Abstract
This paper proposes the novel sensorless control algorithm for 3-Phase BLDC motors with trapezoidal back-EMF. The proposed algorithms include both the new back-EMF estimation method by using the DC current model and a compensator for the electric parameter errors of the BLDC motor to improve performance of sensorless control more exactly. The back-EMF can be easily calculated from the electrical voltage equation. However, it has some errors at...
