In this video, we focus on recycling copper from old broken electric motors into usable materials. The process includes extracting copper wires, melting the copper, casting ingots, forging them to ...

An open-end winding machine configuration and a suitable control strategy for medium-voltage ac motor drives applications are proposed in this paper in order to reduce the distortion of phase voltages ...

Series-end winding motor drive (SWMD) is a novel motor drive with both high dc voltage utilization and zero-axis current control capability, which can replace the role of open-end winding motor drive ...

It's a standard so high that it makes you wonder if the rulebook was written by a team of diabolically obsessive engineers.
