GE has developed an electrically powered marine propulsion system that, it believes, could result in fuel savings of up to 10% compared to conventional azimuth propulsion systems, as well as lower emissions. It says the development “could change the way the maritime industry views propulsion technology”.
Turck claims to have developed the first high-resolution, non-contact universal encoder that is immune from magnetic fields and free from wear. The encoder has separate inductive sensor and positioning elements that are are encapsulated (to IP69K) and work together without making contact.
Balluff believes that it will revolutionise the light tower market with the first system that can be adapted freely to almost any requirement without complex hardware reconfiguration. The software-configurable Smart Light, which can include up to 20 360-degree LEDs arranged vertically, can do much more than simply signal predefined operating states using three colours.
Keyence claims to have made a breakthrough in profile measuring technologies with a system that it says is about 30 times faster than its closest rival. The LJ-V system can measure 12.8 million points (or 64,000 profiles) in a second, and can scan targets moving at speeds of up to 6.4m/s in 0.1mm steps.
Schaeffler has joined forces with Ford to build an experimental electric version of the Ford Fiesta that is driven by two 40kW motors built into the rear wheels. The liquid-cooled wheel-hub drives also contain all of the components needed for motor control, braking and safety, including the power electronics.
ABB has developed “the first low-voltage circuit breaker with integrated energy management functions”. It claims that the Emax 2 breaker can reduce power consumption by up to 15% if used instead of traditional breakers. It is designed to be used where large amounts of energy are being controlled and protected in a LV environment, such as in industrial and commercial buildings, and data centres.
The US robotics specialist Adept Technology has developed a self-navigating “autonomous indoor vehicle” (AIV), designed to move materials from point to point in challenging environments such as confined passages and populated areas.
Phoenix Contact’s automation software subsidiary, KW-Software, has developed a way of running Profinet IRT (isochronous real-time) on a standard Intel Ethernet controller. Until now, custom chips have been needed to provide sufficient precision.
SKF has developed a high-speed motor running on magnetic bearings that, it claims, can cut the energy consumed by aeration blowers in wastewater plants by up to 40%. The potential savings are substantial because aeration blowers can account for up to 80% of a wastewater plant’s total energy consumption.
The world’s biggest compressor manufacturer, Atlas Copco, has entered the electric motor design and manufacturing business by developing an oil-cooled permanent magnet motor for a new generation of variable-speed drive compressors that, it says, will halve energy use compared to idling compressors.
At the recent Hannover Fair, Lenze unveiled an integrated motor and controller that can be programmed and operated wirelessly from a smartphone. The Smart Motor will run at speeds from 500–2,600 rpm while maintaining constant torque, thus reducing the number of drive variants that users will need to stock by around 70%, according to Lenze.
Schaeffler’s direct-drive division, INA Drives & Mechatronics (Idam), has developed a technique for producing ironless linear motors in which the motor’s coils are “printed” layer by layer. The pioneering technique will allow the motors to be manufactured in volume at lower costs than before.
The Swiss logistics equipment specialist Interroll has announced a magnetically-based speed controller for pallets that, it says, “takes safe pallet-handling operations to a new level”. The company has spent three years developing the wear-free technology that works without uising friction pads
TE Connectivity has developed a technology that transmits power, signals and data in almost any environment without needing physical connectors or contacts. The Ariso system integrates wireless power and radio frequency (RF) technologies and is said to combine the reliability of contact-based connections with the flexibility of contact-free connections.
GE Intelligent Platforms has announced the first in a series of apps for mobile devices designed to deliver “real-time operational intelligence” (RtOI), and allowing users to transform data into “actionable knowledge”. The app, called Proficy Mobile, provides real-time access to operational data via Apple iOS or Android devices, and an interface with GE’s GEO-intelligence technology which provides intelligent information based on the user’s location, role and asset location.
