1LG0207-2AA60-Z — Siemens SIMOTICS GP 1LG0 Low-Voltage Induction Motor
The Siemens SIMOTICS GP 1LG0 is a large-frame cast iron low-voltage squirrel-cage induction motor covering 75 kW to 1000 kW at 380–690 V, representing the workhorse of heavy industrial applications where durability, efficiency, and repairability are paramount. The 1LG0 is designed to IEC frame sizes 315 to 500 with TEFC (IC411) cooling, Class F insulation rated to 155°C, and IP55 protection, providing reliable operation in the harshest industrial environments found in Saudi Arabia's oil & gas, petrochemical, mining, and water sectors. IE2 and IE3 efficiency classes are available, with IE3 becoming the regulatory baseline for motors above 0.75 kW under the Kingdom's expanding energy efficiency standards aligned with global IEC 60034-30-1 requirements.
The 1LG0 is available in converter-duty variants with reinforced insulation system (800 V peak voltage withstand) and optional shaft grounding ring to prevent bearing current damage when driven from variable frequency drives — a critical specification for Saudi Arabia's process plants where most large motors are VFD-driven. Optional PT100 resistance thermometers embedded in each phase winding and in both bearing housings provide continuous temperature monitoring via the plant DCS, while optional space heaters prevent condensation during extended standby periods in the Kingdom's coastal humid environments near Jeddah and Yanbu. Anti-condensation drain holes and tropical insulation options address the high ambient humidity common in coastal Saudi industrial facilities.
In Saudi Arabia, the SIMOTICS GP 1LG0 motor KSA is the standard specification for large pump and fan drives at SWCC desalination plants, SABIC and Aramco petrochemical cooling water systems, and cement plant raw mill and kiln fan drives operated by Saudi Cement, YACCO, and Al Jouf Cement. Its cast iron frame provides the structural rigidity required for direct coupling to multi-stage centrifugal pumps on concrete or fabricated steel baseplates at high-vibration sites. Hadeed steel rolling mill auxiliary drives in Jubail rely on the 1LG0's thermal design for continuous duty at elevated ambient temperatures exceeding 45°C.
Razz Middle East supplies SIMOTICS GP 1LG0 motors in standard and special configurations, including ATEX Zone 2 Group IIA/IIB options for classified areas, with full IEC test certificates, motor data sheets, and dimensional drawings. We support 4-hour RFQ response and rapid delivery to all major Saudi industrial cities.

Key Features & Benefits
- IE3 premium efficiency class reduces motor losses by up to 20% versus IE1 baseline, delivering significant energy cost savings on Saudi Arabia's high-tariff industrial electricity supply across 8,000+ annual run hours.
- Converter-duty reinforced insulation system withstands 800 V peak inverter output voltage and includes optional shaft grounding ring to prevent electrostatic bearing current damage — essential for VFD-driven motors at process plants.
- Cast iron frame IEC 315–500 provides the rigidity and damping required for direct coupling to multi-stage centrifugal pumps and large industrial fans on concrete baseplates subject to vibration from cavitation and unbalanced loads.
- PT100 resistance thermometers embedded in each stator phase winding and both bearing housings enable continuous thermal monitoring via SCADA, providing early warning of winding or bearing deterioration before catastrophic failure.
- Optional space heaters (standard on tropical variants) prevent winding condensation during extended standby periods in Saudi Arabia's coastal industrial areas near Jeddah, Al Khobar, and Yanbu where ambient humidity regularly exceeds 80% RH.
- ATEX Zone 2 Group IIA/IIB Ex ec (increased safety) configuration available for classified hydrocarbon areas at Aramco and SABIC facilities, meeting the explosion protection requirements of IEC 60079-7.
- Rewindable design with accessible terminal box and standard IEC dimensions allows in-kingdom repair at certified motor rewind shops, reducing total lifetime cost and avoiding long lead times for replacement units.
Industrial Applications in Saudi Arabia
- High-pressure seawater reverse osmosis pump drives at SWCC and MARAFIQ desalination facilities along the Red Sea and Arabian Gulf coasts, where IE3 efficiency on continuous-duty 500–1000 kW motors generates millions of SAR annual energy savings.
- Cooling water and process pump drives at SABIC petrochemical complexes in Jubail Industrial City, where converter-duty insulation and shaft grounding rings prevent bearing failures on VFD-controlled large centrifugal pumps.
- Raw mill fan and kiln ID fan drives at Saudi Cement, YACCO, and Al Jouf Cement plants, where the cast iron frame withstands high-vibration loading from induced draught fan aerodynamic forces at full load.
- Seawater intake and circulating water pump drives at Ras Al-Khair and Yanbu power generation and industrial complexes, where continuous duty in high ambient temperatures demands Class F insulation and effective TEFC cooling.
- Hadeed and downstream steel industry rolling mill auxiliary drives in Jubail, where the 1LG0's robust construction handles the demanding duty cycle of descaler pumps, roller table drives, and coiler auxiliary systems.
- Aramco gas compression and water injection pump drives in the Eastern Province, where ATEX Zone 2 certification allows safe motor installation in classified areas adjacent to hydrocarbon processing equipment.
- Municipal sewage and wastewater pump drives at treatment plants operated by NWC across Saudi Arabia, where the motor's IP55 rating and anti-corrosion shaft and hardware options handle the aggressive wastewater environment.
