CORONAL STREAMERS REVEALED DURING SOLAR ECLIPSES: SEEING IS NOT BELIEVING, AND PICTURES CAN LIE



A New Approach of Minimizing Commutation Torque Ripple for BLDCM

The properties of brushless DC motor (BLDCM) are similar to the fractional, slot-concentrated winding of permanent-magnet synchronous machines, and they fit well for electric vehicle application.However, BLDCM still suffers from the high commutation torque ripple in the case of the traditional square-wave current control (SWC) method, where the cur
