Reduction of torque ripple in an electrolytic capacitor-less BLDC motor drive by simultaneous speed and torque control method

Brushless DC motors have been widely used in both industrial and non-industrial applications. Commercialization of these drives by reducing their price and increasing reliability, are among the main goals of manufacturers and researchers. These goals have been partially achieved by reducing the numb...
