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. ...

Oriental Motors has introduced sinewave drive vector controllers for its 30 and 50W brushless dc motors, improving speed tracking, reducing audible noise, increasing peak torque (15% for 30W types and 20% for 50W) and adding functions compared with the earlier BLH series of squarewave controllers. The new controllers are called BLH2D (in photo right). “Adopting vector control as the motor ...

Toshiba has introduced a brushless dc motor driver that supports ASIL-D for functional safety in vehicles. Designed in accordance with ISO 26262 (2nd edition) and AEC-Q100-qualified, TB9083FTG is aimed at electric power steering, electric braking and shift-by-wire transmissions. “A built-in fail-safe safety relay pre-driver complements the three-phase pre-driver,” according to the company, and the “SPI communication interface features an integrated ...

EPC9176 is a GaN-based three-phase inverter with a 81 x 75 mm footprint (with connector) that can operate across 20 to 80V and up to 20A (28A peak). “This voltage range and power level makes the solution ideal for a variety of three-phase brushless dc motor drive applications with 36 to 80V input including eBikes, eScooters, power tools, drones, robots, ...

Texas Instruments has introduced 70W brushless dc motor drivers with code-free sensor-less ield-oriented or trapezoidal control. In common, the devices include a set of commutation control algorithms which manage functions such as motor fault detection and protection mechanisms. Operation is from 4.5 to 35V (40V abs max) and the 95mΩ output drivers (high-side plus low-side 25°C) can deliver 8A peak. An adjustable ...

Renesas has announced a pair of three-phase brushless dc motor drivers for cordless battery-powered applications such as power tools, drones, water pumps, vacuums, cleaning robots and fans. They are the system-in-packages RAJ306001 (6-30V) and RAJ306010 (6-42V) which integrate an RL78/G1F microcontroller and a pre-driver into an 8 x 8mm QFN – requiring external mosfets to complete a motor drive. ‘Self-aligned dead-time’ ...
