Volatility in the Rare-Earth Material Markets – Some Benefits After All

Guest Column by Magnet Applications

Since the final quarter of 2010, there have been some extraordinary movements in the prices of rare-earth metals and the precursors for their manufacture. This has been caused by a number of factors, including the effect of export quotas, the need to clean up certain parts of the production chain, speculators and the desire to put pressure on companies to develop non-Chinese sources. Added to this, the actions of lobbying groups who really would like to make everyone think that the Chinese would actually cut off supply, causing governments to consider financial handouts, and it is no surprise that there has been upward pressure on prices.

Allegro MicroSystems, Inc. Introduces a New Customer Programmable Linear Hall-Effect Sensor IC
allegroAllegro MicroSystems, Inc. has introduced a new linear Hall-effect sensor IC with a wide ambient temperature range of 40°C to 150°C. Allegro’s A1357 device is a high precision, customer programmable, Hall-effect linear IC with a pulse width modulated (PWM), current sourced (2-wire) output. The duty cycle (DC) of the PWM output signal (freq: 1 kHz) is proportional to an applied magnetic field. The device converts an analog signal from its internal Hall sensor element to a digitally encoded PWM output signal. The coupled noise immunity of the digitally encoded PWM output is improved compared to the noise immunity of an analog output signal.

 

The BiCMOS, monolithic circuit inside of the A1357 integrates a Hall element, precision temperature-compensating circuitry to reduce the intrinsic sensitivity and offset drift of the Hall element, a small-signal high-gain amplifier, proprietary dynamic offset cancellation circuits, and PWM conversion circuitry. The dynamic offset cancellation circuits reduce the residual offset voltage of the Hall element. Hall element offset is normally caused by device over molding, temperature dependencies, and thermal stress. The high-frequency offset cancellation (chopping) clock allows for a greater sampling rate, which increases the accuracy of the output signal and results in faster signal processing capability.

 

The A1357 sensor IC is targeted at the automotive and industrial markets and is provided in a lead (Pb) free, 3-pin, single inline package (KB suffix), with 100 percent matte tin leadframe plating.  It is priced at $1.50 in quantities of 1,000.


beiBEI Kimco Magnetics Introduces Limited Angle Torque Motor Featuring Zero Cogging for Smooth Operation
Precision positioning and actuation applications require exceptionally smooth motor operation without disruption from cogging. To meet these highly specialized demands, BEI Kimco Magnetics has introduced the new BLDC Limited Angle Torque Motor Model LAT40-48. The LAT40-48 Motor meets market demand for a zero cogging motor with high peak force in a small form factor package.

 

The LAT40-48 motor is a limited angle torque motor. The rotor of this motor has no preferred position. These design elements combine to provide a motor that completely eliminates cogging. The result is consistent, extremely smooth performance critical to applications that depend on uninterrupted operation, such as stabilization platforms, scanning and beam steering.

 

"The beauty of this limited angle torquer is that it has absolutely zero cogging or detent which makes it ideal for stabilization applications," said Jim McNamara, BEI Kimco's Senior Applications Engineer. "To have that kind of torque without cogging is quite unique to the market."

 

The new motor also features a single phase winding that provides easy control, a 30° excursion is accomplished with no commutation. Use of rare earth, high energy magnets creates a power density of 10.08 oz-in watt.   Other important performance characteristics include ±15° stroke, a peak torque of 21.5 Nm, and single phase winding. These high level functions are all packed in a compact 100.0 mm diameter by 100.0 mm stack length size. 

 

As a Brushless DC Motors (BLDC) with fixed magnets, the LAT40-48 offers all the inherent advantages over brushed DC motors, including more torque per weight, more torque per watt (increased efficiency), increased reliability, reduced noise, longer lifetime (no brush and commutator erosion) and overall reduction of electromagnetic interference.

 

"While many companies make full rotation motors and even custom full rotation motors, not many companies offer custom limited angle torque motors," said McNamara. "When you can't find what you're looking for in an off-the-shelf product, BEI can provide the solution - we use state of the art materials and design processes to provide custom products to meet extreme requirements."

Molycorp Secures 78 Percent of Phase 1 Rare Earth Production in Customer Agreements and XSORBX Production
Molycorp, Inc. has announced that 78 percent of its Phase 1 rare earth production from its new Mountain Pass, Calif. manufacturing facility, which comes online in 2012, has now been secured by signed customer agreements or has been committed to production of the Company's XSORBX water treatment products.

The company said it has entered into written agreements with customers covering 58 percent of its Phase I production, and has allocated an additional 20 percent to production of XSORBX, for a total of 78 percent of the 19,050 metric tons of rare earth oxide (REO) equivalent that it intends to produce annually under Phase 1 at its flagship Mountain Pass, Calif. rare earth facility.  Exact terms, prices, duration, and products covered by these agreements vary from customer to customer.  Another six percent of Phase 1 production is in final stage discussions with customers, the company added.

 

Molycorp intends to sell its proprietary, cerium-based XSORBX water treatment products across four market segments: municipal water treatment, recreational/pool/spa water, industrial wastewater and drinking water purification.  The company currently is selling XSORBX to commercial customers in the municipal wastewater treatment and recreational/pool/spa markets.

 

“I am very pleased that we have met the Phase 1 off-take allocation target that we set for 2011, and have found a home for more than three-quarters of our Phase 1 production prior to start-up,” said Mark A. Smith, Molycorp’s president and CEO. “In an industry that traditionally has been driven by spot sales, Molycorp continues to break ground by moving customers to stable, secure, long-term supply contracts."

