Causal Scale of Rotors in a Cardiac System [PDF]
Rotors of spiral waves are thought to be one of the potential mechanisms that maintain atrial fibrillation (AF). However, disappointing clinical outcomes of rotor mapping and ablation to eliminate AF raise a serious doubt on rotors as a macro-scale ...

Performance of multi-stage axial-flux machines with MMEs
This study covers the investigation into the reduction of rare-earth magnets in a permanent magnet (PM) machine via the use of multiple rotors to enable a PM generator to be comprised of mixed magnetic elements, hereafter referred to as MME, by ...

Novel partitioned stator hybrid excited machines with magnets on slot openings
In this study, a novel partitioned stator hybrid excited machine is proposed, in which the excitation sources including both permanent magnets (PMs) and field windings are allocated on the secondary stator that is separated from the original stator ...

Space modulation profile modelling for steer-by-wire SMPMSM
This paper presents a sensorless estimation algorithm for steer-by-wire applications based on the injection of a high-frequency rotating voltage. Enhancement to the basic sensorless algorithm through SMP look-up tables is proposed.
