Research on Torque Ripple Suppression of Open‐Winding BLDCM Based on Zero Vector
IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.Torque ripple suppression in OW‐BLDCM remains a major challenge due to their unique back‐electromotive force characteristics and phase‐off operation. To address this, we conduct a systematic theoretical analysis of zero‐voltage vector commutation and propose a novel zero‐voltage vector selection strategy to prevent simultaneous three‐phase conduction ...

QPRC-Based DC-Link Stabilization of IFZ-Converter Applied to Suppress CCR in BLDCM Drives
IEEE AccessThe brushless dc motor (BLDCM) drives are adversely affected by commutation current ripple (CCR), which leads to increased torque ripple and degraded performance. The dc-dc converter based-BLDCM drive topology is widely preferred to suppress CCRs.

Modeling and Simulation of Brushless DC Motor with Nonideal Back EMF
, 2011 The back electromotive force (EMF) waveform of brushless dc motor (BLDCM) is trapezoid. But it is not absolutely trapezoid because of motor manufacturing. In this paper, a method of modeling for BLDCM with nonideal back EMF is presented.

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.This article introduces an L‐shaped modular consequent‐pole PM machine with an asymmetrical hybrid pole structure (AHPLM‐CPM) for in‐hub e‐bikes, enhancing PM utilisation and flux‐focusing while reducing leakage flux. Multi‐objective optimisation minimises torque ripple and maximises torque, yielding an 80.4% higher PM utilisation ratio and 50% lower ...
