Analysis of a Three Phase Induction Motor Directly from Maxwell's Equations

, 2011
The torque developed in a three phase AC squirrel cage motor is usually expressed in terms of resistances and reactances of the stator, the rotor, and the motor as a whole. We use Maxwell's equations to find the torque in terms of geometrical parameters.

Analytical Models Synthesis of Power Electronic Converters

Transactions on Environment and Electrical Engineering, 2017
In this paper we proposes a synthesis of different mathematical models of power electronic converters based on Thevenin/Norton equivalent circuits. Those models, composed by impedances and harmonic noise sources, are helpful to predict the conducted ...

Hybrid of Thevenin and Norton Equivalent Circuits Analogous to a Source Equivalence Theorem in Electromagnetics

Celal Bayar Üniversitesi Fen Bilimleri Dergisi, 2020
According to the conventional perception among engineers, once a circuit is reduced to its Thevenin or Norton equivalent, the voltage and current may be determined only at the load, but not in the remaining parts. The other voltages and currents that exist in the remaining parts of circuit should be determined by returning to the original circuit ...

A Cost‐Effective Approach for Temporary Operation of Medium‐ and High‐Voltage Electric Motors Incorporating Damaged Stator Coils

IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.
This paper proposes an approach to remove the damaged coil from the stator.The functional characteristics of the electric motor in different modes are analysed using finite element software. ABSTRACT Stator inter‐turn and ground faults in medium‐ and high‐voltage (MV/HV) motors often require full stator rewinding, causing long outages and high costs ...

Impact of Cyberphysical Attacks on Load Tap Changers and Distribution System Voltage Stability

IET Smart Grid, Volume 9, Issue 1, January/December 2026.
In this paper, we analysed the impact of a cyberphysical attack manipulating the operation of the LTC. In addition, we analysed the effect of load drop and PV while LTC is being manipulated. The cyber vulnerabilities leading to the attack were explored. ABSTRACT Load tap changers (LTCs) play a critical role in voltage regulation, and their manipulation

Quantitative Analysis Method of Stability Ability for Renewable Electric Energy Delivery System

IET Smart Grid, Volume 9, Issue 1, January/December 2026.
In this paper, a novel stability ability quantification method based on the amplitude mapping model (AMM) for the GFL–GFM hybrid system is proposed and introduced. Using this method, a concise and practical expression of stability ability can be calculated and derived and the stability of the system can be quantitatively analysed.
