An apparatus comprises a power module (1) and an electric machine (e.g. a multiphase motor of a vehicle), wherein the power module (1) comprises a plurality of components (4) attached to a circuit layer (5) and wherein the power module (1) and the electric machine (e.g. its end bearing plate (2)) are physically connected by an isolation layer (7), the isolation layer (7) electrically insulating the power module (1) and the circuit layer (5) from the electric machine. The power module (1) is thus an integral part of the electric machine. The circuit layer (5) may be a lead frame. The plurality of components (4) may be attached to the circuit layer (5) by sintering or soldering. The isolation layer (7) may be an epoxy resin filled with thermally conductive fillers. An encapsulation layer may be provided, by filling a resin (12) within additional resin walls (dam) (11). A multi-terminal socket (15) with a plurality of terminals (13) mounted in a plastic holder (14) may be provided, configured perpendicular to the circuit layer (5).
