Abstract : Nowadays in every rotary application, electrical motors are used. Earlier, commercial applications commonly used single-phase induction motors, which were generating noise as well as vibrations mainly due to the irregular / uneven torque. For single-phase motor, efficiency is approximately 60-70% at full load. Vibration is generated due to fluctuating stator magnetic field causing irregularities in the torque. This vibration in the single-phase motor leads to generation of noise when operated. Along with it, low PF is of the main causes to impact the Efficiency. On the other side, one must take into consideration its low auxiliary torque and large size of the motor. To overcome the disadvantages of single-phase motors, BLDC (Brushless DC) motors are introduced in commercial applications. BLDC generates constant magnetic field which favors in generating the constant torque of the motor. This constant torque reduces vibration as well as noise. Whereas the efficiency of BLDC is roughly in between 85 to 90% with its compact size. This paper mainly focuses on the benefits of BLDC over single-phase motors with respect to vibration, noise, and efficiency. Scalar control and Vector control strategies are used to control the speed of BLDC motors. Considering effective motor controlling strategies, vector control strategies are commonly used though they are complicated. Keywords - Brushless DC Motor, Single-phase Induction Motor, Power Factor, Field Oriented Control, Integrated Power Module.
