A high-current quad SPST analog switch can be configured as a full-bridge amplifier capable of driving low-power dc motors. By adding a sense resistor, an analog-to-digital converter (ADC), and a ...

Sponsored by Texas Instruments: With the driver ICs available today, brushed DC motor control is a snap to integrate in building-, home-, and industrial-automation applications. Motors are everywhere, ...

Controlling a small dc motor without speed control sounds like a trivial task; a switch or a relay should suffice. However, several problems accompany this approach. For one, the switch, because of ...

Hobby servos are nifty and useful for a wide range of projects. There’s nothing stopping you from building your own servos though, and you can even give them nifty features like 360-degree rotation In ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

It is estimated that the average car has around 80 electric motors - many due to motorists’ insatiable demand for greater comfort and convenience. In a top-range Mercedes-Benz, for example, there are ...

I have been trying to fix a little old milling machine I bought (and here), and needed a replacement motor controller. It is a Clarke DCM10, a variant of Sieg’s X1, sometimes knows as a ‘micro mill’.
