Brushless DC – BLDC Motor Driver Circuit using 555 Timer IC

This article describes a sensor-less BLDC motor driver circuit using 555 timer and DRV10866 motor driver IC, suitable for driving small 5V BLDC fans without position sensors. The rise in the use of brushless DC motors (BLDCs) is driven by their efficiency, durability, and precision. However, controlling these motors typically requires rotor position information to […]
