H Bridge configuration is commonly used in electrical applications where the load needs to be driven in either direction. A typical H-Bridge structure is shown below; The current flows through the ...

We use DC fans in many systems in our day to day life. For example, CPU fans, fume extinguishers and many more appliances which we make use of, are operated by DC. This is a project used to control ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

This is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

Sensor-less brushless dc motors do not have to be hard to drive, claims Allegro MicroSystems. “Start-up and run commutation can be customised for individual motors and loads by adjusting a few default ...

Years ago my pal Steve Titus wanted to experiment with some drone rotor designs. He needed a simple motor controller that could operate from 8V to 12V and deliver amperes of current to a DC motor used ...

So your electronic hobby skills are coming along quite nicely but you’re not very comfortable doing more than blinking a few LEDs. Now’s a good time to try something new by driving a couple of DC ...

ROHM Co., Ltd. has developed two new motor driver ICs for brushed DC motors, BD60210FV (20V, 2ch) and BD64950EFJ (40V, 1ch), which are intended for use in home and office appliances such as ...

The DPW Series pulse-width-modulated dc motor-speed control designed in a compact SMT package. The RoHS-compliant models are rated from 2 to 10-A continuous output at 120/240 Vac. Machine Design ...
