electrical grid could provide on top of current demands. Permanent magnet motors have increasingly become the motor of choice in various applications as they benefit from superior energy efficiency and power-to-weight ratio. The efficiency of these motors is especially advantageous in battery-powered systems. The automotive and marine industries have embraced these motors in powertrains due to their impressive power density, efficiency and compact size. Their brushless design offers improved reliability and longevity over traditional induction motor designs.

Material choices

When considering materials for high-performance PM applications, neodymium iron boron (NdFeB) and samarium cobalt (SmCo) are widely used due to their high magnetic strength. However, they differ in several key aspects that can influence their suitability for various applications.

NdFeB magnets exhibit higher magnetic flux than SmCo magnets, which means they can deliver more magnetic force. This makes such magnets suitable for applications that require higher torque output with lighter weights, such as electric vehicles and wind turbines. However, NdFeB magnets have a lower resistance to high temperatures and are more prone to corrosion, which may require additional thermal management or protective coating in certain applications.

On the other hand, SmCo magnets offer superior temperature stability and corrosion resistance. For example, Arnold Magnetic Technologies’ Recoma 35E SmCo magnet materials, the most power-dense samarium cobalt magnet available, are engineered for the most demanding environments including high speed (in excess of 100,000 rpm), high temperature (150-250° C) and highly corrosive environments.

Unlike neodymium (Nd) magnets, which need high levels of rare dysprosium (Dy) to function at moderate temperatures, SmCo magnets use materials that are more widely available and are stable at temperatures well above the Curie point of NdFeB. This makes SmCo pricing more stable and less prone to rare earth market changes.

When there are supply concerns, it’s crucial to source domestically when possible. Companies such as Arnold Magnetic Technologies offer a broad-based source of supply for samarium cobalt magnets’ materials, including samarium cobalt made in the USA. Plus, Arnold’s recent partnership with Cyclic Materials provides another supply source for these critical resources. Arnold and Cyclic Materials are creating the world’s first circular supply chain for rare earth materials through reclamation.

In applications where high power density is a must, efficiency must be maximized. Precision-rolled thin metals, L-type laminated magnets and more help customers achieve higher efficient and power gains in their motor and transformer designs. Arnold has played a pivotal role in the electrification of transportation since the invention of the electric train. Today the company works with its customers to pioneer electric propulsion systems for space, air, watercraft, motorsport vehicles and heavy equipment.

Also, Arnold’s recent partnership with Cyclic Materials of Kingston, Ontario will provide another supply source for these critical resources. Arnold and Cyclic Materials are contributing to the domestic economy by creating the world’s first circular supply chain for rare earth materials through reclamation.

In applications where high power density is a must, efficiency must be maximized. Arnold’s other products include precision rolled thin and ultra-thin metals which help customers achieve efficiency gains in their motor and transformer designs. Arnold’s materials offer more efficient use of electrical steel, resulting in higher power density and energy savings. For insulation purposes, Arnold’s non-grain oriented electrical steel, Arnon^®, offers the thinnest insulating layers with the lowest eddy current losses. Together, these elements maximize efficiency.

Arnold Magnetic Technologies’ Director of Engineering, Aaron Williams, will be presenting at the 2018 Motor and Drive Conference in Orlando February 8th.

This presentation will introduce permanent magnet concepts and calculating where the permanent magnet will operate in a magnetic circuit. Knowing where a permanent magnet operates allows us to determine what type of magnet would offer the best performance for a specific application. After designing the correct magnet for the application, the manufacturing process must be considered. Specifying a magnet by its maximum energy product is useful for magnet suppliers. Machine designers should also specify magnets based on their performance in the application. Aaron will conclude with a case study of a high speed machine and provide details on how to properly specify the magnet assembly.

If you plan to attend either the @MotorDriveConference or @Magnetics2018, be sure to say hello to Aaron Williams, and attend his presentation on Wednesday at 3:15pm.
