자동차 연료펌프용 BLDC의 센서리스제어 기동기법

Start-up Strategy at Sensorless Control of BLDC for Vehicle Fuel Pump

This paper proposes a simple starting method to arrange the rotor position of the blushless DC motor (BLDC) without additional sensors and any information of motor parameters. Both the stator current and time period for arranging the rotor position can be easily adjusted by modulating a pulse width of switching devices. Using the proposed method, it is demonstrated experimentally that the BLDC starts up very smoothly.