 

"Securing long-term rare earth sales contracts requires the ability to produce and deliver actual product to customers for extensive testing, qualification, and fine tuning so that precise specifications can be met,” said Smith.  “This process can take many weeks, even months, to complete. I am very pleased with our progress to date in working with our customers to ensure we can serve as a reliable, long-term supplier of these strategic materials."


Is Automotive a Promising Market for Rare Earth Elements?
Rare Earth Elements (REEs) such as neodymium are widely used in commercial electronic products and a wide range of other industries. The automotive industry, a vast consumer of raw materials, is a big potential market for REEs, not least because of the move toward hybrid and electric vehicles (EVs) which require higher volumes of REEs. However, uncertainty currently exists over the future demand for EVs and the use of REEs.

 

IMS Research estimates that 16 million EVs will be produced in 2021, of which nearly 60 percent will be hybrid electric vehicles. This augers well for the mining industry: after all, several kilos of expensive REEs are required per vehicle. However, Alastair Hayfield, Automotive Research Director, cautions against over-optimism, “The long term forecast for EV production is subject to uncertainty as a lot rests upon governments and private enterprises incentivizing and driving EV adoption.” Hayfield continues, “It should also be noted that vehicle manufacturers are exploring technologies that don’t rely as extensively on REEs. Not only do vehicle manufacturers want to lessen their exposure to price fluctuations, they want to reduce their reliance on materials that are hard to source. Couple this with emerging REE recycling programs that are targeting ‘urban mines’ (REEs sequestered in consumer electronic devices, for example), and the REE mining industry might not achieve the level of mid-term success it hopes for from the automotive industry.”

 

Despite this more pessimistic viewpoint, companies would be wise not to overlook the opportunity presented by automotive body and control motors used in internal combustion engine vehicles. IMS Research estimates that an average of 25 electrical motors were used per light vehicle in 2011, equating to annual global shipments of 2 billion units. By 2018, annual global shipments of electrical motors are forecast to rise to 3.5 billion, a 75 percent increase. This presents a healthy opportunity for motor suppliers, magnetic material suppliers and REE mining firms.

 

There are three main factors driving this trend: the first is rising sales of light vehicles, most notably in emerging economies. Second, more convenience and comfort systems that require motors, such as HVAC or electric windows, are being used on lower segment cars. Third, in a bid to differentiate and offer a ‘better’ driving experience, vehicle manufacturers are offering ‘premium’ features that physically manipulate the driving environment, such as multi-zone HVAC or tailgate lift, on a wider variety of vehicles.

 

In the long term, the automotive industry will continue to be a major consumer of REEs, particularly as the use of motors increases. However, if REEs continue to be a ‘pain point’ for automotive suppliers, either through high price or scarcity, then an attempt to reduce their consumption should be expected.


Advanced Magnet Lab Awarded US Department of Energy Grant to Develop Next Generation Wind Turbines
Magnet Lab, Inc. (AML) is among six awardees of a grant from the US Department of Energy (DOE) for the advancement of next generation wind turbine technology. AML was selected based on a proprietary innovative turbine generator which enables the development of the first fully superconducting direct-drive generator for large offshore wind turbines. These generators are up to 75 percent lighter, 50 percent smaller, more efficient and more reliable than systems in use today. This award represents an initial step in the fulfillment of AML’s Clean Energy Plan for deployment of clean, scalable and efficient generators and motors for large-scale energy systems. Successful development and deployment of this new technology will help position the US as a global leader in wind energy technologies, reduce the cost of wind energy, and support thousands of new manufacturing, construction and planning jobs in the renewable energy market.

 

Energy prices and environmental concerns are driving the US to develop domestic sources of clean, renewable energy. Research indicates our nation possesses abundant resources to create electricity from wind; and the DOE believes that generating up to 20 percent of the nation's electricity supply from wind power by 2030 is an achievable goal. Much of that production would come from offshore wind farms, as offshore wind is significantly steadier and nearer to where the majority of the population resides, reducing the cost and energy losses of power transmission. Over 160,000 Megawatts (MW) of offshore wind energy projects are scheduled to be installed during the next decade throughout the globe.

 

Vernon Prince, general manager of AML Clean Energy said, “Wind turbines generating 10-MW of electricity power will serve over 4,000 homes and will lead to more economical and efficient wind farms. Scaling up to these mega-turbines presents many challenges including high reliability and economic viability. Conventional technology simply cannot achieve that scale. AML’s solution is transformational by reducing the size and weight of the drive train using superconductors and a very robust generator architecture.”

 

The funding will support the design and preparation of AML’s energy analysis model for its fully superconducting 10-MW generator. Collaborators on the project include a large US industrial manufacturer and Argonne National Laboratory. "Direct-drive generators eliminate the need for a gearbox, which reduces weight, eliminates moving parts and reduces maintenance costs," said Jerry Nolen, an Argonne Distinguished Fellow. "Turbines based on superconducting technology will have a huge impact on how future electricity is generated by reducing costs and increasing reliability and efficiency."

 

AML’s solution is based on the principle of superconductivity, which allows the flow of electrical current with zero electric resistance and without energy losses when operating in a very low-temperature environment. “When applied to high power applications, superconductivity has the potential to provide revolutionary changes in power generation, power transmission and energy use by significantly reducing the cost of energy  production and increasing energy efficiency in ways that are environmentally benign,” according to Dr. Philippe J. Masson, a Senior Scientist at AML and Principal Investigator for the DOE grant.
