报告主要内容：
Traditionally, the torque ripple induced by the BLDC drive mode is considered as the major acoustic noise source of precision BLDC motors. In the presentation, the detail analysis and testing results are used to identify the roots of the noise sources, and the new research direction can thus be inspired in reducing the acoustic noise of BLDC motors with new drive mode.
