Brushless-dc motors are taking center stage in medical-equipment design because they last twice as long a competing technologies. • Sensorless brushless-dc-drives have evolved to a point where they ...

A fundamental understanding of the speed-torque curve it the key to specifying a dc motor that will do everything it needs to do. Much has been written about the process of selecting motors for ...

A brushless DC (BLDC) electric motor is likened to a motor with brushes, but turned “inside-out.” A BLDC motor has a rotor with permanent magnets and the stator contains the windings. Older motors ...

There are trade-offs between brushed and brushless motors, considering factors such as maintenance, efficiency and upfront costs, Control Design writes. For automation engineers, the evolving ...

The A3938 is a three-phase, brushless DC motor controller. It has a high-current gate drive capability that allows driving of a wide range of power MOSFETs and can support motor supply voltages to 50 ...

Not satisfied with the specs of off-the-shelf brushless DC motors? Looking to up the difficulty level on your next quadcopter build? Or perhaps you just define “DIY” as rigorously as possible? If any ...

Replacing mechanically driven motors with electrically commutated solutions doesn’t come without specific design considerations. In the automotive sector, the use of electric motors in applications ...

Oriental Motor of Japan has created brush-less dc motors for automated guided vehicles (AGVs) and autonomous mobile robots. BLV-R motors, which are the R type of the BLV series, come in 100W (1/8hp) ...

Maxon introduces HEJ 70-48-50 drive, designed for autonomous mobile robots in unstructured environments. With peak torque of 50 Nm and speeds up to 28 rad/s, it maintains a mass... Maxon's new IDX ...
