A new multifunctional motor starter from Eaton combines four functions – direct-on-line starting, reversing starting, motor protection and emergency stopping. The EMS electronic starter is said to cut wiring requirements compared to conventional switchgear assemblies by up to 60% and the number of hardware components by up to 70%.
Parker Hannifin has developed a new generation of compact linear actuators with an innovative design using four guide rods to prevent rotation and allow large lateral forces to be applied. The Origa ORD-E actuators can deliver stroke lengths up to 500mm and forces up to 2kN.
The German safety specialist steute has developed a two-channel wireless communications technology designed to be reliabie and to operate effectively in the same area as other wireless systems. The system, called sWave 2.4GHz-safe, is based on a pseudorandom frequency-hopping technology with the hopping pattern known only to the transmitter and receiver.
Residual currents can occur in industrial plants as a result of various problems including: inadequate insulation of terminals or cables; humidity; contamination; or ageing materials. Simple monitoring relays are available that raise and alarm or trigger a shutdown when they detect a rise in residual currents.
The German geared motor and drive systems manufacturer Stöber has expanded its modular drive and automation portfolio with a sixth generation of its drive controllers and motion controllers that use the Codesys v3 programming and controlling software. The two types of controller can be combined to create a drive controller that can be operated in a controller-based mode.
At the recent Hannover Fair, the Brazilian motors and controls manufacturer WEG emphasised the breadth of its low-voltage switchgear portfolio, with several new arrivals including lines of modular contactors and motor protection circuit-breakers.
ABB is continuing to expand its ACS880 family of drives which made their debut in 2011. It unveiled several new developments unveiled at the recent Hannover Fair.
The Californian automation manufacturer Opto 22 has announced a new way to build and deploy simple, scalable operator interfaces based on computers and mobile devices such as smartphones and tablets.
At the recent Hannover Fair, Danfoss unveiled an integrated servodrive based on a permanent-magnet synchronous motor sharing an enclosure with the drive electronics. The VLT ISD 510 drives cover rated torques from 1.7–15Nm and are equipped with Ethernet-based EtherCat and Powerlink communications.
The Austrian automation company Sigmatek has developed a compact modular I/O system that fits up to 20 channels in a 12.5mm-wide module. The rail-mounting S-DIAS modules – which include safety versions – communicate using a real-time Ethernet system called Varan with a bus speed of 100Mbit/s. The I/O modules can be accessed within 1.12µs.
Sick has announced a new generation of safety light curtains that, it says, set new standards for efficiency, ease-of-installation and reliability. The deTec4 Core curtains have no blind zones, offering optimum positioning and protection against unsafe access, while allowing operations to continue efficiently.
SEW-Eurodrive has developed a decentralised frequency inverter for controlling the speeds of asynchronous and synchronous motors without an encoder. The IP55-protected Movitrac LTP-B drive can be wall-mounted, even in difficult ambient conditions.
At the recent Hannover Fair, Bauer Gear Motor launched what it claims is the world's first Ex-rated, IE4 super-premium efficiency geared motor. It adds that the S Series PMSMs (permanent magnet synchronous motors) are the world's most efficient motors for use in explosive atmospheres.
igus has launched a pair of products – anti-microbial cables and plastic energy chains containing easy-to-detect metal particles – designed to help food manufacturers to produce food that is safe for consumption.
