A method for assembling a stator structure of a motor comprises providing a stator coil and a stator frame. The stator coil has a wire with an end segment and the stator frame includes a connector and a conductor. The conductor has an open-barrel crimping portion and a temporary holding portion. The method further comprises positioning the end segment of the wire in the crimping portion and a tip end of the end segment in the temporary holding portion. The method further comprises crimping the crimping portion to the end segment of the wire to electrically connect the connector and the end segment of the wire by penetrating an insulating coating of the end segment.
