Brand: SIEMENS
Specifications
SKU: Low-Voltage Motors 1LG0
Technical: The Siemens 1LG0 series refers to a line of robust, cast-iron, low-voltage, three-phase asynchronous motors designed for general industrial use, featuring IP55 protection, Class F insulation, and high energy efficiency (IE1/EFF2), suitable for applications like pumps, fans, and compressors needing constant or variable speed operation within a power range of 0.55kW to 315kW, known for their durable design and flexibility in terminal box orientation.
Key Features
Construction: Grey cast iron frame and terminal box.
Protection: Totally Enclosed Fan Cooled (TEFC) with IP55 degree of protection.
Insulation: Class F.
Efficiency: Meets IE1 (IEC 60034-30) and EFF2 (European) energy standards.
Power Range: 0.55 kW to 315 kW (at 50Hz).
Poles: Available in 2, 4, and 6-pole variants.
Voltage: Designed for multiple 3-phase mains supply voltages and frequencies (50Hz/60Hz).
Cooling: IC411 (self-ventilated).
Terminal Box: Rotatable (360 degrees) for flexible cable entry.
Bearings: V-ring seals standard on smaller frames (FS 80-132), oil seals standard on larger (FS 160+).
Duty: S1 (continuous duty) for constant or variable torque applications.
Applications
Pumps, fans, and compressors.
HVAC systems.
General industrial machinery requiring reliable, constant-speed or variable-speed drives.
