An electric motor, in particular a radiator fan motor of a motor vehicle, has a stator which is fitted with a rotating-field winding, and a rotor which is mounted such that it can rotate in relation to the stator. A converter electronics system is provided, wherein a number of contact elements for insulation-free or enamel-insulated connection contacts of at least one component of the converter electronics system and/or for enamel-insulated winding ends of the rotating-field winding are mounted on a printed circuit board. The contact elements are in the form of clamping contacts or insulation-displacement terminal contacts.
