چکیده
Brushless direct current (BLDC) motors are high efficiency synchronous that employed in a variety of applications due to prominent features such as long operational life, low maintenance requirements, and great dynamic response. BLDC driven by energizing the motor stator windings with an inverter circuit. To commute switches, trapezoidal (120°) method is generally used considering back electromagnetic force induced on unenergized phase BLDC. Furthermore, depending application alternative commutation modes (CM) 180°, 150°, sinusoidal-based approaches utilized. In literature, performance comparison some CMs was studied for two-phase operation three-phase mode switching pattern. However, only few research assessed two or three simultaneously. this study, pulse width modulation (PWM) based examined 120°, 150° modes, sinusoidal PWM. scope, it first time digital synthesis (DDS) addressed control algorithm study. experimental studies, simple low-cost drive circuit designed acquire case results. According results, proposed DDS-based sine more efficient than other methods has lower power consumption at both speeds also wider operable speed range.
