Analysis of voltage vectors and realization method of torque ripple reduction for BLDCM
IET Power Electronics, Volume 15, Issue 9, Page 865-876, 24 July 2022., 2022 Abstract BLDCMs are widely used in automotive, industrial and intelligent equipment fields due to their high power density, simple control, and good dynamic performance. However, its non‐sinusoidal characteristics have brought problems such as turn‐off phase freewheeling to the research and application of BLDCM DTC.
