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, ...

Each motor branch circuit must be protected against short circuit and ground faults by an overcurrent device sized no greater than the percentages listed in Table 430.52. A branch-circuit ...

When motors start across the line, they typically draw five times the running current. This temporary “inrush” is an overload condition. To handle inrush while still providing adequate overcurrent ...

This application note presents the vector control of a 3-phase AC induction motor using the Z8FMC16100 microcontrollers. This document also briefly describes the series of Z8FMC16100 flash ...

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) ...

ST is aiming at compliant 3 phase watt meters with an evaluation kit built around the STPMS2 double channel 24bit second-order ΣΔ modulator. Called EVALSTPM-3PHISO, it measures through a voltage ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

It's hard to stay up to date when you are floating in a sea of technical jargon. However, it's imperative that engineers know the terminology associated with the areas in which they work. And that's ...

What You’ll Learn: The origins of Permanent Magnet Brushless DC motors (PMDC). How the efficiency of electric motors increases as you increase the number of phases. How to optimally control stators as ...
