Abstract
A stator for an electric motor comprises: a plurality of segmented cores each having one yoke and at least one pole protruding from the yokes in a radial direction; a plurality of bobbins formed to receive the poles therein, having blocking walls extending from one side of ends of the poles in a circumferential direction thereby to block a space between the poles, and coupled to the poles; and stator coils wound on the bobbins. Accordingly, the temperature of the stator core and the stator coil are prevented from rising, and a noise occurrence is reduced. Also, a winding operation for the stator coil and a manufacturing process are facilitated.
