Maxon has published a handbook about DC drive system selection. “The book includes a six-step flowchart, providing a clear path to select the drive system specific to application requirement,” said the company. “The chapters dedicated to each drive system component also offer the formulae required to select the right product at each stage. Illustrations and descriptions of the variables bring ...

Nanotec has introduced a series of frame-less brush-less dc motors – essentially a stator-plus-rotor kit intended to be installed directly into a physical structure that will provide support, alignment and bearings. “By eliminating the need for couplings or additional mounting components, these frame-less motors reduce material usage and assembly costs,” claimed the company. “The design also simplifies cable management and ...

EPC is specifically aiming at designers of humanoid robots with its EPC91104 7A 48V brushless dc motor driver evaluation board, built around GaN power transistors. Measuring 72 x 75mm and operating across 14 to 80V with peaks up to 20A, it implements only the power stage, needing a separate signal generator board to work, as well as heatsinking. The company ...

Toshiba is aiming vehicle body automation with it its latest three-phase motor diver. TB9084FTG, as it will be known “supports replacing brushed dc motors with quieter, longer-lasting BLDC motors to drive body system applications like powered sliding passenger doors, power tailgates, adjustable seats, electric pumps and fans”, it said. The IC is designed to control the gates of seven external ...

From rotating magnets, Melexis is intending to generate two quadrature outputs with “minimal jitter as well as consistent 90° phase shift regardless of magnet pole pitch” from single IC containing two magnetic Hall sensors. The aim is to replace pairs of accurately-spaced single Hall sensor ICs with a single new IC, called MLX92253, that uses precision angles to replace precision ...

Toshiba is aiming at air conditioners, air purifiers and pumps with an IGBT-based brush-less dc motor driver, suitable for sine-wave generation, in a ~13 x 33mm through-hole HDIP30 package. TPD4165K, as it will be know, can handle a maximum output of 3A, compared with 2A for the company’s earlier TPD4163K or TPD4164K. Absolute maximum input voltage has been raised to ...

Teknic has added an EtherCAT interface to some of its brushless servo motor models, creating the ClearPath-EC range. These come in frame sizes from NEMA 23 to 34 and powers from 38 to 429W, and the motors are sealed to IP66K or IP67 which enables them to be washed down. All feature an internal position encoder, and are programmable via ...

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, ...

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 ...

EPC is aiming at eMobility, forklifts and high-power drones with a 150Arms brushless motor driver design using its GaN power transistors. Documents for EPC9186, as it will be known, are not available yet, but the company promises operation from 14V to 80V for “applications such as electric scooters, small electric vehicles and agricultural machinery” in addition to the items above. ...
