Nowadays, electric motors are widely used in the domestic, commercial and industrial sectors for the optimal consumption of electric energy, the design and construction of high-efficiency motors, etc. Meanwhile, brushless DC motors or (BLDCM) have been used in many industrial and non-industrial applications for reasons such as high efficiency, easy control method and high reliability, power density and high torque, and their use is increasing day by day. increase. A very big advantage of brushless DC motors is high efficiency because these motors can be continuously controlled with maximum rotational force (torque), in contrast to brush motors, which reach maximum torque only at certain points of rotation. The second advantage of BLDCM controllability is that it can be controlled using a feedback mechanism to deliver exactly the desired torque and rotation speed. Brushless DC motors have high durability and produce low electrical noise due to the absence of brushes. In the use of brushed motors, the brush and commutator are worn out due to continuous moving contact and also create sparks, therefore BLDC motors are often preferred in cases where it is important to prevent electrical noise. In this article, various control methods of BLDC brushless DC motors are discussed and various aspects of these motors and simulation results are discussed |
