Abstract
The present invention relates to an electric motor comprising an attached additional element, in particular an incremental shaft encoder, and a mounting base plate which has seated thereon the additional element and is connected to the electric motor such that its angular position is adjustable during assembly. The adjustability of the angular position is to be improved, whereby mounting is simplified. To this end, a profile toothing is provided on the electric motor and a counter-profile toothing on the mounting base plate, the toothings engaging each other in a substantially accurately fitting manner, thereby permitting a mounting of the base plate in different angular positions in angular steps which are predetermined by the tooth pitch.
Claims19
An electric motor apparatus, comprising in combination an electric motor having a motor housing, a mounting base plate (4) connected to said motor housing (2), an additional element seated on said mounting base plate, a profile toothing (26) provided on said motor housing (2), and a counter-profile toothing (8, 9) provided on said mounting base plate (4), said profile and counter-profile toothings engaging each other in a substantially accurate fitting manner, said profile toothing (26) and counter-profile toothing (8, 9) permitting the mounting of said mounting base plate (4) in different angular steps which are predetermined by the tooth pitch.
An electric motor apparatus, comprising in combination an electric motor having a motor housing, a mounting base plate (4) connected to said motor housing (2), an additional element seated on said mounting base plate, a profile toothing (26) provided in a cylindrical receiving opening of said motor housing (2), and a counter-profile toothing (8, 9) provided on said mounting base plate (4), said profile and counter-profile toothings engaging each other in a substantially accurate fitting manner, said profile toothing (26) and counter-profile toothing (8, 9), in combination with a pair of spring arms jointly defining said cylindrical receiving opening (7) of said mounting base plate (4), permitting the adjustable mounting of said mounting base plate (4) in different angular steps which are predetermined by the tooth pitch.
