| Abstract |
This paper presents a method for start-up of sensorless brushless DC motor. A specific switching
technique is applied to bring the motor speed to a threshold value required for regular sensorless
operation. The procedure is based on bringing the rotor in the known position and determination of the
first commutation instant by a special experiment. The start-up procedure is integrated with the back
EMF zero-crossing detection sensorless strategy and tested on the laboratory setup. |
