SIMOTICS 1LE0 series of 3 phase asynchronous motors is Totally Enclosed Fan Cooled (TEFC) with IP55 environmental protection, and applicable for general purpose use. These motors are designed and manufactured in accordance with ISO, IEC standards, GB standards. The 1LE0 series motor is designed for constant or adjustable speed with continuous duty operation (S1) over a speed range.
FEATURES OF SIEMENS 1LE0 SERIES
■ Frame material: grey cast iron or aluminum. ■ Standard color: stone grey (RAL 7030) ■ Rated power output: 0.55kW~315kW at 50Hz. ■ Available in 2, 4, 6 pole motor (0.75kW and up) with efficiency grade 3 or 2. according to GB18613-2012 and efficiency class IE2 or IE3 (50Hz) according to IEC 60034-30. ■ Optimized compact style construction. ■ Standard mounting construction according to IEC 60034-7: IM B3, IM B5, IM B35 and etc. ■ All motors are designed to IP55 degree of protection (IEC 60034-5) . ■ Re-greasing devices for FS1) 280 ~ 355 as standard, and for FS100 ~ 250 as option. ■ Reinforced bearings for increased cantilever forces for FS100 ~ 355 as option. ■ Winding protections with PTC, PT100 and KTY84-130 as option.
■Terminal box on top, and cable entry on right side (viewed from driven end). Varible location of connection boxes and cable entries as option.
■Insulation system is designed for temperature class 155 (F). At rated output with line-fed operation, the motors can be used in temperature class 130(B).
■Self ventilated motors with radial-flow fans (cooling method IC411 according to IEC 60034-6) as standard, forced air cool with external separately driven fans as option.
■FS 80~90 motor donot have eyebolt; FS 100~315 all motors have 2 eyebolts, and FS 355 motor have one eyebolt for transport.
1LE0 motors rated output powers means that the motor runs under continuous duty S1 (IEC 60034-1) operation when operated at ambient temperature from -20 ℃ to 40 ℃ and at altitudes of up to 1000 m over sea.
Voltage and Frequency
IEC 60034-1 differentiates between Category A (combination of voltage deviation ±5% and frequency deviation ±2%) and Category B (combination of voltage deviation ±10% and frenquency deviation +3% / -5%) for voltage and frequency fluctuations. The motors can supply their rated torque in both Category A and B. In Category A, the temperature rise is approximately 10 K higher than during normal operation.
+3% / -5%%
According to the standard, longer operation is not recommended for Category B.
Packing & Delivery
1020 (L) * 720 (W) * 770 (D)mm
The normal package is wooden box(Size: 1500*750*800). If export to european countries,the wooden box will be fumigated.If container is too tigher, we will use pe film for packing or pack it according to customers special request.
