Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...

Abstract: This paper presents the design and analysis of a novel machine family—the enclosed-rotor Halbach-array permanent-magnet brushless dc motors for spacecraft applications. The initial design, ...

The Yasa electric motor challenges conventional expectations of size and power in automotive engineering. Weighing just 12.7 kilograms (28 pounds), this compact axial flux motor delivers an impressive ...

Recent technological advances have opened new possibilities for the development of advanced medical devices, including tiny robots that can safely move inside the human body. Some of these systems ...

We’ve long-admired internal combustion engines for their power density pursuits. Extremely high horsepower-to-liter ratios for naturally aspirated cars like the Honda S2000, Ferrari 458 Speciale, or, ...

Hydrogen is an essential puzzle piece in removing carbon from our energy economy and reducing pollution, but it is not without its challenges. While the overarching goal is to electrify as much of the ...

Abstract: In this study, a axial flux compulsator (AFCPA) offers significantly higher energy and power density than traditional capacitor-based sources. With its natural ability to achieve current ...

Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...

Key components of the 1-MW motor. What comprises the 1-MW inverter system? A look at the channel-type heat-exchanger architecture to keep the system cool. Up to a few years ago, “flying cars”—vehicles ...
