Maxon has introduced a controller board for brushed DC and brush-less dc motors up to 1,800W (30A) continuous duty and 3,600W (60A) peak, designed for integrating inside products. Operation is across 10 to 60V and -30 to +25 °C (+75°C with derating). Called ESCON2 Module (part 783722), it is a four-quadrant device that can drive and brake in both direction, ...

ABB has created a liquid cooled synchronous reluctance motor series that achieves IEC international efficiency class 5 (IE5). It brands its synchronous reluctance motors ‘SynRM’, and is offering liquid-cooled versions across 37 to 710kW (400V in IEC 200-315 frame sizes (aluminum, steel on request). “A major advantage of the IE5 SynRM liquid-cooled motors is that they are much more efficient ...

RS is stocking five kits of hand soldering and re-work components aimed at different applications, such as micro-soldering and de-soldering larger components. They collect together units selected from Weller’s WXsmart soldering component range. All the kit part numbers are of the form T005345x699, and all of the kits include get Weller’s ‘WXsmart Station’ controller, a soldering iron, a stand for ...

Pickering Electronics had added a single-in-line reed relay which can stand-off 5kV and switch 1.5kV to its Series 104. Inside is a single-pole normally-open contact (‘1 Form A’). Footprint is 6.22 x 24.1mm, and the relays stand 8.1mm tall above the PCB. “This is particularly advantageous where a compact design is essential, as the devices can stack at just 6.35mm,” ...

Looking like a general-purpose problem solver for process control, Teledyne Relays has introduced a seven-function DIN rail mount timing relay that works over 100ms to 100 hours and offers a 5A 240Vac change-over (SPDT) contact, that can handle “small inductive loads” at 2.5A. Operation is over a wide range of ac or dc supplies. There are two versions: MFT02A12 12-240Vdc ...

Panasonic has launched a series of 70A PCB-mount power relays designed to US standards “The HE-R2A relay series is suited for modern wall box designs, and we are happy that we can offer a UL508-compliant sibling of the HE-R type for European four-phase systems, enabling the consolidation of switching functions onto PCBs with space savings,” said Panasonic product manager Bernd ...

CUI has introduced a range of ac fans with air flows 45 and 165CFM Across the 26 member CAF family there are three frame sizes – 120 x 120mm square either 26 or 38mm thick, and or 172mm circular (truncated to 150mm in one dimension) which is 51mm thick. Frames are aluminium, impeller is polymer (PBT, UL94V-0), and there is ...

Toshiba has added over-temperature and over-voltage protection features to an 80V 1.4A photo-relay, all inside a 4pin DIP package. Called TLP241BP, it can switch ac or dc though its single isolate 280mΩ (max) output switch – implemented as a pair of back to back mosfets – and handle pulses up to 4.2A (100ms, 1/10 duty). Output leakage is 1μA max ...

A compact wireless data acquisition system can investigate, monitor and optimise electric rotor motor operation, say Rolf Spellmeyer and Diego Llopis. In modern electric vehicles, different types of electric motors are available. Automobile manufacturers may select asynchronous or synchronous motors, and in some cases, they combine both motor types in one vehicle. In this context, synchronous motors are considered more ...

Broanmain Plastics will be showing recent prototype-to-production projects at the Southern Manufacturing & Electronics exhibition in February. The company offers tool design and various plastic moulding and finishing technologies on a single site in Surrey. One of the projects was a motion sensor housing (right) for Cucumber Lighting Controls, which was seeking a UK-based moulder. “Manufacturing components on UK shores ...
