Brushless DC (BLDC) motors offer some significant advantages over other categories of electric motors, such as brushed motors. Compared with the latter, which are cheaper, BLDC motors require a ...

This file type includes high resolution graphics and schematics when applicable. When it comes to battery-powered products like handheld power tools, portable medical equipment, or home-automation ...

Brushless-dc motors are taking center stage in medical-equipment design because they last twice as long a competing technologies. • Sensorless brushless-dc-drives have evolved to a point where they ...

In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.

A Z-source Inverter (ZSI) is a DC-to-AC converter that can perform both buck and boost functions as a single stage. A unique attempt of ZSI is the shoot through state, by which two switches of the ...
