なる。(Object of the invention) This issue E7. The purpose of ' is to eliminate the above-mentioned drawbacks, by installing two outer rotor type electric motors on one main shaft, and incorporating the rotor directly into the runner hub of the runner. It is an object of the present invention to provide a reversible axial flow blower in which the axial dimension of the blower is significantly shortened, the number of parts is reduced, and the air flow is extremely good, and further,
When a pole change motor is used to control the rotation speed of the two motors according to the required air volume and wind pressure, and to take measures such as energy saving and noise reduction, the rotor core becomes large. Since the rotor core is built directly into the runner hub, the outer diameter of the motor can be small, which is extremely advantageous in terms of blower design.

FIG. 2 shows a sectional view including the axis T-I of the reversible axial flow blower of the present invention. Further, in the figure, the suction side of the reversible axial flow blower is indicated by arrow A, and the discharge side thereof is indicated by arrow B. Main shaft 1 stays 14.15 against casing 16
It is fixed both in the rotational direction and in the axial direction. ! A stator 2 of an electric motor is fixed to a main shaft 1 on the ground side, a rotor 4 corresponding to the stator 2 is fixed to a runner hub 7, and a bracket 17 is fastened to the runner hub 7. The center of the rotating support body consisting of the runner hub 7 and the bracket 17 is rotatably supported by the main shaft 1 via bearings 10 and 11e. Runner plate 6 is attached to runner hub 7.
is fixed. In other words, the casing of the electric motor, that is, the rotor frame, also serves as the runner hub 7, and the plate 6 of the runner is fixed to the outside of the casing of the electric motor. On the discharge side B of the reversible axial flow blower, another stator 5 is fixed to the main shaft 1, and the rotor 5 corresponding to the stator 6 is connected to the runner hub 9.
and a bracket 18. The runner hub 9 and the bracket 18, which constitute a rotating support, are rotatably supported on the main shaft 1 via bearings 12,19. The outside of the runner hub 9 (on which the plate 8 of the runner is fixed. Each stator 2°60
Lead wires 29.30 from the windings pass through the hollow part of the main shaft 1 and are attached to the terminal box 31.3 in the casing 16.
It has been pulled out to 2.
