In this paper we are designing a low-cost microcontroller-based speed control of BLDC motor. A DC Brushless Motor uses a permanent magnet external rotor, three phase of driving coils, one or more Hall Effect devices are used to sense the position of rotor, and the associated drive electronics. The coils are activated, one phase after the other, by the drive electronics as queued by the signals from the Hall effect sensors, they act as three phase synchronous motors containing their own variable frequency drive electronics.
