Comparative Performance of Induction Motor Speed Controller System with Flux Weakening Control
IOP Conference Series: Materials Science and Engineering, 2021 Abstract In general induction motor not work optimally because cannot reach the maximum speed of the rating. In this paper, simulation is used with several methods, named Maximum Torque Per Ampere (MTPA) and Field-weakening. Simulation of the methods used the function on MATLAB C-Mex and implemented on block of Simulink.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
