Performance of halbach magnetized brushless ac motors [PDF]
IEEE Transactions on Magnetics, 2003 In this paper, an anisotropic bonded NdFeB Halbach magnetised ring magnet, which is oriented in powder alignment system during injection moulding and subsequently impulse magnetised, is employed. The features of such a Halbach magnetised machine, in terms of the airgap field distribution, and the back-emf and cogging torque waveforms, etc.

Advanced deep-learning model for temporal-dependent prediction of dynamic behavior of AC losses in superconducting propulsion motors for hydrogen-powered cryo-electric aircraft [PDF]
Communications EngineeringSuperconducting motors offer high power density, compactness, and efficiency for hydrogen-powered cryo-electric aircraft, but AC operation in cryogenic temperatures produces thermal losses that must be estimated accurately and rapidly at the design stage

ac-Driven Atomic Quantum Motor [PDF]
Physical Review Letters, 2009 We invent an ac-driven quantum motor consisting of two different, interacting ultracold atoms placed into a ring-shaped optical lattice and submerged in a pulsating magnetic field. While the first atom carries a current, the second one serves as a quantum starter. For fixed zero-momentum initial conditions the asymptotic carrier velocity converges to a
