<strong>SIMOVERT</strong> <strong>MV</strong>6SE80 Drive ConvertersDesignAir-cooled drive converters for 6.0 kV and 6.6 kV (continued)This has the followingbenefits:Retrofit applicationsExisting fixed speed mo<strong>to</strong>rsturn <strong>to</strong> variable-speed driveswhen converters are added:¦ The existing mo<strong>to</strong>r is suitablefor converter-fed operationwithout derating, because there is no additional loss inthe mo<strong>to</strong>r.¦ No mechanical changeoverat the driven machine isnecessary, e.g. adjustment ofthe shaft height, of thefoundation, of the coupling,the cooling system etc.¦ The existing mo<strong>to</strong>r cablesare preserved; no changesnecessary.¦ No supplementary outputchokes are necessary with long mo<strong>to</strong>r cables.New configurationsFig. 3/3Output voltage and current of the 6.0 and 6.6 kV <strong>SIMOVERT</strong> <strong>MV</strong> drive converter¦ Standard medium-voltagedrives can be put <strong>to</strong> usewithout extra measures andwithout derating.¦ It is possible <strong>to</strong> use standardpower cables for connectingthe mo<strong>to</strong>r.¦ No supplementary outputchokes are necessary withlong mo<strong>to</strong>r cables.Please refer <strong>to</strong> the notes onPage 6/13 for configuration of6.0kV/6.6kV drives.3Siemens DA 63 · 2004 3/5
