The heat sink is at least partially connected to the motor housing by calking or welding or screwing. A method is used for assembling a power unit having a motor housing for accommodating a motor, a heat sink and a drive electronics system, which is arranged on the heat sink, for the motor. A connection is established between the heat sink and the motor housing by calking or welding or screwing.
