New TM4 SUMO medium-duty electric motors boost torque and speed 45% with SMCs in place of permanent magnets
June 08, 2016
TM4 will introduce three new SUMO medium-duty (MD) powertrain options at the 29th Electric Vehicle Symposium & Exhibition (EVS29), offering an increase of up to 45% in torque and speed, thanks to a new technological advancement.
Until now, the main rotor technology found in TM4’s electric motors was based on surface-mounted permanent magnets. The desire to limit the use of rare-earth magnets has resulted in a technology choice that leverages the reluctance torque of TM4’s external rotor design (earlier post) and decreases by 25% the use of these elements. By substituting some of the magnets with soft magnetic composites (SMCs), variable reluctance adds up to 45% extra torque and operating speed compared with previous technology in same package dimensions.
European team devises new strategy for rare-earth-free magnets
June 01, 2016
European researchers have devised a new way to make nanoparticles that could replace rare-earth material use in magnets. The researchers used a mixed iron-cobalt oleate complex in a one-step synthetic approach to produce magnetic core-shell nanoparticles.
The resulting materials showed strong magnetic properties and energy-storing capabilities. The approach could signal an efficient new strategy toward replacing rare earths in permanent magnets such as those uses in electric motors and keeping costs stable, the researchers said. A paper on their work is published in the ACS journal Chemistry of Materials.

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.

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.

The engineering team designed the Bolt EV’s electric motor with an offset gear and shaft configuration tailored to meet efficiency and performance targets—most notably more than an estimated 200 miles of range. The motor is capable of producing up to 266 lb-ft (360 N·m) of torque and 200 hp (150 kW) of motoring power. Combined with a 7.05:1 final drive ratio, it helps propel the Bolt EV from 0-60 mph in less than seven seconds.
Tohoku U team produces rare-earth-free high quality Fe-Ni magnet with simple industrial technology
November 22, 2015
Researchers from Tohoku University in Japan have succeeded in producing a completely rare-earth free high-quality Fe-Ni magnet. The team, led by Professor Akihiro Makino as principal investigator is supported by a MEXT (Ministry of Education, Culture, Sports, Science and Technology, Japan) project entitled, “Ultra-low Core Loss Magnetic Material Technology Area,” under the framework of the “Tohoku Innovative Materials Technology Initiatives for Reconstruction.”
Currently high quality magnets, which are used in various applications such as automobiles, household appliances, medical equipment etc. are made up of rare earth elements such as Sm (samarium), Nd (neodymium) and Dy (dysprosium). Importing rare earth elements is costly, and has become “too political,” the researchers said, making it increasingly difficult for Japan to maintain industrial superiority and competitiveness in the production of energy-saving technologies for next generation of electrical machines/devices.
