IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.To address nonlinearity in high‐voltage flat‐wire EV motors, a new layering theory is developed for calculating stator natural frequency and frequency response functions. The method is validated by finite element analysis and experimental hammering tests, showing a significant improvement in simulation accuracy to within 1% for natural frequencies ...

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.Independently rotating wheelsets require accurate realization of traction and differential wheel torques under electrical constraints. This paper proposes a hierarchical control framework combining speed PI and LQ‐servo lateral guidance with scaling‐based torque allocation and a flux‐map current reference generator that accounts for DC‐link voltage ...

An artificial neural network approach for sensorless speed estimation via rotor slot harmonics
TURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2014 In this paper, a sensorless speed estimation method with an artificial neural network for squirrel cage induction motors is presented. Motor current is generally used for sensorless speed estimation. Rotor slot harmonics are available in the frequency spectrum of the current.

Electrical Engineering in Japan, 2007 AbstractSpeed sensorless vector controlled induction motor drives are the standard choice in many industrial applications, but this can hardly control torque and rotor speed at low speed. Recently, a method based on high‐frequency signal injection has been studied.
