How does a dc motor operate, and what's the impact of back EMF? Difference between continuous and stall current. How is current regulation applied in dc motor drivers? Oftentimes, the motor driver and ...

Specifics about high-power-density motors (HPDMs). Applications best served with HPDMs. Why BLDCs are perhaps the most preferred among HPDM architectures. High power density is an important ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...

In this article, I’ll dig into a couple of things you need to know when it comes to using salvaged hard disc drive spindle motors. Most electronics hobbyists think that such hard disc drive spindle ...

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 ...

This document written by Steve Bowling, Application Segments Engineer at Microchip Technology, discusses how motor works and describes the AC induction motor, variable-speed ACIM control, and FOC.
