Abstract

PURPOSE: A stator for a coreless motor is provided to reduce the manufacturing cost of a motor by winding a core between slots. CONSTITUTION: A plurality of coupling grooves(11) is formed on a cylindrical internal surface of a housing(10). A plurality of teeth(22) is formed on an external surface of a coil winding unit(20). The plurality teeth(22) are inserted into the coupling grooves(11) to be fixed. A depth of each of slots(21) between the teeth(22) is deeper than that of the respective coupling grooves(11). A plurality of coils(30) is respectively wound between two different slots(21) of the coil winding unit(20). The teeth(22) between the slots(21) are divided into two groups: one is inserted into the coupling grooves(11) of the housing(10) and the other is not inserted thereinto. The coupling grooves(11) of the housing(10) are formed so as to be corresponded to the inserted teeth.
