Embodiment Construction

[0023] figure 1 The stator body 1 of the electric machine 2 according to the first exemplary embodiment of the invention is shown schematically. The electric machine 2 can be used in particular as the electric machine 2 of a device for adjusting components of a motor vehicle. In particular, the electric motor 2 can be designed as a brushless DC motor. For example, electric motor 2 can be used for auxiliary and comfort equipment of a motor vehicle. Possible areas of use are, for example, sliding sunroof drives, seat adjustments, window regulators, wiper drives, transmissions and clutch regulators, electric steering, anti-lock brakes, oil pumps, gasoline pumps and Water pumps, valve regulators and other servo drives. However, the electric machine 2 is also suitable for other applications.

[0024] The stator body 1 has a plurality of laminations 3 , 4 , 5 , 6 , 7 , 8 , 9 . Here, for simplified illustration, only laminations 3 to 9 are marked. The stator body 1 is formed in...

Abstract

The invention relates to an electric machine which is used, in particular, as an electric motor for devices used to displace elements of a motor vehicle, comprising a housing part (25) and at least one stator body (1) which is arranged in said housing part (25). Said stator body (1) comprises on an outer side (15) or the housing part (25) on an inner side (28), at least one recess (18, 35, 36). The inner side (28) of the housing part (25) faces towards the outer side (15) of the stator body (1). Said stator body (1) is joined to the housing part (25) by means of an adhesive (26), said adhesive (26) extending from the recess (18, 35, 36) into an assembly gap (29) formed between the outer side (15) of the stator body (1) and the inner side (28) of the housing part (25). As a result, a highly stable connection between the stator body (1) and the housing part (25) is established. Shavings can also be prevented from being formed during connection.

Description

technical field [0001] The invention relates to an electric motor, in particular for adjusting components of a motor vehicle, and to a method for producing a connection between a stator body and a housing part. In particular, the invention relates to the field of electric motors for auxiliary and comfort equipment in motor vehicles, such as sliding sunroof drives, seat adjustments, electric window regulators, wiper drives, transmissions and clutch adjustments. Electric power steering, anti-lock braking systems, oil pumps, gasoline pumps and water pumps, valve regulators and other servo drives. Background technique [0002] A method for producing a fixed connection between a hollow cylinder and an inner cylinder surrounded by the hollow cylinder is known from DE 103 32 958 A1. In this case, the inner cylinder is formed from a plurality of profile laminations which lie adjacent to one another in the axial direction and form a cylindrical lamination pack. In order to obtain a...
