Claim:
1. A single rotor type motor comprising: a stator including a plurality of stator cores that are split and radially arranged, a bobbin made of an insulating material and wrapped on an outer surface of each of the stator cores, coils wound on an outer surface of the bobbin, an upper fixing plate that is disposed on the upper surfaces of the stator cores and on which the stator cores are radially arranged, and a lower fixing plate that is disposed on the lower surfaces of the stator cores and is coupled with the upper fixing plate, the stator cores being fastened to both the upper fixing plate and the lower fixing plate, wherein the stator core comprises: a rod portion of a plate shape and around which the coils are wound; a tooth portion that is extensibly formed in a lateral direction on one end of both ends of the rod portion and that is disposed facing a magnet of the rotor; and a flange portion that is formed at the other side end of the rod portion, in which the flange portion comprises: a connecting portion for mutually connecting between the stator cores; and a bolt fastening hole for coupling the stator core, the upper fixing plate, and the lower fixing plate with a fastening bolt; and a single rotor disposed with a certain gap from any one surface of an inner surface of the stator and an outer surface thereof, wherein a plurality of wiring units for electrically connecting between the coils wound around each of the stator cores are formed integrally on the upper surface of the upper fixing plate, wherein each of the wiring units comprises: a terminal pocket that is integrally formed on the upper surface of the upper fixing plate and into which the coils are inserted; and a coil terminal that is made of a metallic material that can be electrified and is inserted into the terminal pocket for electrically connecting between the coils, and wherein the lower fixing plate is configured in the form of a disc whose central portion is opened, in which first fastening bolt holes that are communicated from and coupled with the bolt fastening holes of the stator cores are formed at predetermined intervals in a circumferential direction of the lower fixing plate, first fixing holes that are in contact with a lower surface of the upper fixing plate and are communicated from the first fastening holes are formed at predetermined intervals in the circumferential direction of the lower fixing plate, and a cover portion extending from an outer surface of the stator and covering the lower surfaces of the stator cores is formed.
