This paper presents the system concepts and describes the circuit implementation of several key features. The increasing use of high-current brushless dc (BLDC) three-phase motors puts stringent ...

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 ...

Motor control integrated circuits (ICs) and motor drives are essential elements for implementing smart manufacturing within the framework of Industry 4.0. A common requirement in modern industrial ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...
