Abstract

An electric motor with an electronics housing ( 6 ) includes a removable cover ( 10 ) as well as an operating unit. The operating unit includes an operating panel ( 20 ) fastened on the cover ( 10 ). The cover ( 10 ) with the operating panel ( 20 ) is connectable to a lower part ( 8 ) of the electronics housing ( 6 ) in at least two alternative alignments. A pump assembly is also provided with such an electric motor.

First claim

The invention claimed is:

1. An electric motor comprising:
an electronics housing comprising an electronics housing lower part and an electronics housing removable cover; and
an operating unit comprising an operating panel fastened on the electronics housing removable cover, and the electronics housing removable cover with the operating panel is connectable to the electronics housing lower part of the electronics housing in at least two alternative alignments, the operating panel comprising user actuated operating elements, wherein the operating panel is visible from a position outside of the electronics housing, wherein the operating unit, apart from the operating panel, comprises an electronics unit which is arranged in the electronics housing lower part in a manner separated from the electronics housing removable cover and which cooperates with the operating panel.

2. An electric motor according to claim 1 , further comprising:
a stator housing, the electronics housing lower part being connected to the stator housing, the electronics housing lower part and the electronics housing removable cover defining an interior space for one or more electronic components when the electronics housing removable cover is in contact with the electronics housing lower part, the stator housing comprising a stator housing interior space, wherein a stator and a rotor of the electric motor are arranged in the stator housing interior space, the electronics housing removable cover having an electronics housing outer surface, said electronics housing outer surface defining an operating panel recess, at least a portion of the operating panel being arranged in the operating panel recess, wherein interfaces of the electronics housing removable cover which come into contact with the electronics housing lower part are formed mirror-symmetrically to a middle line of the electronics housing removable cover.

3. An electric motor according to claim 1 , wherein the operating panel is a purely mechanical component which is free of electric components.

4. An electric motor according to claim 1 , wherein the electronics unit can be fastened in at least two alignments, each of the at least two alignments corresponding to one of the at least two alternative alignments of the electronics housing removable cover, in the electronics housing lower part.

5. An electric motor according claim 1 , wherein the electronics unit is fixed in the electronics housing lower part via at least one locking element.

6. An electric motor according to claim 1 , wherein the operating panel is provided with at least one transparent window, and the electronics unit is provided with at least one display element which is placed below the window.

7. An electric motor according to claim 1 , wherein the operating panel is provided with at least one elastically deformable push region, and the electronics unit comprises at least one electrical switch element which is placed below the push region.

8. An electric motor according to claim 1 , wherein the electronics unit is electrically connected via at least one plug connection and/or cable connection to further electronic components arranged in the electronics housing lower part.

9. An electric motor according to claim 1 , wherein the electronics unit via at least one spring element is held in bearing contact on the operating panel and/or in bearing contact on the inner side of the electronics housing removable cover.

10. An electric motor according to claim 9 , wherein the at least one spring element is fastened on a covering which is arranged in the inside of the electronics housing and covers electronic components arranged in the electronics housing lower part, to the cover.

11. An electric motor according to claim 9 , wherein the at least one spring element is an elastomer element.

12. An electric motor according to claim 10 , wherein the elastomer element is designed as one piece with a seal which is arranged on the covering and which is preferably in sealingly bearing contact with the electronics housing lower part and the electronics housing removable cover.

13. An electric motor according to claim 1 , wherein the operating panel is arranged on an outer side of the electronics housing removable cover, and the electronics housing removable cover, below the operating panel, comprises at least one opening.

14. An electric motor according to claim 1 , wherein the operating panel on an operating panel surface, which is away from the electronics unit, comprises a closed cover film.

15. A pump assembly with an electric drive motor, wherein the electric drive motor is an electric motor comprising:
an electronics housing comprising an electronics housing lower part and an electronics housing removable cover; and
an operating unit comprising an operating panel fastened on the electronics housing removable cover, and the electronics housing removable cover with the operating panel is connectable to the electronics housing lower part of the electronics housing in at least two alternative alignments, wherein the operating panel is visible from a position outside of the electronics housing, the operating panel comprising a user interface, wherein the operating unit, apart from the operating panel, comprises an electronics unit which is arranged in the electronics housing lower part in a manner separated from the electronics housing removable cover and which cooperates with the operating panel.

16. A pump assembly according to claim 15 , further comprising:
a stator housing, the electronics housing lower part being connected to the stator housing, the electronics housing lower part and the electronics housing removable cover defining an interior space for one or more electronic components when the electronics housing removable cover is in contact with the electronics housing lower part, the stator housing comprising a stator housing interior space, wherein a stator and a rotor of the electric motor are arranged in the stator housing interior space, the electronics housing removable cover having an electronics housing outer surface, said electronics housing outer surface defining an operating panel recess, at least a portion of the operating panel being arranged in the operating panel recess, wherein interfaces of the electronics housing removable cover which come into contact with the electronics housing lower part are formed mirror-symmetrically to a middle line of the electronics housing removable cover.

17. An pump assembly according to claim 15 , wherein the operating panel is a purely mechanical component which is free of electric components.

18. An pump assembly according to claim 15 , wherein the electronics unit can be fastened in the electronics housing lower part in at least two alignments corresponding to the alternative alignments of the electronics housing removable cover.

19. An electric motor comprising:
an electronics housing comprising an electronics housing lower part and an electronics housing removable cover;
an operating unit comprising an operating panel fastened on the electronics housing removable cover, and the electronics housing removable cover with the operating panel is connectable to the electronics housing lower part of the electronics housing in at least two alternative alignments, the operating panel comprising user actuated operating elements, wherein the operating panel is visible from a position outside of the electronics housing; and
a stator housing, the electronics housing lower part being connected to the stator housing, the elect
