초록
This paper presents a sensorless speed control of Brushless DC motor using terminal voltage of one phase. Rotor position information is extracted by indirectly sensing the Back-EMF from only one of the three terminal voltages for a three phase BLDC motor. This is a advantage for the cost saving and size reduction. Also, it can be substituted for conventional Hall-IC or encoder applied to position control.
