Variable air gap axial flux permanent magnet machine with mechanical field weakening
Field-weakening of electrical machines enables rotational speeds to exceed the rated values. This is particularly simple in some AC machines such as induction machines where the field strength magnitudes are determined hence controlled by a component of current in the stator windings. In …

An Efficient Wide-Speed Direct Torque Control Based on Fuzzy Logic Technique
… and control flux locus at very low speed. Under field weakening condition, when the speed is beyond the rated speed, the available power is limited and the speed range cannot be increased any more. A DTC control system based on Fuzzy Logic technology (FL) is proposed. The proposed system aims to …

The Connection Between X-Ray Binaries and Star Clusters in the Andromeda Galaxy
… loss of stars due to the cluster's gravitational field weakening (cluster evaporation), lead to stars leaving their birth clusters. This ejection can significantly influence the life cycle and characteristics of XRBs. Understanding these processes is crucial for comprehending the life history of …

Model, Design, and Control for Power Conversion in Wave Energy Converter System
… conditions. A model that can bring the multiple fields together, and provides an accurate prediction from irregular wave dynamics and non-ideal PTO mechanism is needed. A methodology that converts mechanical transmission equations into a circuit model is created. The equivalent circuits of …
