Abstract
Die Motorbaueinheit ist für ein Tauchpumpenaggregat vorgesehen und weist einen Elektromotor (1) mit vorgeschaltetem Frequenzumrichter auf, die in einem gemeinsamen, im Querschnitt runden Gehäusemantel angeordnet sind. Der Frequenzumrichter ist als Einschub axial fluchtend zum Motor (1) angeordnet und besteht im Wesentlichen aus drei Bauteilen, nämlich einem den Leistungsteil beinhaltenden gemeinsamen Halbleiterbauelement (9), einem den Eingangs- und Zwischenkreis beinhaltenden Bauteil (14) und einem die Steuer- und Regelelektronik aufweisenden Bauteil (16). Das die Leistungselektronik beinhaltende Bauteil (8) ist über einen Wärmeverteiler (2) wärmeleitend mit dem Gehäusemantel verbunden. Der Wärmeverteiler (2) ist in seiner Außenkontur der Innenkontur des Gehäusemantels angepasst und in diesen zur Wärmeleitung über den gesamten Umfang eingepresst. The motor assembly is intended for a submersible pump unit and has an electric motor (1) with an upstream frequency converter, which are arranged in a common housing shell with a round cross section. The frequency converter is arranged as a slide-in unit axially aligned with the motor (1) and essentially consists of three components, namely a common semiconductor component (9) containing the power unit, a component (14) containing the input and intermediate circuit and one the control and regulating electronics having component (16). The component (8) containing the power electronics is connected to the housing jacket in a heat-conducting manner via a heat distributor (2). The outer contour of the heat distributor (2) is adapted to the inner contour of the housing shell and is pressed into the outer circumference for heat conduction.
