Roskill forecasts demand for neodymium for magnets to result in supply deficit; substitutions by 2021
November 08, 2016
In its new rare earths market report with forecasts out to 2026, Roskill, a leader in international metals and minerals research, observes that the permanent magnet and catalyst sectors will continue to provide the largest markets for rare earths in the next ten years to 2026. Catalysts will continue to drive growth in the light rare earth elements lanthanum and cerium, while permanent magnets will lead growth in neodymium, praseodymium and dysprosium.
However, Roskill also projects that, driven by rapidly increasing demand for neodymium-iron-boron (NdFeB) magnets (used in traction motors among other applications), neodymium will fall into deficit in 2016, although demand will initially be met by the drawdown of stocks. Roskill forecasts that the deficit will increase to 2021, making continued growth of NdFeB magnets unsustainable, despite efforts by rare earth producers to increase neodymium supply.
Nissan introduces series-hybrid powertrain with Note e-POWER in Japan; small pack, small engine, LEAF motor, low price
November 02, 2016
In Japan, Nissan Motor introduced its new series-hybrid drive system called e-POWER along with its application in the Note. This marks the first availability of e-POWER technology for consumers, marking a milestone in the electrification strategy under Nissan Intelligent Mobility.
e-POWER borrows from the EV technology in the Nissan LEAF. Unlike the all-battery-electric powertrain of the LEAF, e-POWER adds a small gasoline engine to charge the high-output battery when necessary, eliminating the need for an external charger while offering the same high-output. Nissan says that although e-POWER uses a much smaller battery than the LEAF (1.5 kWh vs 30 kWh), it delivers the same driving experience as a full EV.
ORNL team shows 3D-printed permanent magnets outperform conventional versions, conserve rare materials
Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) and colleagues have demonstrated that permanent magnets produced by additive manufacturing can outperform bonded magnets made using traditional techniques while conserving critical materials. NdFeB magnets are used in a range of applications from computer hard drives and headphones to clean energy technologies such as electric vehicles and wind turbines.
The team fabricated isotropic, near-net-shape, neodymium-iron-boron (NdFeB) bonded magnets at DOE’s Manufacturing Demonstration Facility at ORNL using the Big Area Additive Manufacturing (BAAM) machine. The result, published in an open-access paper in Scientific Reports, was a product with comparable or better magnetic, mechanical, and microstructural properties than bonded magnets made using traditional injection molding with the same composition.

Tsinghua team evaluates impact of types and arrangements of electric traction motors in fuel cell hybrid buses
April 20, 2016
Researchers at Tsinghua University have compared the performance of two different powertrains for fuel cell hybrid buses. Both buses use 50 kW PEM fuel cell stacks (from different manufacturers) as the primary power source, with LiMn2O4 battery packs as secondary power sources. A significant difference between the two powertrains lies in the types and arrangements of the electrical motor.
One powertrain employs a single induction motor (IM) to drive the vehicle via a reduction gearbox and differential (Powertrain A), while the other powertrain adopts two permanent magnetic synchronous motors (PMSMs) for near-wheel propulsion (Powertrain B). A further difference between the proposed powertrains is the supply path for the fuel cell accessories. A paper on their study is published in Journal of Power Sources.

GM details 2016 Chevrolet Malibu Hybrid powertrain design and operation
The 2016 Chevrolet Malibu Hybrid (earlier post) is EPA-rated at 46 mpg (5.11 l/100 km) combined, 47 mpg city and 46 mpg highway; the powertrain shares the transmission architecture with the 2016 Chevrolet Volt extended range electric vehicle (EREV), but includes changes to optimize the system for engine-driven charge-sustaining operation in the range of conditions represented by the US EPA 5 cycle fuel economy tests.
At the 2016 SAE World Congress, GM engineers presented a paper describing the development of the new hybrid powertrain for the popular mid-size sedan. Development was guided by four main objectives:
Saarbrücken engineers developing networked self-analyzing electric motors
March 23, 2016
Engineers from Saarland University are developing intelligent motor systems that function without the need for additional sensors. By essentially transforming the motor itself into a sensor, the team led by Professor Matthias Nienhaus is creating smart motors that can tell whether they are still running smoothly, can communicate and interact with other motors and can be efficiently controlled.
By using data collected from the motor while it is operating, the researchers are able to calculate quantities that in other systems would need to be measured by additional sensors. Further, they are teaching the drive how to make use of this knowledge.
