Abstract
A PM brushless DC motor can be sensorlessly controlled using phase voltage or terminal voltage. However, such control might cause a detection error of the rotor position. This paper computes and analyzes the detection error and the motor commutation angle, and presents an error compensation circuit to make the motor commutate normally. Experimental results are included to verify the computation equations and the compensation circuit
