Two-motor powertrain ‘can raise EV efficiencies by 15%’

25 July, 2013

An Italian vehicle transmission specialist, Oerlikon Graziano, and a UK controls specialist, Vocis Driveline, have jointly developed an electric vehicle transmission system that uses two traction motors in a compact powertrain that provides four speeds and operates with an efficiency of around 90%.


Project aims to develop lightweight motors using plastics

23 July, 2013

German researchers have embarked on a three-year collaborative project aimed at improving the power-to-weight ratios of electric motors by incorporating lightweight materials such as fibre-reinforced plastics.


Integrating electronics with motors could halve power-to-weight ratios

18 July, 2013

The German government is providing €10m of funding for a collaborative project aimed at integrating electronics into electric motors, thus improving power-to-weight ratios by up to 50% and cutting system costs by up to 40%, compared to using separate sub-systems.


Tiny current sensors could lead to smaller, more efficient VSDs

15 July, 2013

Japanese developers have produced a tiny, precision current sensor that, they predict, could lead to lighter, smaller, more efficient inverters. The GCBC sensor uses a proprietary magnetic sensing element that eliminates the need for a core to concentrate magnetic flux, resulting in a board-mounting device that weighs just 3g.


EtherCat semiconductor profile ‘could lead to dramatic developments’

10 July, 2013

The EtherCat Technology Group (ETG) has released a new profile for semiconductor manufacturing applications which, it says, provides a starting point for a new generation of tools and could lead to dramatic developments in the industry.


Single-tooth motors could bite into the EV market

09 July, 2013

German researchers are developing a new generation of high-efficiency motors for electric vehicles (EVs) with the aim of challenging two perceived limitations of EVs – their limited ranges and high purchase prices.


$34m contract will take electromagnetic railgun closer to firing

09 July, 2013

The US Office of Naval Research (ONR) has awarded BAE Systems a $34.5m contract to take development of an electromagnetic railgun to the next stage. These long-range “guns”, which work on the same principle as a linear motor, using electromagnetic energy instead of explosive chemical propellants, could launch a projectile farther and faster than any previous gun.


FF aims to make digital buses easier to use than analogue

04 July, 2013

The Fieldbus Foundation has announced a technology development initiative, called Project Gemstone, intended to make digital fieldbus automation easier to use than analogue control systems in every way, from device setup to device replacement and daily maintenance practices.


Power storage modules support DC buses in servo systems

27 June, 2013

Kollmorgen has developed a range of power storage modules incorporating a novel capacitor technology designed to improve the performance of servo motion systems by re-using braking energy and bridging short power outages safely.


Rare earths are recycled from batteries to motors

25 June, 2013

Three Japanese companies – Honda, TDK and Japan Metals & Chemicals – are working together on a scheme to recycle rare-earth metals extracted from batteries to produce magnets for new electric vehicle motors.


Platform is ‘first to manage big industrial data in the cloud’

25 June, 2013

General Electric claims to be offering “the first big data and analytics platform robust enough to manage the data produced by large-scale, industrial machines in the cloud”. It says that the platform, built to support the Industrial Internet and turn big data into real-time insights, will benefit industries such as energy production, transportation and manufacturing.


Carbon fibre rope heralds the 1km elevator ride

25 June, 2013

The Finnish elevator manufacturer Kone has developed a lightweight carbon-fibre-based lifting rope that will allow elevators to travel through heights of up to 1km – twice as far as is possible at present. The UltraRope hoisting technology will also result in energy savings of up to 45%.


Novel insulation allows motors to operate twice as long at full power

25 June, 2013

Japanese researchers have developed a new insulating material for motor coils that allows a motor to operate at maximum power for more than twice as long as conventional insulation. The new material also improves the motor’s efficiency by about 1%.


Software bridge links robots and machine tools

25 June, 2013

Researchers in the US have demonstrated an open-source software technology that collects and communicates real-time information from manufacturing processes and factory-floor equipment supplied by a variety of vendors.


Integrating EV motor with charger saves time and cuts costs

25 June, 2013

Swedish researchers have integrated an electric vehicle’s motor and inverter with its battery-charging circuit in a way that reduces charging times from eight to two hours, and cuts the EV cost by around $2,000.
