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 ...

A seemingly trivial circuit layout can be problematic because of the higher than usual currents that are common in motor-control circuits. Although the circuits that monitor three legs are slightly ...

In modern industrial and household applications, single-phase motors are widely used due to their simple operation and low cost. However, effectively adjusting their speed is a common challenge. This ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

A specialized segment of the electrical construction and maintenance industry, AC motor control is an area that requires specific knowledge in order to troubleshoot motors effectively and ensure ...
