This file type includes high-resolution graphics and schematics when applicable. In the seemingly endless quest for higher motor performance and improved system cost efficiencies, motor manufacturers ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

We’ve all been to the trade shows where semiconductor vendors are showing their motor control solutions running a motor with a simple flag or disc to show that the motor is actually moving (I’m guilty ...

Before continuing with the explanation started in Part 2 of the switched-modeoperation, the timer and timing system for the ST7MC motor control cellneeds explanation. All motor timing is driven by one ...

Having reviewed the basics of BLDC motor control in Part 1, the design effort canbegin.. The first quest is to select a microcontroller. Looking in themarketplace there are several microcontrollers ...
