[Davide Gironi] shows us how to implement a sensorless brushless DC motor controller (sensorless BLDC) using an ATmega8 microcontroller. In order to control a BLDC motor you need to know its rotati… ...

Brushless DC (BLDC) motors are standard fare in low-precision, speedy RC applications. The control schemes needed to run them slowly or precisely go deep into motor theory and might put these motor… ...

CONSTRUCTION AND OPERATINGPRINCIPLE BLDC motors are a type of synchronous motor. Thismeans the magnetic field generated by the stator andthe magnetic field generated by the rotor rotate at thesame ...

Figure 2 compares the drive circuits of a typical brushed and BLDC motor. The brushed motor requires only a single gate driver and power FET.
