ABSTRACT:
An arrangement is disclosed for a motor controller, the arrangement including a number of power semiconductors and cooling elements, the cooling elements being connected to the power semiconductors for cooling them. The power semiconductors and the cooling elements are disposed around a center axis of the arrangement in such a manner that they demark a channel around the center axis from at least three sides, to which channel cooling surfaces of the cooling elements extend and in which the cooling medium is able to flow in the direction of the center axis, and the power semiconductors extend from the connections between the power semiconductors and the cooling elements substantially away from the center axis. The arrangement can further include at least one choke disposed in the channel demarked around the center axis.
