Motor power axial penetrator with sealings for integrated motor machine

Abstract

Traditionally, integrated motor compressors utilize a radial penetrator that is connected to the motor stator via terminals and wires. This radial connection requires the motor stator to be installed within the compressor housing prior to the connection. In addition, the wires are subject to failure from rapid gas decompression. Accordingly, an axial penetrator is disclosed to provide a conductive path, through the housing, parallel to the longitudinal axis of an integrated motor machine (e.g., integrated motor compressor). This enables the connection to be performed prior to installation of the motor stator within the housing. This also enables the conductive path between the motor windings and axial penetrator to be formed, as a single integrated path, using the same conductive and insulative materials. In turn, this ensures that the entire conductive path behaves the same during decompression, reduces costs, simplifies the installation process, and increases the robustness of the connection.
