Siemens 1LE0 high-efficiency series motors are cast iron casing universal fully enclosed self fan cooled three-phase asynchronous motors with a protection grade of IP55. The design and production of LE0 series motors meet the requirements of relevant standards such as ISO, IEC, GB, and so on. Using the 1LE0 series motor, customers can save up to 10% energy consumption!

1LE0 series motors are suitable for continuous duty (S1), constant speed, or variable frequency speed regulation applications within a certain speed range.

Technical characteristics of Siemens 1LE0 series motors

■ Base and junction box material: gray cast iron;

■ Standard color: Stone Grey (RAL 7030);

■ The 2, 4, and 6 pole motors meet the energy efficiency level 2 of the GB18613-2006 standard, and can meet the IE2 efficiency level in the IEC 60034-30 standard;

■ Rated power: 0.55 kW~315 kW (50 Hz);

■ Optimized compact structure;

■ Standard installation structure types (in accordance with IEC 60034-7 standards): IM B3, IM B5, IM B35, etc;

■ The design protection level of all motors is IP55 (IEC 60034-5);

■ FS 280~355 is equipped with a standard relubrication device, with FS 100~250 as an option;

■ For FS100 to 355 range motors, an enhanced cantilever force design is optional;

■ Motors can choose PTC or PT100 thermistors or KTY84-130 for winding protection

■ The standard position of the junction box is on the top of the base, and the incoming hole is on the right side (viewed from the drive end). The junction box position and incoming direction in the options can be changed;

■ The insulation system is used at 155 (F) temperature level and 130 (B) temperature level for rated output and direct power supply;

■ The standard cooling method of the motor is self fan cooling (IC 411 specified in IEC 60034-6), which can provide independent drive fan forced cooling;

■ FS 80 to 90 motors do not have lifting lugs; FS 100~315 motors have two lifting rings, and FS 355 motors have one lifting ring for transportation.
