1LE1

The Siemens 1LE1 refers to a range of SIMOTICS GP and SD low-voltage motors. These are highly efficient, compact, and robust motors designed for a variety of industrial applications. Here’s a detailed breakdown of the Siemens 1LE1 series:

The Siemens 1LE1 motor series is part of the SIMOTICS GP (General Purpose) and SD (Severe Duty) low-voltage motors. They are known for their high efficiency, with some models reaching the IE4 energy efficiency class, which is currently the highest available globally.

These motors are used for standard drive tasks in industrial environments. The GP series, with aluminum housing, is particularly suited for pumps, fans, compressors, conveyor belts, and lifting equipment. The SD series, with cast iron housing, is designed for harsh environments and can be used in applications like extruders, mixers, and in the petrochemical industry.

Design Features of 1LE1

Energy Efficiency: The 1LE1 motors are among the most compact and efficient on the market, with some reaching IE4 energy efficiency levels;
Housing: The GP series features an aluminum housing, while the SD series has a cast iron housing for severe duty applications;
Cooling: Optimized cooling designs ensure that the motors can handle standard drive tasks effectively;
Variety: The series includes a wide range of power outputs and sizes to suit different industrial needs.

The 1LE1 motors are versatile and can be used across various industries, including manufacturing, processing, petrochemicals, and anywhere robust and efficient motor solutions are required. They are particularly beneficial in environments where energy efficiency and reliability are paramount.
