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.

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 ...

[Guido] was recently commissioned to build a kinetic sculpture for a client who wanted something unique. What he came up with is really awesome. It’s called ORBIS: The Wooden Kinetic & Li… ...

rpm = (Hz) x (120) / (No. of motor poles) This is the simplest form of the equation. The more poles the motor has, the slower the RPM. Conversely, the fewer poles the motor has, the faster the RPM.

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, ...

Additionally, the control method used by the motor’s speed controller has a great impact on the precision and accuracy of speed management at low speeds. Print this page. Tweet; ...

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, ...
