An electric motor with a heat source is arranged on a shaft in a co-rotating manner, wherein a first and a second cooling fin arrangement interact in order to dissipate heat from the heat source to the outside.

A circuit board to be mounted in a non-drive end shield of an electric motor has a converter formed on the circuit board. The circuit board is divided into a central region and a number of toothed regions surrounding the central region, wherein planes of the toothed regions are bent with respect to a plane of the central region in a mounting position.

A motor system includes a stator, a rotor, a number of power modules which each have planar contact faces for dissipating heat, a control device which is designed to actuate the power modules, a housing, wherein the stator and the rotor are arranged inside the housing, and at least one heat sink. The heat sink has a number of planar contact faces which are connected in a thermally conductive fashion to respectively corresponding contact faces of the power modules. The heat sink has regions for dissipating heat, wherein a coolant flows around the regions in order to dissipate heat.
