This application note discusses the Field Oriented Control (FOC) of 3-phase AC induction motors. Field Oriented Control is also referred to as Space Vector Control. Vector control provides efficient ...

This application note presents the Field Oriented Control (FOC) of a 3-phase AC induction motors. It demonstrates the use of Zilog’s Z16FMC ZNEO! 16-bit microcontroller to implement Vector Control of ...

MH Series high efficiency motors are rated at 80 to 92 percent efficiency. The new Lenze IE2 L-force three-phase asynchronous (AC) motors meet or exceed global regulations (IEC 60034-30) aimed at ...

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 ...

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 ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...

Art. 430 provides the requirements for motors. But at a whopping 27 pages, it is the largest article in the National Electrical Code (NEC). From a technical standpoint, it is arguably the most complex ...

When you order a new broadcast transmitter, one of the first questions will be about power. Is it single-phase or three-phase alternating current? If single-phase, it is 208 or 240 volts? If it is ...
