Abstract
A rotary electric machine, in particular an electric motor, has a winding, an electronic control device, and an electrically conductive shielding plate arranged between the control device and the winding. A connection device which includes at least one coupling element for electrically connecting the control device to one or more lines and a mass element provided for connecting to an electric mass potential. In order to improve the machine with respect to electromagnetic interference, the shielding plate is electrically conductively connected to the mass element by way of a sheet metal tongue via a first electric pressure-contact.
