Among the electro-mechanical devices transforming energy from electrical to mechanical, squirrel cage induction motor can be surely considered a workhorse of industry due its robustness, low cost, and good performance when directly fed by ac grid. Being most influencing topology in terms consumption, optimizing efficiency motors could lead great impact toward reduction human environmental footp...

In industries, squirrel cage induction motors are critical for supplying rotary motion in power tools. This research presents a robust but simple framework an inter-turn fault classification at minor loading across diverse occurrence conditions, which is one of the most common defects motor. Early detection this issue to prevent system from completely failing as result it evolving more severe s...

Nowadays, finite element analysis represents the most accurate tool to analyse electrical machines. However, time domain resolution of electromagnetic problem, in some cases, requires long simulation due induced nature currents. The computational burden increases when machine features a skewed layout on stator or rotor structures, since this 2D multi-slices approximated even full 3D model. In p...

The advantages/disadvantages of energy storage devices, which can provide nonpolluting automobile systems are discussed. Four types of storage devices are identified: electro-chemical (batteries) hydrogen electro-mechanical (flywheels) Molten salt heat storage A high speed flywheel with a small permanent magnet motor/generator has more advantages than any of the other systems and might become a...

In this work, analyses of the effect full-, under-, and over-pitched stator winding configurations on efficiency, output power, torque characteristics, current voltage harmonic components are carried out a three-phase, squirrel cage induction motor. Performance have been performed both via Ansys/RMxprt Maxwell/2D software by modelling with coil pitches 100°, 120°, 140°, 160°, 180°, 200°, 220°, ...
