초록
Recently, most machineries have been small size and mobile type. And human body insertion type endoscope and micro robot technology has been developed. Then the motors used in this field are developed in micro size such as about 2mm in diameter. The structure of this motor is similar to a general brushless DC(BLDC) motor but because of small size there is no position sensor such as hall sensor. In this paper, we propose synchronous driving method for micro BLDC motor without position sensor. We design and manufacture this driver and perform experiment to show the effectiveness of the proposed method.
