Constant Starting Torque Control of Wound Rotor Induction Motors [PDF]

IEEE Transactions on Power Apparatus and Systems, 1970
Constant starting torque of a wound rotor motor can be achieved by inserting a fixed external element consisting of resistances and reactances combination in the rotor circuit instead of using a saturable reactor or other feedback devices. This approach provides the desired starting characteristic at a low cost of starting equipment.

Linear Induction Motors with Modular Winding Primaries and Wound Rotor Secondaries [PDF]

IEEE Transactions on Magnetics, 2008
Linear induction motors commonly use double layer windings, which produce good sinusoidal travelling fields, but have relatively bulky end windings and use either half-filled slots or overhanging coil sides at the ends of the machine. Long stator systems are difficult since it is not possible to butt stator modules against each other.

Flux observer algorithms for direct torque control of brushless doubly-fed reluctance machines [PDF]

, 2009
Direct Torque Control (DTC) has been extensively researched and applied to most AC machines during the last two decades. Its first application to the Brushless Doubly-Fed Reluctance Machine (BDFRM), a promising cost-effective candidate for drive and ...

Comparative analysis of PID and neural network controllers for improving starting torque of wound rotor induction motor

, 2020
Unlike 3-phase squirrel cage induction motor, starting-up of 3-phase wound rotor counter part can be improved by adding an external resistance to the rotor circuit.Thus, leads to reduce starting current and increase starting torque.

Investigating Mitochondrial Viscosity in Ferroptosis‐Mediated Drug‐Induced Liver Injury using a Double‐Targeted Strategy

Advanced Science, EarlyView.
Utilizing a mitochondrial double‐targeted strategy, a novel near‐infrared fluorescent probe (FTZ‐2) is established for monitoring viscosity variations in ferroptosis‐mediated drug‐induced liver injury. In summary, this work provided a practical strategy for the early diagnosis and evaluation of liver injury.

Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

Advanced Science, EarlyView.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...

Alkaline Phosphatase‐Activated NIR‐II AIEgens Nanosystem for Surgical and Postoperative Closed‐Loop Therapy of Advanced Osteosarcoma

Advanced Science, EarlyView.
This study designed a tumor microenvironment‐responsive AIEgen nanoparticle for near‐infrared photoimmunotherapy, which inhibits primary tumors and metastasis by promoting pyroptosis and suppressing aerobic glycolysis. ABSTRACT In advanced osteosarcoma, tumor invasion often prevents complete resection, and immunotherapy is limited by the tumor's ...
