New advances in electric motors

New advances in electric motor development could lead to more efficient electric vehicles being developed. Japan’s Tohoku University has been working on switched reluctance motors that feature an axial gap design and do not require permanent magnets. These can deliver the same torque as motors featuring permanent magnets however, a key point as the cost of the rare earths needed in permanent magnets has increased.

New advances in electric motor development could lead to more efficient electric vehicles being developed. Japan’s Tohoku University has been working on switched reluctance motors that feature an axial gap design and do not require permanent magnets. These can deliver the same torque as motors featuring permanent magnets however, a key point as the cost of the rare earths needed in permanent magnets has increased. Meanwhile 2454 Nissan said that sales of its Leaf model are now growing, with 46,000 having been bought. Of these, 25,000 have been sold in Japan, 18,000 in the USA and 7,000 in Europe. Nissan and its partner 2453 Renault plan to sell 1.5 million electric vehicles by 2016 and have established a facility in the US able to produce 350,000 lithium-ion battery packs/year.

In addition, 3055 Mitsubishi is working on plans to increase the number of electric charging points in Japan. Some 400 new 200V charging points will be added, in addition to the 3,192 standard charging stations and 1,380 fast-charging points in the country.

    Honda has developed processes that allow it to recycle the rare-earth minerals from nickel-hydrogen batteries. This is a significant step as the ability to recycle materials from hybrid vehicle batteries will help reduce production costs with the benefit of lowering the overall cost of such vehicles and also address concerns over supplies of the rare-earths. This step will also address some of the criticisms of the environmental factors with regard to hybrid vehicles batteries, due to the previous inability

    The excavator and wheeled loader segments represent massive sales volumes for manufacturers, so new model development is prioritised - Mike Woof writes. The crawler excavator segment accounts for a substantial portion of total sales of construction machines. With this in mind, it is no surprise that this is a market segment for which manufacturers prioritise a significant proportion of their research and development budgets. Wheeled loaders, while not selling in quite such large numbers as crawler excava

    Ever since Henry Ford began mass manufacturing his Model T in 1908, the motor car has grown vastly in importance and has helped transform transportation. However the future availability of fossil fuels as well as concerns over pollution and climate change from CO2 emissions has seen the auto industry look to alternative powertrain solutions. Looking at the powertrain possibilities for the future there are a number of options. Hybrids to a large extent are an interim solution while those for the longer ter
