Performance Analysis of a Rewound Multiphase Synchronous Reluctance Machine
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022 This paper analyses the performance of synchronous reluctance motors (SynRMs) when an existing three-phase stator is rewound to a higher number of phases. The introduced rewinding technique offers an optimized distribution for air gap flux, higher winding factor and higher value for the fundamental component of the magneto-motive force with lower ...

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...
