Method for the arrangement of a drive unit in a revolving door

1. A method for installing a drive unit ( 10 ) in a ceiling element ( 11 , 16 ) of a revolving door, the ceiling element ( 11 , 16 ) of the revolving door being configured to receive and engage the drive unit ( 10 ), the drive unit being configured to drive a turnstile ( 12 ) of the revolving door, the method comprising:

securing an adapter element ( 13 , 22 ) to an underside of the ceiling element ( 11 , 16 );

securing an electronically commutated multipole motor ( 14 ) having an output shaft ( 31 ) and tooling openings ( 30 ) to the adapter element ( 13 , 22 ); and

adjusting, by one or more adjusting portions ( 19 ) of the adapter element ( 13 , 22 ), alignment of the output shaft ( 31 ) of the multipole motor ( 14 ) relative to a rotational axis ( 18 ) of the turnstile ( 12 ) of the revolving door, the one or more adjusting portions ( 19 ) being accessed for the adjusting via the tool openings ( 30 ).

2. The method according to claim 1 , further comprising gearlessly connecting the output shaft ( 31 ) of the electronically commutated multipole motor ( 14 ) to revolving wings ( 23 ) of the turnstile ( 12 ) of the revolving door.

3. The method according to claim 1 , further comprising a step, prior to the step of securing an adapter element ( 13 , 22 ), of securing, by a pre-fixing portion ( 15 , 24 ), the multipole motor ( 14 ) to the adapter element ( 13 , 22 ).

4. The method according to claim 1 , wherein the adapter element ( 13 , 22 ) and the multipole motor ( 14 ) are mounted, with respect to one another, along a common mounting direction ( 17 ), the common mounting direction ( 17 ) coinciding with the rotational axis ( 18 ) of the turnstile ( 12 ).

5. The method according to one claim 1 , further comprising providing at least one under ceiling element ( 20 ) under the ceiling element ( 11 , 16 ), the under ceiling element being secured to the adapter element ( 13 ).

6. A system in which a drive unit ( 10 ) is arranged in a revolving door, the revolving door having a ceiling element ( 11 , 16 ) configured to receive and engage the drive unit ( 10 ), the drive unit ( 10 ) being connected to the ceiling element ( 11 , 16 ) so as to drive a turnstile ( 12 ) of the revolving door, the system comprising:

the drive unit ( 10 ), the drive unit ( 10 ) having an electronically commutated multipole motor ( 14 ) having an output shaft ( 31 ) and tool openings ( 30 ), the multipole motor ( 14 ) being arranged at the ceiling element ( 11 , 16 ) and gearlessly connected to the turnstile ( 12 ); and

an adapter element ( 13 , 22 ) configured to:

(i) secure the electronically commutated multipole motor ( 14 ) at the ceiling element ( 11 , 16 ), and

(ii) adjust, by one or more adjusting portions ( 19 ) of the adapter element ( 13 , 22 ), alignment of the output shaft ( 31 ) of the multipole motor ( 14 ) relative to a rotational axis ( 18 ) of the turnstile ( 12 ) of the revolving door, the one or more adjusting portions ( 19 ) being configured to be accessible for the adjusting via the tool openings ( 30 ).

7. The system according to claim 6 , wherein the adapter element ( 13 , 22 ) has one or more pre-fixing portions ( 15 , 24 ) configured to mount the multipole motor ( 14 ) to the adapter element ( 13 ).

8. The system according to claim 4 , further comprising at least one under ceiling element ( 20 ) under the ceiling element ( 11 , 16 ), the under ceiling element being secured to the adapter element ( 13 ).

9. The system according to claim 6 , further comprising an illumination device arranged at at least one location selected from a group of locations consisting of at the adapter element and at the multipole motor, the illumination device annularly surrounding the multipole motor.
