Abstract: Disclosed herein is an assembly structure of a bearing and a holder of a brushless DC motor. The bearing is forcibly fitted into a hollow space formed through the holder. A beveled mouth edge is formed on the upper end of the circumferential inner surface of the holder through which the bearing enters the holder. Therefore, the assembly structure can enhance the workability of the process of assembling the bearing with the holder.

Abstract: Disclosed herein is a brushless DC motor that ensures stable driving of a shaft that rotates in a hollow of a bearing by using a bearing with a flat bottom surface and a tapered top. A contact height between an inner peripheral surface of the bearing and an outer peripheral surface of the shaft is larger than a contact height between an outer peripheral surface of the bearing and an inner peripheral surface of a bearing holder.

Abstract: There is provided a motor having an improved coupling structure between a circuit board and a base plate, and an optical disc drive using the same. The motor includes: a base plate; and a circuit board coupled to a surface of the base plate and having insulating layers formed on both surfaces thereof, wherein the insulating layers formed on both surfaces of the circuit board have different thicknesses. In particular, an insulating layer formed on one surface of the circuit board attached to the base plate may be thicker than an insulating layer formed on the other surface thereof.
