You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic ...

Traditionally, DC motors have been used in precise speed control applications because of their ability to provide acceleration and deceleration from a dead stop position to full speed fairly easily.

[Guido] built it with a unique control box, two Arduino 2560’s and an Xbee to ... let you change the color of the sculpture and the speed at which it moves around. Since it’s wireless it ...

On the pll front, one of the things so admirable in the 4046 is phase comparator II – the one I was thinking of exploiting in the motor control. Unlike a multiplier or ex-or gate, phase comparator II ...

FIGURE 1: Variable frequency drives (VFDs) convert a motor’s ac input to dc to a simulated ac signal at varying frequencies. August 31, 2015 Using variable frequency drives (VFDs) to control the speed ...

Seeing as Arduino is good for controlling motors and sensors, Randy added a PING ultrasonic sensor to the front of the vehicle too. So in addition to driving back and forth, the toy car will now ...

To mitigate this problem, some motors and speed controllers have been designed especially to drive a load at low speeds with precise control. Most domestic and industrial motor applications use 3 ...

The ZXBM1021 from Diodes is a variable speed control solution for cooling fans, blowers, extractors, motors and pumps deployed in a variety of consumer and industrial products. The single phase, ...
