Abstract
A capstan-motor assembly for a magnetic recording/reading apparatus comprises a bearing holder fixed to a motor frame on a main deck for rotatably supporting a shaft; a stator core coupled to the bearing holder, and on which a coil is wound; a rotor frame coupled to the shaft so as to be rotated together with the shaft, and in which a magnet corresponding to the coil is supported; and a PCB substrate disposed between the stator core and the motor frame, and electrically connected with the coil. The bearing holder has a soldering boss soldered to the PCB substrate and/or the stator core so as to protrude to outer surfaces thereof, thereby reducing components needed to affix PCB substrate and stator core to the bearing holder.
