Abstract: This article presents a unified control framework that combines sensorless flux-vector control and volts-per-hertz (V/Hz) control for induction machines. Within this framework, ...

Accurate measurement of low-frequency electric fields remains an important task. However, conventional electric-field sensing technologies often struggle to combine traceability, small scale, and ...

There are two inevitable imperatives when it comes to EV motors: the integration of wide-bandgap (WBG) power electronics and the need for high-accuracy motor control techniques. For one, as 200mm SiC ...

Controlling motor speed with variable frequency drives (VFDs) can save energy. But it’s not as easy as just adding a VFD. This article examines what else needs to be considered for motor control ...

Everybody farts. The question is how often? And how much gas is too much gas to pass? Those are questions that arose from frustration with a piece of lab equipment. To see the fart sensor in action, ...

“Coercive control” is the term for a diabolical relationship pattern that can have devastating consequences. It occurs when one person unreasonably interferes with another person’s free will and ...

Let’s face it: As we age, our vision and balance aren’t what they used to be. These changes to our senses can be minor annoyances but can also lead to injury, from stubbed toes to serious falls.

General Motors has released a new customer satisfaction program (CSP) for certain units of the Chevy Equinox EV and Chevy Blazer EV, addressing a potential issue with the all-electric crossovers’ ...

Abstract: This paper proposes a solar photovoltaic and battery-integrated drive system for light electric vehicles using a sensor-less vector-controlled permanent magnet-assisted synchronous ...
