  • Abstract
    Torque ripple generated in the commutation interval is one of the main drawbacks of Brushless DC (BLDC) motors. This paper presents an comprehensive analysis on the generated torque ripples of trapezoidal back-EMF due to phase commutation in the six switch, three-phase inverter brushless dc motor drives. Experimental results verify the amplitude of the torque ripple under 4 kinds of PWM pattern, respectively.
