1LE1002-1AB42-2AA4 — Siemens SIMOTICS GP 1LE1 IE3 Premium Efficiency Motor
The Siemens SIMOTICS GP 1LE1 is the general-purpose IE3 premium efficiency induction motor forming the mechanical drivetrain of the vast majority of new industrial installations in Saudi Arabia, from fractional kilowatt auxiliary pumps through to 315 kW main process motors at the Kingdom's largest petrochemical and water infrastructure facilities. Built with a cast iron frame, IP55 sealing, Class F insulation with Class B temperature rise (providing a 25°C thermal headroom margin), and pre-greased sealed bearings for extended regreasing intervals, the 1LE1 is engineered for reliable continuous operation in Saudi Arabia's demanding ambient conditions — including the 45–50°C summer temperatures that reduce motor thermal margin and stress insulation systems in outdoor applications.
The 1LE1's IE3 premium efficiency rating delivers energy consumption reductions of 1–3% versus IE2 motors — a modest percentage translating to significant absolute savings across thousands of motors in a Saudi petrochemical facility's motor inventory. At 90 kW, the IE2 to IE3 difference is approximately 450 W continuous; across a facility with 500 similar motors, that is over 2 GWh annual savings. Saudi Arabia's Energy Efficiency Program (SEEP) mandates IE3 for new motor installations above 0.75 kW in most industrial applications, making the 1LE1 the compliant standard specification. The converter-duty (CD) variant incorporates reinforced winding insulation for VFD dV/dt voltage spikes, an external fan for cooling at low speeds, and insulated bearings to prevent shaft current damage — required by ARAMCO Engineering Standards for all motor-drive packages.
Razz Middle East supplies SIMOTICS GP 1LE1 IE3 motors in all IEC frame sizes from IEC 80 through IEC 315 and standard mounting configurations (B3, B5, B35, V1) for immediate delivery throughout Saudi Arabia, with motor-drive package sizing support for SINAMICS G120 and G150 applications.

Key Features & Benefits
- IE3 premium efficiency class per IEC 60034-30-1 reduces motor energy consumption by 1–3% versus IE2, meeting Saudi Energy Efficiency Program (SEEP) IE3 minimum efficiency requirements for new industrial motor installations.
- Class F insulation with Class B temperature rise provides a 25°C thermal headroom margin, extending insulation life and providing additional protection against intermittent overloading in high-ambient Saudi environments.
- IP55 ingress protection seals motor internals against dust and water jets, enabling outdoor installation at pump stations and process areas across Saudi Arabia without additional housing.
- High-ambient-temperature variant rated up to +60°C maintains full rated output in outdoor Saudi summer conditions where standard motors require derating.
- Converter-duty (CD) variant with reinforced winding insulation, external cooling fan, and insulated bearings is optimised for SINAMICS G120/G150 VFD operation — required by ARAMCO Engineering Standards for all motor-drive packages.
- Pre-greased sealed bearings in IEC 80–180 frames provide maintenance-free bearing operation for up to 20,000 hours, reducing maintenance on continuously-operating motor installations.
- IEC standard frame dimensions ensure mechanical interchangeability with motors from other manufacturers, allowing 1LE1 to directly replace competitor motors without baseplate or coupling modifications.
Industrial Applications in Saudi Arabia
- Centrifugal pump drives at NWC water pumping stations, SWCC desalination facilities, and ARAMCO utility water systems, where IE3 efficiency and IP55 sealing satisfy SEEP requirements and outdoor installation conditions.
- HVAC air handling unit, cooling tower, and chilled water pump motor drives in commercial buildings and industrial facilities, where IE3 reduces facility energy consumption and satisfies SEC large-consumer reporting.
- Conveyor and material handling system motors at cement plants and quarrying operations, where cast iron frame robustness and IP55 sealing provide reliable performance in dusty outdoor environments.
- SINAMICS G120-driven motor-drive packages at SABIC and ARAMCO process facilities, where converter-duty 1LE1 motors satisfy ARAMCO Engineering Standards for VFD-connected motors.
- Fan drives in industrial ventilation, HVAC, and process cooling, where the high-ambient rating maintains full airflow delivery during Saudi Arabia's 45–50°C summer peak demand periods.
- Compressor motor drives at industrial utility systems, where the 1LE1's cast iron frame and Class F insulation withstand continuous heavy-duty operation cycles.
- Irrigation and agricultural pump drives in Qassim, Al-Ahsa, and Tabuk regions, where IE3 efficiency reduces energy costs at high-running-hour sites.
