1SIMOVERT MVOverviewApplicationsSIMOVERT MV drive converters and H-compact, H-compact PLUS high-voltage motors:Optimally harmonized with one anotherThe SIMOVERT MV drive The self-ventilated, rib-cooledconverters together with the motors H-compact (1LA4) arewell-proven H-compact and available in an output rangeH-compact PLUS high-voltage from 0.8 MW to 3.6 MW. Theymotors form a high-performancedrive package over a applications where highoffer significant advantages forwide output and speed range. torques are demanded even atDuring development, the drive low speeds. If the requirementsconverter and motor were alwaysconsidered as a single en-the force-ventilated versionare even more stringent, thentity, and were harmonized with (1PQ4) provides torques whichone another both from the perspectiveof cost-effectiveness rated motor torque over a wideare almost the same as theas well as technically. This is the speed control range.reason why a filter is not requiredbetween the drive converterand the motor. The motorsare extremely rugged,which means that they can besimply operated under even thetoughest application conditions.H-compact PLUS high-voltagemotors (shaft height from450 mm to 630 mm) cover anoutput range from 0.7 MW to7 MW. The motors have a modulardesign and are availablewith three cooling types:¦ open-circuit cooling (1RA4),¦ air-to-water cooling (1RN4)and¦ air-to-air cooling (1RQ4).As a result of this variable coolingconcept, the drives can beintegrated into any plant orsystem configuration.The motors are characterizedby superb output, reliability andefficiency. This is mainlyachieved as follows:¦ Excellent operating data,expecially when it comes toefficiency and power factor¦ High power density¦ Compact type ofconstruction¦ Stiff rugged enclosure andbearing endshields manufacturedout of cast iron¦ All parts are providedwith long-term corrosionprotection¦ MICALASTIC high voltageinsulation using VPItechnology (VacuumPressure Impregnation)1/4 Siemens DA 63 · 2004
