    Closed Loop Control for a Brushless DC Motor to Run at the Exactly Entered Speed

      Closed Loop Control for a Brushless DC Motor to Run at the Exactly Entered Speed

      Closed loop control for a brushless dc motor to run at the exactly entered speed is a system that controls the BLDC (brushless dc) motor speed according to the user defined speed. In other words, this system runs the motor at 25%,50% or 75% of the total speed when user set this percentage of speed […]
