Brushless dc motor with large air gap
Electrical Engineering in Japan, 1997 The authors propose a new brushless dc motor for pumps, with a large air gap of 8 mm, compared with the conventional gap of 1 mm. The conventional pump system is composed of an induction motor, a magnetic coupling, and a magnetic rotor with vane. This rotor receives power from the magnetic coupling.

Assessment of torque components in brushless permanent-magnet machines through numerical analysis of the electromagnetic field [PDF]
, 2005 For the calculation of torque in brushless (BL) alternating current motors a local method is proposed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air gap.

Advanced Materials Interfaces, Volume 13, Issue 6, 16 March 2026.This study presents an experimental Proof‐of‐Concept of an electrified CO2${\rm CO}_2$ loop that combines DAC and GA‐plasma conversion. Atmospheric CO2${\rm CO}_2$ is captured and solidified as CaCO3${\rm CaCO}_3$, followed by plasma‐based calcination to regenerate CaO and with the possibility to split CO2${\rm CO}_2$ into CO for syngas synthesis.

Advanced Science, Volume 13, Issue 18, 27 March 2026.Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Analysis of a Novel Brushless Doubly Fed Reluctance Generator Based Wind Energy Conversion System
Energy Science &Engineering, Volume 14, Issue 3, Page 1226-1240, March 2026.BDFRG based grid connected wind energy conversion system. ABSTRACT This paper presents a grid connected Brushless Doubly‐Fed Reluctance Generator (BDFRG) based wind energy conversion system. It offers a reliable and cost‐effective solution since its brushless and cage‐less rotor structure eliminates the need for slip rings, reducing maintenance costs ...
