Start-up of Sensorless Brushless DC Motor Based on Open Phase Voltage Measurement

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 instant of the first commutation 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.
