A Brushless DC (BLDC) motor is an electronically commutated motor that operates using a DC power source. However, controlling the speed of BLDC motor can be challenging, as it requires precise timing and coordination between the motor's windings and the driving circuit. Without a controller, the speed of a BLDC motor may fluctuate, leading to performance issues, including decreased efficiency, increased wear and tear, and potential damage to the motor. In industrial applications where BLDC motors are used, precise speed control is essential for ensuring the motor operates at peak efficiency and avoids potential damage.
