The simple circuit was designed using a 555 timer and pulse width modulation for controlling the speed of DC motor. The pulse width modulation (PWM) pertains to the process of switching the power ...

We’ll be honest right up front: there’s nothing new in [David Cambridge]’s brushless motor and controller build. If you’re looking for earth-shattering innovation, you’d best look elsewhere. But if ...

Texas Instruments announced the expansion of its motor driver portfolio with the addition of 12-V motor driver family that reduces spin-up time to just seconds and makes tuning stepper and brushed DC ...

Getting step motors up to speed has never been a problem. Getting them to stop is a different matter. Step motors (because of their magnetodynamics) are naturally springy, so they tend to vibrate at ...

REDSTONE ARSENAL, Ala. -- A team at the U.S. Army Research, Development and Engineering Center, Aviation and Missile, has recently worked to develop a new dual pulse rocket motor. The Weapons ...
