FPGA-based implementation of the back-EMF symmetric-threshold-tracking sensorless commutation method for brushless DC-machines [PDF]

open access: yes, 2013
The operation of brushless DC permanent-magnet machines requires information of the rotor position to steer the semiconductor switches of the power-supply module which is commonly referred to as Brushless Commutation. Different sensorless techniques have

Effective Variable‐Speed Bearing Fault Diagnosis From Motor Current Signals Using Kurtosis‐Guided VMD and Multi‐Branch Convolutional Neural Network

open access: yesIET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This study presents a novel deep learning‐based fault classification framework utilising Variational Mode Decomposition (VMD) for adaptive feature extraction and a Multi‐branch Convolutional Neural Network (M1D‐CNN) architecture for classification. The VMD hyperparameters were optimised based on kurtosis to ensure the extraction of the most informative

Mitigation of cross-saturation effects in resonance-based sensorless switched reluctance drives [PDF]

open access: yes, 2010
The stator and rotor yoke in a switched reluctance motor form magnetic circuit parts that are typically shared by different phases. If these parts saturate due to the excitation of one phase, this will lead to a change of the magnetic characteristics of ...

Sensorless control of deep-sea ROVs PMSMs excited by matrix converters [PDF]

open access: yes, 2005
The paper reports the development of model-based sensorless control methodologies for driving PMSMs using matrix converters. In particular, experimental results show that observer-based state-estimation techniques normally employed for sensorless control

A Study on the Down‐Scaling of Transient Drive Cycles for Experimental Analyses With Laboratory Based Small Motors

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
A new down‐scaling method for the laboratory based analysis of transient drive cycles is proposed and analysed. In contrast to the typically used dimensionless per unit steady‐state operating‐point based scaling methods, this approach also considers information on the cycles' transient characteristics in the scaling process. ABSTRACT Standardised drive

Performance analysis and comparison of PMSM with concentrated winding and distributed winding

open access: yesArchives of Electrical Engineering, 2020
The concentrated winding (CW) is obviously different from the traditional distributed winding (DW) in the arrangement of windings and the calculation of winding factors, which will inevitably lead to different performances of the permanent magnet ...

PMSM position-sensorless control method for optimizing fluctuating high-frequency signal injection

open access: yesXi'an Gongcheng Daxue xuebao, 2023
In the position sensorless control method of permanent magnet synchronous motor (PMSM) based on fluctuating high-frequency signal injection, the use of band pass filter (BPF) increases the system phase delay, resulting in poor observation performance, we
