Brushless DC Motors have a permanent magnet rotor and the stator winding are wound such that the back electromotive force (EMF) is trapezoidal. The motor posses high Torque/weight ratio, operate at very high speed, very compact & electronically controlled. In this paper, we have to use three algorithms ZN, GA & PSO respectively. On the basis of performance of these three . The control of BLDC motors can be done in sensor or sensorless mode, but to reduce overall cost of actuating devices, sensorless control techniques are normally used. The advantage of sensorless BLDC motor control is that the sensing part can be omitted, and thus overall costs can be considerably Size: KB. BACK EMF DETECTION DURING PWM ON TIME BY ST7MC back EMF during PWM “off” time without the need to sense or re-construct the motor neutral in a sensorless BLDC motor drive system. Since this direct back EMF sensing scheme re- crossing detection is unsymmetrical in the ST sensorless drive system at high speed. It. Sensorless motor control works by measuring the voltage induced in the stator coils by the rotor magnets as they move past (this is called back EMF). Since this is directly related to rotor position and speed, it can be reliably used instead of an external sensor.
