Somewhere in most engineering educations, there’s a class on induction motors. Students learn about shaded-pole motors, two-phase and three-phase motors, squirrel cage motors, and DC-excited motors.

Induction machines are widely shunned for EV propulsion because of their lower peak efficiency and larger volume and mass. DSD has set out to explore the viability of a high efficiency high specific ...

Geothermal power offers a stable, continuous source of renewable energy that could help power millions of homes while reducing dependence on fossil fuels. As governments worldwide pursue ...
