Ferrite magnet motors are 3% more efficient than Nema Premium

05 February, 2014

The Californian motor manufacturer NovaTorque has announced 7.5hp (5.6kW) and 10hp (7.45kW) versions of its electronically commutated permanent magnet motors, which it claims are 3% more efficient than Nema Premium induction motors.


PWM servodrives ‘outperform linear drives’

05 February, 2014

The Israeli company ACS Motion Control has developed a range of switching PWM (pulse width modulation) servodrives that, it says, cost less than linear servodrives, but offer better performance, as well as being smaller and more robust. The NanoPWM drives deliver sub-nanometer position jitter performance, and nanometer following errors when moving at low speeds.


Adaptor plugs field devices into wireless networks

05 February, 2014

Yokogawa has announced the first in a series of multi-protocol wireless adaptors that will allow wired field instruments and sensors to be used as ISA 100 wireless devices. The first two models are aimed at wired Hart and RS-485 Modbus devices, and the company is planning to release further models that comply with other wired field communications standards, including Foundation Fieldbus and Profibus.


Micro-PLC can handle small standalone machines

31 January, 2014

Rockwell Automation has announced a micro-PLC for small standalone machines and remote automation projects, such as stretch wrappers and compressors. The 20-point Allen-Bradley Micro820 PLC has embedded Ethernet and serial ports, a micro-SD memory slot, a 5kHz PWM (pulse-width modulation) output, analogue and four thermistor inputs, and recipe management functions.


Magnetic encoders deliver 0.08-degree accuracies

28 January, 2014

Pepperl+Fuchs is claiming a breakthrough in rotary encoder technology with a range of magnetic absolute rotary encoders that deliver accuracies of up to 0.08 degrees with single-turn resolutions of up to 16 bits, and multi-turn resolutions of up to 39 bits. With a sampling time of less than 80µs, they also offer dynamics that “push the boundaries of what has previously been possible,” according to P+F.


EtherCat-based motion controller handles up to 32 axes

28 January, 2014

The UK-based controls manufacturer Trio Motion Technology has announced an EtherCat-based motion controller that can handle up to 32 axes of servo or stepper drives, and 1,024 I/O. The MC4N-ECAT Motion Coordinator supports an expandable library of EtherCat digital drives and I/O modules, and can be mounted alongside compact EtherCat servodrives. A plug-and-play design detects and configures systems automatically.


Digital PC-HMI link stretches to 100m

28 January, 2014

B&R has developed a new version of its Smart Display Link technology that allows HMIs to be located up to 100m away from their PCs. This is the third generation of the technology, which supported PC-HMI separations of up to 40m when it was launched in 2004.


Rack combines eight-axis motion control with an IPC

28 January, 2014

A British company has come up with an all-in-one motion control system which integrates an industrial PC, a touchscreen HMI, an eight-axis motion controller with servo or stepping motor drivers, and a 90–240V power supply, all in 19” rack. MotionLink claims that the Servostep PC is the first integrated system of its type.


Rockwell releases its first machine-mounting controller

24 January, 2014

Rockwell Automation has announced its first machine-mounting safety controller, promising that it will simplify system architectures and save panel space. The Allen-Bradley Armor GuardLogix PAC (programmable automation controller) is a multi-use controller in a hardened package that can be installed directly onto a machine.


Dual-role instrument can test motors and drives

24 January, 2014

New ways of testing motors and drives could emerge following the launch of an instrument that combines power analysis with oscilloscope-style time-based measurement. Its developer, Yokogawa, describes the PX8000 as “the world’s first precision power scope”.


Plug-in modules add extra outputs to power supplies

20 January, 2014

The Japanese automation manufacturer Idec claims to have produced the first industrial power supply that offers a series of optional DC-DC converter modules to provide multiple voltage outputs from a single PSU. The 21mm-wide modules clip onto the side of the PS6R switching power supply to provide a choice of DC voltages, including ±5V, +12V and ±15V.


AC systems drives are based on standardised modules

16 January, 2014

The Finnish drives-maker Vacon has announced a range of AC system drives that will allow systems integrators to offer their customers in heavy industries a variety of standardised drive modules.


Industrial security router protects against cyber-attacks

14 January, 2014

Belden has announced a device that it describes as “the Swiss Army knife of security routers”. The Hirschmann Eagle One router is designed to protect industrial systems against network incidents and cyber-attacks, thus improving security, reliability and performance.


Drive safety monitor can cut machine downtime

08 January, 2014

The German sensor manufacturer Sick has announced a safety device designed to monitor machine movements rather than simply initiating shutdowns, thus reducing unnecessary downtime. The FX3-MOC Drive Monitor – part of Sick’s Flexi Soft modular safety control system – can monitor multiple axes.


Expanded drives family adds new capabilities

07 January, 2014

At the recent SPS IPC Drives show in Germany, ABB announced several extensions to its ACS880 family of industrial drives including: higher power ranges for cabinet-built versions; high-power single-drive module packages; increased protection (IP55) for wall-mounted single drives; and the capability to control synchronous reluctance (SynRM) motors.
