IAV says new version of modular electric drive can boost range 5-10% vs system with fixed transmission ratio

May 04, 2017

IAV presented a new version of its modular electric drive concept at the Vienna Motor Symposium. Combining a 50 kW (continuous) / 80 kW (maximum) e-motor and transmission, the modular drive unit can support electrification solutions in vehicle classes A to D. The unit represents a further development of a solution IAV presented in 2010. IAV’s aim is to deliver a high level of ride comfort, efficiency and compact packaging at a competitive cost.

Many of today’s electric drives use a combination of an e-motor and transmission with fixed gear ratio. Although solutions of this type are relatively simple in terms of structure, they can be challenged to meet the full range of use cases, IAV says. For example, high hill-climbing performance and maximum efficiency demand very different transmission ratios. To address this, IAV chose a modular concept based on an e-motor and a transmission with one to three speeds.

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.
