Abstract
Recently, most machineries have been small size and mobile type. 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 motor but because of small size there is no position sensor such as hall sensor.
In this paper, we propose synchronous driving and control method for micro brushless DC motor without position sensor. We design and manufacture this controller and perform experiment to show the effectiveness of the proposed method.
