Current sensing in BLDC motor application - Application note
In the first step, the transistor T1 and T4 are close, the current flows through the winding A and B, in this manner the rotor moves to 60 °. In the next step the transistor T1 and T6 are closed. The current flows through the winding A and C and the rotor moves to more than 60 °. Some of BDLC motors have the hall sensor embedded in the motor.
