DIY e-bikes are often easy to spot. If they’re not built out of something insane like an old washing machine motor, the more subtle kits that are generally used still stand out when compared to a ...

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 ...

Art. 430, Part VII provides the requirements for motor controllers. The requirements for motor control circuits are in Part VI. What’s the difference? Part VI is about the supply power to motor ...

Many of us will have experimented with brushless motors, and some of us will have built our own controllers rather than using an off-the-shelf part. Doing so is a good way to understand their ...

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 ...
