The main advantage of sensorless BLDC motor control is lower system cost and the main disadvantage is the motor must be moving at minimum rate to produce sufficient BEMF to be sensed. How it works: When the BLDC motor rotates, each winding (3 windings) generates BEMF opposes the main voltage. The 3 generated BEMF signals are 120° out of phase.

High Current Sensorless BLDC Motor Controller using Back EMF Homemade Circuit Projects
This paper provides a technical review of position and speed sensorless methods for controlling Brushless Direct Current (BLDC) motor drives, including the background analysis using sensors, limitations and advances. The performance and reliability of BLDC motor drivers have been improved because the conventional control and sensing techniques have been improved through sensorless technology.
Sensorless BLDC motor control with Arduino DIY ESC SIMPLE PROJECTS
One of the methods for sensorless BLDC motor control is to use the zero-cross points of back electromotive force [7-13]. Since the back electromotive force signal is not available, the zero-cross points are detected by the filtered voltages of the motor terminal. As the speed increases, filters impose more delay on the circuit which causes the.
PPT 3Phase Sensorless BLDC Motor Control Using MC9S08MP16 PowerPoint Presentation ID5191773
Sensorless BLDC motor control—sometimes called sensorless trapezoidal control of BLDC motors—uses back EMF (BEMF) for determining the location of the motor's rotor (the motor's rotating part) with respect to the motor's stator (the stationary part). A voltage applied across a motor's winding forces the motor's rotor to turn.
