Abstract: Open-circuit faults in three-phase voltage source inverters can cause unbalanced currents, high torque ripple, and excessive core losses in permanent magnet synchronous machines. To ...

Abstract: This paper proposes a virtual dodecagonal space vector structure-based speed range extension scheme for direct torque controlled (DTC) open-end winding permanent magnet synchronous motor ...

TOPEKA — The total price of constructing research and clinical facilities for the new University of Kansas Cancer Center increased nearly $80 million to accommodate plans for additional laboratory ...

The first warp drive design from the early 90s required massive amounts of negative energy, but three decades of honing the math later, scientists have lowered that threshold considerably. Now, a new ...

A team of scientists has developed a flexible, airless wheel that could one day fly to the Moon. The wheel comes in a compact form factor that can expand into a large, robust shape that is ideal for a ...

As the AI surge progresses, the most significant hurdle is unlikely to be the availability of chips or components. Instead, it will be electricity, cooling, and physical space. On our planet, data ...
