The 1LA7 and 1LE1 modular 2- and 4-pole motors operate in a power range from 0.37 kW to 7.5 kW and are designed to meet the requirement for reduced energy consumption in hydraulic drive systems across a wide range of industrial sectors. Built to IEC compliant sizes, the EMC-optimized housing design of these motors combines maximum flexibility with minimal installation costs, allowing for the addition of optional components such as encoders, brakes, thermistors, and fans for easy customization to customer requirements. Junction boxes, integrated bolts, and reinforced bearing plates further enhance functionality. A screw-mount base is also available, particularly useful for installation in confined spaces.
The rotors of the 1LA7 and 1LE1 are manufactured using innovative technology with a composite of highly conductive materials, allowing for a considerable reduction in the size and weight of the motors. Both models are designed to meet IE1 (standard), IE2 (high), and IE3 (premium) efficiency standards, without any increase in shaft height across the entire range, enabling the motors to be replaced using existing mechanical infrastructure at minimal cost
The high quality of Siemens' motor insulation system guarantees maximum electrical and dynamic resistance, allowing all Siemens motors with variable speed drives up to 460 V to operate directly or via a converter, without the need for additional measures.
The 1LA7 and 1LE1 energy-efficient AC induction motors are suitable for a wide range of industrial applications, including pumps, fans, conveyor belts, and compressors. More robust models are also available, ideal for use in harsh environments such as those found in the chemical and petrochemical industries.
The 1LA7 and 1LE1 three-phase AC induction motors are available at rsonline.es with delivery in 24/48 hours.
