Maxon Motor is launching an electrically commutated motor that the company says promises to push the accepted limits of commercial technology for both efficiency and performance. Maxon designed the EC 25 High Speed motor to produce the highest possible speed for a motor of its size with virtually no vibration - and, in doing so, achieved over 93 per cent efficiency.

"Controlled Power Technologies' breakthrough in the development of a second generation stop-start system, which outperforms existing designs of modified starter motors and alternators in almost every respect, is being demonstrated to engineers and automotive experts this week at Europe's largest conference for vehicle electronics, which is held every two years at Baden-Baden in Germany. The production-ready SpeedStart system is an advanced solution that is more powerful, more efficient and more usable than first generation stop-start systems. It's the first design to integrate all the power and control electronics into a single electric motor assembly and by maximising the number of stop-start events the system aims to significantly reduce fuel consumption and CO2 emissions beyond the NEDC (New European Drive Cycle) measured minimum."

Magnomatics, a Sheffield company which develops advanced magnetic transmission systems and high-torque electrical machines, has signed a six-figure contract with the British Ministry of Defence (MoD), under which it will conduct a detailed design study of a magnetically-geared propulsion motor, based on its patented "pseudo direct drive" (PDD). Under the contract, the company will develop its technology to the megawatt scale, allowing the MoD to assess its potential for use in electric propulsion systems for future frigates and submarines. The project is due to be completed by April 2010, when the MoD will decide whether to devote more funds to taking the technology further. The PDD system integrates magnetic gearing in a brushless permanent magnet machine to provide superior performance in low-speed, high-continuous-torque drive applications. It offers the potential for higher efficiencies in a much smaller package than other motor technologies

"Generator Brushless, 3-phases neodymium magnet generator Brushless Generator: NO motor brushes in our generator and a maintenance-free design with strong neodymium magnets. Old style generators have motor brushes that require regular maintenance. Brushes are high failure items and need replacements regularly."

SiC challenges a $2.6B silicon device market This $2.6B Total Accessible Market is part of the overall $12B Si-based power discretes business (2008). Today the largest applications in potential revenue remain Power Supply PFC, UPS and Motor AC drives. Tomorrow, EV/HEV and inverters for PV installations will take the lead exhibiting higher CAGR (>15%/year). However, cost issues slow-down SiC penetration and we only forecast ~4% of the overall Silicon-based power discretes market to be displaced by SiC in 2019. Low-Voltage applications (< 1.2kV) are representing over 99% of today SiC device sales but we anticipate a huge increase of Medium-Voltage applications (1.2kV-1.7kV) in the next 2 years. High-Voltage apps will slowly appear from 2013-2014 along with technology improvement and cost reduction.

ST40 - is a well-defined radiometric anomaly measuring approximately 1000m by 250m. At the heart of the anomaly, nine sub-crop rock samples were collected within an area measuring 125m by 100m. Seven of the samples produced assays ranging from 2.5% to 5.3% TREO. The seven samples averaged 1.8% Nd2O5 (neodymium oxide) and 417ppm Eu2O3, (europium oxide) which are atypically high amounts for REE projects. The REE distribution of lanthanides for the seven sub-crop samples are: neodymium 46% greater than cerium 20% greater than praseodymium 8% greater than lanthanum 5%. The neodymium levels are highly elevated compared with typical levels of 10% to 15% found in other deposits. The minerals hosting these elements are currently being investigated. Neodymium is one of the more valuable rare earths, as it is a key component in neodymium-iron-boron super magnets used in motors for wind turbines, hybrid cars, and other green technologies. Neodymium oxide currently trades for approximately US$15/kg. Similarly, europium is amongst the least abundant of the rare-earth elements and is a critical component in flat panel display technology. Europium oxide currently trades for around US$500/kg. Two rock samples located 1000m and 1400m west of ST40 (roughly half way between ST40 and ST1) averaged 0.9% TREO. These samples are intriguing because they also contain an average of 1.4% niobium oxide (Nb2O5). This area is predominantly under cover but warrants further exploration to determine potential continuity of mineralization between the two prospects. Niobium oxide currently trades for approximately US$25/kg.
