Impeller machine and method for mounting an impeller machine

1. An impeller machine with an impeller housing ( 15 ) and a motor housing ( 19 ), wherein the motor housing ( 19 ) is arranged in an interior of the impeller housing ( 15 ), with a plurality of aerostators ( 20 ) which form a connection between the impeller housing ( 15 ) and the motor housing ( 19 ), and with a cable ( 26 , 30 ) which extends between the impeller housing ( 15 ) and the motor housing ( 19 ), wherein each of the plurality of aerostators ( 20 ) comprises an aerostator body ( 34 ) and an aerostator cover ( 35 ), wherein the aerostator body ( 34 ) and the aerostator cover ( 35 ) together span a contour in the form of an aerofoil profile, and wherein the cable ( 26 , 30 ) is guided in a cavity ( 32 ) which is arranged between the aerostator body ( 34 ) and the aerostator cover ( 35 ) of at least one of the plurality of aerostators,

said impeller machine comprising a cover component ( 38 ), in which the aerostator cover ( 35 ) for a first aerostator body ( 34 ) and the aerostator cover ( 35 ) for a second aerostator body ( 34 ) are combined into a unitary component.

2. The impeller machine of claim 1 , wherein the plurality of aerostators ( 20 ) extend between the impeller housing ( 15 ) and the motor housing ( 19 ).

3. The impeller machine of claim 1 , wherein the cavity ( 32 ) is open towards the outside through the impeller housing ( 15 ).

4. The impeller machine of claim 1 , wherein the cavity ( 32 ) is open towards the inside through the motor housing ( 19 ).

5. The impeller machine of claim 1 , wherein the cable ( 26 , 30 ) has a first end which is arranged radially inside the motor housing ( 19 ), and a second end which is arranged radially outside the impeller housing ( 15 ).

6. The impeller machine of claim 1 , wherein a recess ( 36 ) is formed in the aerostator body ( 34 ) for receiving the cable ( 26 , 30 ).

7. The impeller machine of claim 6 , wherein the recess ( 36 ) is open towards the rear end of the aerostator body ( 34 ).

8. The impeller machine of claim 1 , wherein the aerostator cover ( 35 ) is detachably connected to the aerostator body ( 34 ).

9. The impeller machine of claim 1 , wherein the cover component ( 38 ) has a central portion which forms a cover for the rear end of the motor housing ( 19 ).

10. A method for mounting an impeller machine with the following steps:

a. inserting a motor ( 16 ) in a motor housing ( 19 );

b. connecting the motor housing ( 19 ) to an impeller housing ( 15 ) with a plurality of aerostator bodies ( 34 );

c. arranging a cable ( 26 , 30 ) along at least one aerostator body ( 34 );

d. attaching an aerostator cover ( 35 ) to each of the aerostator bodies ( 34 ) wherein the aerostator body ( 34 ) and the aerostator cover ( 35 ) together span a contour in the form of an aerofoil profile, so that the cable ( 26 , 30 ) is arranged in a cavity ( 32 ) between the aerostator cover ( 35 ) and the aerostator body ( 34 ) of the at least one aerostator body ( 34 ); and

e. combining a first aerostator cover ( 35 ) and a second aerostator cover ( 35 ) with a cover component ( 38 ) to form a unitary component.

11. The method of claim 10 , wherein an aerorotor ( 14 ) is connected to the motor ( 16 ).

12. The method of claim 10 , comprising:

f. configuring the unitary cover component ( 38 ) to have a central portion which forms a cover for the rear end of the motor housing ( 19 ).
