Nevertheless, BLDC motors have come to dominate many applications: Consumer devices such as computer hard drives, CD/DVD players, and PC cooling fans use BLDC motors almost exclusively. Low speed, low power brushless DC motors are used in direct-drive turntables. High power BLDC motors are found in electric vehicles and some industrial machinery.

Brushless DC motors are high efficiency motors which are used across a wide variety of applications. These motors require more robust control algorithms then their brushed DC counterpart. BLDC motors are synchronous motors that require a 3-phase AC signal to drive them. This note will give a brief overview of BLDC motor control as well as give ...

Brushless dc motors (BLDC) are one of the motor types rapidly gaining popularity. The construction of modern BLCD motors is very similar to the ac motor, known as the permanent magnet synchronous motor. BLDC motors come in single-phase [1], 2-phase and three-phase configurations [2]. Out of these, the 3-phase motors are the most popular and ...
