Torque ripple reduction in brushless DC motors is a subject of intense study due to its significance in enhancing the performance, efficiency and longevity of motor drive systems across various ...

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

In a recent article, I wrote about step-motor system performance emphasizing key concepts that all engineers need to understand about this widely-used electro-magnetic-mechanical digital actuator. As ...

Design engineers know that both brush DC and brushless DC (BLDC) motors can operate as generators, but many tend to avoid running brushed DC motors in generating mode because they believe it is ...
