ABSTRACT:
A stator for an electric motor is provided. The stator includes segmented cores each having one yoke and at least one pole protruding from the yoke in a radial direction, bobbins formed to receive the at least one pole therein, having blocking walls that extend from one side of ends of the at least one pole in a circumferential direction thereby to block a space between the at least one pole, and coupled to the at least one pole, and stator coils wound on the bobbins. A temperature of the segmented cores and the stator coils are prevented from rising and a noise occurrence is reduced.
