A stator of a dynamoelectric machine comprises an iron core formed by laminating irons sheets, armature coils received in slots of the iron core, a plurality of spacer blocks extending radially in contact with an end surface of the iron core, clamping end plates for clamping the iron core, and buffer boards located between the spacer blocks. The spacer blocks include long ones located between an outer periphery of the iron core and teeth portions thereof and short ones located between the outer periphery and the bottom portions of the slots. Each of the short spacer blocks is provided with a radially extending channel formed on the side surface facing to the end surface of the iron core and the channel has gas air outlet and one end opened on the side facing to the slot bottom to form an inlet for a cooling gas.
