Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

To reap all the benefits that an electric motor drive can offer, choose one that's a perfect match for your application A speed control enables the motor to achieve maximum efficiency during all ...

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 ...

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 ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

What consumes more than half of the world's electricity and supports nearly every facet of industrial production? The answer is the AC induction motor. Although these motors typically tolerate ...

With time on my hands, I decided to try a technique that I noticed first in a L200 voltage regulator data sheet. It is fig 25 in STM’s ‘A Designer’s guide to the L200 voltage regulator’ (ST webpage ...

The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.
