ABB is focussing on companies exporting heavy equipment to the US with a series of long-life motors built to meet NEMA requirements. Constructed with NEMA 5800 (368.5mm, 14.5inch shaft height) frames, the induction motors can deliver up to 1,750 horse power. They have “high-strength welded steel frame construction usually reserved for larger motors reduces stress and vibration to ensure a ...

Würth Elektronik and STMicroelectronics are demonstrating a brushless dc motor power tool power circuit developed between them. The demo is based on the STDES-PTOOL3A evaluation board. “The Gerber files, bill of materials, schematics and all other reference materials are downloadable from ST.com without charge,” according to Wurth. From ST comes the STM32G4 (Cortex-M4) MCU, STDRIVE101 gate driver and six STL220N6F7 ...

Maria Chizzali is chief operating officer of Italian home automation device provider Sfera Labs. She tells Caroline Hayes how her engineering degree and juggling skills helped her to co-found the company, raise a family and adapt to see the business through the covid pandemic. An early interest in the laws of nature, science and machinery meant that one of young ...

Nexperia has added an 8x8mm package option, and a second 5x6mm option, to its ‘NextPower’ mosfet range which is designed to decrease spiking when switching to reduce EMI. “The Qgate.Rds(on) figure-of-merit has long been a focus for semiconductor manufacturers aiming to improve the efficiency of MOSFET switches,” according to the company. “However, relentlessly pushing this figure ever lower has had ...

Omron is aiming at electric vehicle chargers and solar photovoltaic installations by adding a low contact resistance model to its two-pole single-throw G7L-2A-X series of PCB-mount relays. G7L-2A-X-SI has 10mΩ maximum contact resistance, compared with 100mΩ maximum for existing members of the family. Nominal rating is 30A at 600Vdc, or 25A at 1000Vdc (but see below). Versions with 12V (190mA ...

Stackpole is offering 0.01% 2ppm/°C precision surface-mount resistors in sizes from 0402 to 2512 (1 x 0.5mm to 6.3 x 3.1mm). Part of its RNCF range, these highest spec parts don’t come in the wide value range of lesser RNCF resistors. For example: 0402 types are available between 49.9Ω and 4.99kΩ, then 2512 has the widest span of options,  between ...

Rohm is aiming at motor drives operating on 24, 36 or 48V with n-channel mosfets rated at 40, 60, 100 or 150V to give some leeway for spikes and noise. There are two series with 13 devices all-told: nine in 5x6x1mm HSOP8 (below left) packaging called RS6xxxx, and four in 3x3x0.8mm HSMT8 packaging called RH6xxxx, with current ratings between 25A ...

Recom is aiming at railway use with a family of DIP24 isolated regulated dc-dc converters that will run from between 36 and 160Vdc. Surges up to 200V can be tolerated for 1s. “Dc-dc for rail applications typically operate from 72V, 96V, or 110VDC nominal input with dips and surges,” according to the company. There are 10W (RP10-RAW), 6W (RP06-RAW) and 3W ...

iWave Systems has collaborated with Texas Instruments to create a solderable system-on-module powered by automotive-grade AM62Ax Sitara processors – which are nominally vision processors. Meeting the 45 x 45mm 622pad LGA OSM v1.1 solderable standard, the module is called iW-RainboW-G55M. Courtesy of the TI IC, it has quad 1.4GHz Arm Cortex-A53 CPU cores, an 800MHz Cortex-R5F (MPU channel with FFI), ...

Digital Enhanced Cordless Telecommunications New Radio plus is a new wireless communication protocol that promises to address many limitations of existing methods, filling the gap for reliable, low latency, long range communication, writes Mark Patrick of Mouser Electronics. The advent of the IoT and IIoT (industrial IoT) has brought technology into homes, cars and factories. Most of it depends heavily ...
