This prototype uses water cooling, PTFE rings, and 3D‑printed mounts to turn 200‑year‑old heat‑engine tech into a ...

This paper proposes an induction motor drive system capable of suppressing shaft voltage and electromagnetic interference (EMI). A filter developed for this system is characterized by sophisticated ...

The authors describe a simple control for a permanent motor drive that provides a wide speed range without use of a shaft sensor. Two line-to-line voltages and two stator currents are sensed and ...
