Abstract
A rotary electric machine having a stator and a rotor, in addition to an electric control device and a connection device which comprises at least one coupling element for electrically connecting the control device to one or several electrical lines and a mass element provided to connect to an electric mass potential. In order to improve the machine with respect to electromagnetic interference, the stator is connected to the mass element by a contact bridge which has a first securing section and a second securing section in addition to a bridge element arranged between the securing sections and includes a single-piece spring steel sheet which is at least partially sinuous.
Claims7
A rotary electric machine comprising:
- a stator;
- a rotor;
- an electrical control device;
- a connector, which has at least one coupling element for electrically connecting the control device to one or more electrical lines;
- and
- a ground element connected to an electrical ground potential,
- wherein the stator is connected to the ground element via a contact bridge that comprises a first securing section, a second securing section, a bridge element arranged between the first securing section and second securing section, the bridge element being a single-piece spring sheet formed at least partially meander-shaped, and
- wherein at least one of the first securing section or the second securing section have a continuous clamping opening,
- wherein a clamping pin is adapted to be clamped in the continuous clamping opening, and
- wherein the continuous clamping opening is a straight clamping slot, wherein at both ends of the clamping slot, in each case, at least one separation slot connected to the clamping slot is provided, and wherein, in each case, a bendable edge strip is formed between the separation slots.
