Today’s boat engines, gallon for gallon, emit more pollutants than vehicles on the road. As a result, the US Environmental Protection Agency introduced requirements for catalytic converters on inboard and stern-drive boats beginning in 2011. Many manufactures of personal watercraft initially switched to outboard propulsion and are now looking to electric motors as the next step.

Converting a boat from gasoline to electric is not as straightforward as dropping in a battery and motor from a car, though. Since boat drag increases with speed, the energy to move a boat through water is far greater than that required for an equivalent electric vehicle.

Arnold offers Arnon silicon steel, laminated magnets and carbon-fiber windings for electric motors that require higher efficiencies. Arnold’s non-grain oriented electrical steel (NGOES) is optimized by thickness and finish. Arnon silicon steel is frequently used for laminations in high speed, high-efficiency motors and generators. Whereas common laminations use thicknesses between 0.356mm and 0.813mm, Arnon 5 and Arnon 7 are thinner – at 0.127mm and 0.178mm respectively.

Arnon electrical steel has been shown to be particularly advantageous for higher-frequency motors and generators above 400Hz. In these designs, the thinner material offsets the less efficient effects of increased eddy currents and subsequent heat build-up. Using thin laminations of Arnon produces a more efficient unit and frees up design constraints by making it possible to fully enclose the motor without external cooling, for example.

Arnold’s Wraptite composite sleeves offer a superior design alternative to metallic solutions, particularly in applications that require high rotational speed or the containment of high centrifugal forces – such as high-speed motors and generators. Wraptite has a low density and high strength-to-weight ratio, as well as greater containment stresses for sleeves of the same thickness, leading to increased rotor speeds. Reduction or elimination of eddy currents in the containment sleeves reduces hear generation and improves efficiency.

Wraptite composite materials include carbon fiber, Zylon fiber and glass fiber composites using a range of epoxy cyanate ester and BMI-based (bismaleimide) resin systems. The material can operate at temperatures up to 170° C.

When entering a partnership, the first step is to decide what the end goal is, and how best to accomplish it. Perhaps a world-class supplier is struggling with pricing, quality or delivery from its existing supply chain. In that case, Arnold can be an alternative source for either an individual motor component or the complete motor system, having complete control over the supply chain. For example, Arnold sources SmCo (samarium cobalt) magnets from its plant in Switzerland, where all pressing and sintering is done in-house, coupled with a partnership with a rare earth mine to ensure the supply of quality raw materials.

Developing a marine electric motor takes specialized expertise in electric motor design. Arnold can collaborate at whatever step of the process makes the most sense. It offers everything from specialist information on permanent magnet technology, to sources components from an extensive selection of Arnold-operated global resources, all the way up to a complete motor design. Arnold provides quick-turn design, rapid prototyping and testing, using one of its technology centers around the world.

Marietta, OH: Magnetic and magnetic-receptive materials are well suited for display and point of purchase applications like menus and promotional signs, anything where messaging may change on a daily, weekly, or monthly basis. The ease of change out is appealing especially to retail workers with little to no experience handling signage.

Magnets come in various thicknesses. Over the years, “thin” materials have become popular. For the purposes of this article, we define thin magnetic material as anything around 7- to 17-mil or 0.007 to 0.017 inches thick.

What’s the Buzz?

Thin magnetic material is developed and used by a number of different industries. For printing, one of the reasons “thin is in” is because it runs better on printer hardware compared to its thicker gauge counterparts.

According to Stephen McLevey, business development and Flexmag commercial manager, Arnold Magnetic Technologies, the print industry is driving demand. “The material needs to be thinner and lighter so that it can be processed on the printers used in today’s marketplace.”

Debunking Myths

A common misconception is that the thicker the magnet, the more powerful the attraction. Weary of using thinner magnetic material because of this? You shouldn’t be.

“The statement is true as long as the material is of the same grade. We are able to produce a stronger, thinner magnet by using higher energy materials,” says McLevey.

Thin Benefits

Advantages of thin magnetic materials center around weight. This makes it easier to load the media into printer. Another point to consider, lighter weight options reduce shipping costs.

Thinner magnets also conform better to curved and uneven surfaces compared to thicker options, suggests McLevey. This makes thinner gauge magnets useful for vehicle graphics.

Final Thoughts

Thinner gauge magnets are not your traditional materials. Lighter weight magnetic and magnetic receptive substrates with equal – if not more – energy are designed for today’s printers.

The post Less Weight, More Energy with Flexible Magnets appeared first on Arnold Magnetic Technologies.

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.

Rochester, NY | Kingston, Ontario: Arnold Magnetic Technologies Corporation (“Arnold”), a subsidiary of Compass Diversified (NYSE: CODI) and leading global manufacturer of high-performance magnets and more for mission critical applications, announces its partnership with Cyclic Materials, a pioneer in developing more sustainable domestic supply chains for rare earth elements. Arnold and Cyclic will work together to develop a rare earth recycling program, creating an unprecedented circular supply chain for rare earth materials.

Arnold produces permanent magnets made from rare earth materials. Cyclic Materials’ recycling capabilities allow for the reuse of rare earth materials reclaimed from magnets. While previous recycling measures only reclaim select elements, Cyclic Materials plans to recycle all elements from Arnold’s supply feed to offer a broader range of recycled materials at a much higher yield. This will allow Arnold to source recycled, rare earth Samarium, Neodymium, and Dysprosium, along with non-rare earth cobalt from Cyclic Materials moving forward, creating a North American supply source. Arnold is exploring options for expanding this partnership to the rest of their North American locations.

Rare earth magnets are used in a myriad of applications across all markets, including electric motor applications. For this application, rare earth magnets are especially sought after due to their power-dense material characteristics and relatively lightweight composition. These unique characteristics can be utilized to greatly increase the power density of electric motors. By utilizing recycled rare earth materials in its future magnets, Arnold will be able to increase the sustainable impact of electric motors and other products.

Currently, rare earth supply chains are extremely dependent upon China. Arnold and Cyclic Materials will be able to reduce dependence upon foreign nations for these materials by increasing supply chain efficiency with value-added recycling. This reduces waste both up and downstream and greatly reduces environmental impact as a result. With this partnership, Arnold will need fewer virgin materials and will increase the resiliency of their supply chain—offering more capacity and more flexibility for production.
