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 ...

This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

Designed with a bridge-tied-load (BTL) drive architecture in order to reduce audible switching noise and electromagnetic interference (EMI), the AM9468 and AM9469 brushless DC motor drivers from ...

Another method worth considering in any discussion of motor control isvector control. The detailed formulation of this method to control thetorque and flux in PMSM was originally achieved by Jahns, ...

The 555 timer IC is a handful of active components all baked into one beautifully useful 8 pin package. Originally designed for timing purposes, they became ubiquitous parts that can achieve almost ...

This file type includes high resolution graphics and schematics when applicable. This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors ...

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 ...

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 ...

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

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 ...
