Abstract: An electrical module and a circuit board arrangement including an electrical module are disclosed. The electrical module includes an upper side and an underside, the upper side having four rectangularly arranged side edges, an electrical component embedded in the electrical module, and at least three electrical solder pads formed on the upper side configured to make electrical contact with the electrical component and configured to come into contact with an associated electrical solder pad of a circuit board via a solder layer. The solder pads of the electrical module are arranged in a symmetrical arrangement on the upper side of the electrical module, and/or the solder pads are arranged axially symmetrically on the upper side of the electrical module, and/or the solder pads extend along two opposite side edges on the upper side of the electrical module.

Abstract: The disclosure relates to an electric drive unit that includes: a motor housing that surrounds an electric motor and has an external side; cooling fins configured on the external side of the motor housing; and an electrical module having components to be cooled. The electrical module is disposed in or on an additional housing that adjoins the motor housing, wherein the additional housing on the external side thereof has cooling fins that run in the same direction as the cooling fins of the motor housing.

Abstract: An electric drive unit includes a three-phase motor having a rotor, a stator, and a motor housing, wherein the stator has three coil windings that each include one winding wire having two coil connectors. The electric drive unit further includes a converter that provides the three-phase motor with a three-phase alternating current and has three terminal contacts. The coil connectors are connected to the terminal contacts by way of a star circuit or a delta circuit. The converter is implemented in a circuit board assembly having at least one circuit board. The terminal contacts of the converter are on the circuit board, and the connections, provided in the context of the star circuit or delta circuit, between the coil connectors and the terminal contacts of the converter, are implemented in that the respective ends of the winding wires of the coil windings are connected directly to the circuit board.
