TDK has announced automotive smart motor drivers that can handle 4 x 1A peak current and include an Arm Cortex-M3 processor core. HVC 5222D with 32kbyte of flash and HVC 5422D with 64kbyte can drive brushless dc, brushed dc (2A) and stepper motors. They also have 4kbyte ram, 2kbyte of emulated eeprom and 1kbyte of non-volatile registers, and are “SEooC ...

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 ...

AMD has introduced a motor driver starter kit for its Kria K24 system-on-module – which is built around a Zynq UltraScale+ IC and measures 60 x 42 x 11mm. The kit, called KD240 drives starter kit, includes the module, a carrier card and a heat sink. Included is 2Gbyte (2chan x 256Mbit x 16bit/chan) of LPDDR4, and a 512Mbit QSPI ...

Toshiba is aiming at pumps, air conditioning and fans with through-hole versions of its latest 600V three-phase brushless dc motor drivers. TPD4163K and TPD4164K come in a 32.8 x 13.5 x 3.525mm ‘HDIP30′ package, which has pins on a 1.778mm pitch (Electronics Weekly has asked why this odd pitch was chosen – watch this space). “This new package reduces PCB ...

TDK is aiming at motor testing with the introduction of a power sinking option to 1.7 and 3.4kW models of its Genesys+ 1U-high rack-mount dc power supplies – it is only available for 0-20, 0-30, 0-40, 0-60 or 0-100V output versions. Mounted internally, the sink module (photo below) can absorb 100W continuously and 300W of peak, and fall time can ...

Transistor maker GaN Systems has signed a memorandum of understanding with QPT, a start-up with patents covering power modules  designed using RF techniques to get the best out GaN transistors. The MOU covers the use of QPT technology and GaN Systems transistors in electric vehicle power converters – in particular: 100kHz to 20MHz hard-switching high-power and high-voltage converters. “We are ...

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 ...

Delo has created a high-temperature adhesive for electric motor components. “HT2990 is designed for use in multiple processes, including magnet bonding and magnet stacking in electric motor manufacturing,” according to the company. This is a dual-cure adhesive: Heat is the main way that it is cured, but accessible parts of its can also be cured in 10s using light (400nm ...

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 ...
