Motor. - Here is electronic SCircuit Schematic a Sensor-less Brushless DC Motor Driver based on NE555 and DRV10866 IC like in Figure 1 below. In this circuit schematic the basic component used is NE555 and DRV10866 IC. DRV10866 driver IC from Texas Instruments is used specially to drive a small three-phase Brushless DC motor (M). This IC have 10 pins connected like in Figure 1 above. According DRV10866 sheet data describe that a three-phase, sensor-less motor driver with integrated power MOSFETs having drive-current capability up to 680mA peak. DRV10866 is specifically designed for low noise and low component-count fan-motor drive applications. A 150° sensor-less back emf scheme is used to control the three-phase motor.
