Abstract: This article presents an open-circuit fault diagnosis approach for the drive inverter system in a permanent magnet synchronous motor. This method can detect weak faults, and extract key ...

For those who have worked on vessels for many years, the increasing complexity may be a sore point, especially for those who have been hands-on in their careers and been zapped a few times. George ...

Dual three-phase permanent magnet synchronous motor (DTPPMSM) has drawn increasingly attentions in transportation fields, such as electric vehicles (EVs), hybrid vehicles (HCs), and more electric ...

Physicists in China have observed five phases in localization physics within a single quantum system. Using an advanced ...

Providing power via contact-closure circuits historically required a new third wire, but perhaps no longer. Say the words “solid-state relay” (SSR) and most engineers also naturally think of two ...

Thirteen years ago, I was on the brink of death. My nearly year-long battle with anorexia nervosa had reached a tipping point: tests showed my heart could give out at any moment, and I was rushed to ...

We are providing an unedited version of this manuscript to give early access to its findings. Before final publication, the manuscript will undergo further editing. Please note there may be errors ...

DENVER — Gov. Jared Polis on Thursday declared a statewide drought emergency as he activated Phase 3 of the state’s drought response plan. Colorado’s record‑low snowpack and the extreme warmth have ...

In just a month’s time, tourists are expected to flood Philadelphia’s Independence National Historical Park in anticipation of celebrations for the 250th birthday of the United States on July Fourth.

Article 240 provides the general requirements for overcurrent protection and overcurrent protective devices (OCPDs). The job of an OCPD is to open the circuit if the current reaches a value that may ...
