摘要:
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.

The present invention relates to a control device for a radiator fan, in particular for a radiator fan of a motor vehicle, having an external control device which is designed to generate a controlled variable for an electric motor of the radiator fan according to a first predefined setpoint value, and having an internal control device which is designed to control the motor current of the electric motor of the radiator fan according to a predefined first motor current maximum value if the controlled variable which is generated by the external control device assumes such a value that the motor current exceeds the predefined first motor current maximum value. The present invention also relates to a radiator fan arrangement and to a method for controlling a radiator fan.

摘要:
An electric motor for driving a motor vehicle component, particularly a fan wheel for cooling coolant water, contains a rotor that is rotatably mounted opposite a stator, and an electronic system. The electronic system contains a punched grid provided with a plastic over-mold and a current path which conducts the motor current and has two current path ends spaced apart from one another forming an interruption point that is bridged by a thermal fuse. The thermal fuse has a spring-loaded contact bridge which is held so as to pivot about an axis that extends perpendicularly to the plane in which the interruption point lies.
