Next is the H-bridge, which resembles an H (Figure 2), which is used typically with a brushed DC motor. In addition to run, coast, and break operating modes, it can also reverse a motor. Simplified ...

The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is defined using the space vector modulation (SVM) ...

3-phase BLDC motors are widely used in modern electronic devices such as hard, floppy and CD-ROM drives as well as other consumer and industrial equipment. BLDC motors have a straight-line, ...

While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

Having both 3-phase and single-phase loads can be challenging when trying to balance the voltages at a facility. It’s possible that during a facilities operation, one phase can be lightly loaded ...

There are several reasons to use a three-phase inverter to run a single-phase induction motor, including isolation from variable power grids, reduction of peak currents and elimination of the starting ...

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 ...
