ROHM's New Three-Phase BLDC Gate Driver Uses TriC3 to Cut Switching Loss for Medium-Voltage Motors ROHM’s new three-phase brushless DC motor gate driver uses its proprietary TriC3™ technology to minimise FET switching loss without compromising on electromagnetic interference (EMI). It is designed for motors that run on 12 to 48V power sources, meaning that applications include electric drills, industrial fans, air conditioners, and E-bikes. The TriC3™ tech helps mitigate the usual… |

3D-Printed Hovercraft Glides Over Land and Water A maker has designed an impressive DIY hovercraft that can glide over water, grass, and hard surfaces using a powerful air-cushion system. The body is made from four modular parts, 3D printed to fit standard printer sizes, with strong mounting points and precision bearings for smooth mechanical movement. The hovercraft uses two motors, one for lift and one for forward thrust. A 5-inch… |

DIY Robotic Arm with Brushless DC Motors and Raspberry Pi JesseDarr’s new project is different from the usual DIY robotics project. He has made a robotic arm called dARM. It is a robotic arm with 6 degrees of freedom, and most of the parts are 3D printed. He has used brushless DC motors for its working rather than servo motors. These are the kind of motors you would usually find in more advanced machines, and they help the arm move more smoothly and… |

Brushed or Brushless DC Motor? The broad world of DC motors has two basic categories: brushed and brushless. The brushed motor has been around since the 1830s (yes, that long!), and billions of them have been used successfully. However, the brushed motor also has many well-known drawbacks, including brush wear, electrical noise, and controllability issues. Despite these shortcomings,… |
