Electrical machines and drives keep moving away from traditional technologies such as
brushed machines and wound field machines toward lighter,“easier to maintain” machines …

This paper overviews high-speed permanent magnet (HSPM) machines, accounting for
stator structures, winding configurations, rotor constructions, and parasitic effects. Firstly …

In an electrical machine design, thermal management plays a key role in improving the
performance and reducing size. End-windings are commonly identified as the machine hot …

More-electric aircraft (MEA) has become a dominant trend for modern aircraft. On-board
MEA, many functions, which are conventionally driven by pneumatic and hydraulic power …

This article overviews novel magnetic-field-shifting techniques for enhancing the torque in a
new class of asymmetric rotor pole interior permanent magnet (AIPM) machines. The …

Electric machines with high specific power are crucial for the more electric aircraft
propulsion. However, the harsh operating environment such as low air pressure and high …

Electric and hybrid-electric aircraft propulsion are rapidly revolutionising mobility
technologies. Air travel has become a major focus point with respect to reducing …

This paper presents a design environment for permanent-magnet synchronous motors
(PMSMs). Two design examples for electric vehicle (EV) traction are presented: one interior …

Compact and high speed electromechanical systems lead to higher and higher levels of
multiaxial mechanical stress, that may strongly change the magnetic behavior of materials …

This paper presents a novel high-speed alternating current (AC) homopolar motor/generator
design using stationary ReBCO excitation windings. Compact, lightweight, high-efficiency …
