The CLA60MT1200NHB is a high-performance DT-Triac™ technology platform featuring higher di/dt and dv/dt ratings. It is typically used in applications such as softstart AC motor control, lighting and ...

This triac-based 220V AC motor speed controller circuit is designed for controlling the speed of small household motors like drill machines. The speed of the motor can be controlled by changing the ...

Electric motors in the developed world are consuming an enormous amount of energy. According to a report prepared in 2002 by Steven Nadel and colleagues at the American Council for an Energy Efficient ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

Vector Control, also known as Field Oriented Control or FOC is an AC motor control scheme that enables fine-grained control over a connected motor, through the precise control of its phases. In a ...

Diacs and triacs are often used for control of ac lines and are seeing increasing use in Internet-enabled line switches. However, the traditional approach of modeling them using bipolar transistors ...
