The Siemens 1LG6317-4AA96-Z is a high-power 4-pole AC induction motor from the 1LG6 series with a 315L large frame size, delivering 185 kW (approximately 248 HP) at 400V/50Hz. As an IE3 Premium Efficiency motor, it meets the highest efficiency standards for industrial low-voltage applications. The motor features IP55 protection, IC411 self-ventilated cooling, IM B3 foot-mounted construction, and a nominal operating speed of approximately 1485-1490 rpm. With a weight of approximately 1200-1350 kg and excellent starting characteristics (starting torque ~1.9-2.2x rated, starting current ~6.5-7.5x rated), this motor is ideal for heavy-duty applications including large pumps, compressors, fans, crushers, and industrial processing equipment. The "-Z" suffix denotes factory-special options, requiring reference to the original order documentation for full specification details.
FAQ
Q: What is the rated power of the Siemens 1LG6317-4AA96-Z motor?
A: The rated power is 185 kW (approximately 248 HP) at 400V/50Hz in 4-pole configuration.
Q: What does the "Z" suffix mean in 1LG6317-4AA96-Z?
A: The "-Z" indicates factory-special options that deviate from the standard catalog motor. These could include specific bearing arrangements, different voltage/frequency settings, special sealing, or specific terminal box locations. Consult the original order confirmation or motor nameplate for exact details.
Q: What are the physical dimensions of this 315L frame motor?
A: It has a 315mm shaft height, approximately 610mm x 500mm footprint, 90mm shaft diameter x 170mm shaft length, and weighs approximately 1200-1350 kg.
Q: What is the efficiency class of this motor?
A: IE3 (Premium Efficiency), which is standard for the 1LG6 series motors produced after 2015.
Q: Is this motor suitable for VFD operation?
A: Yes, with Class F insulation and IC411 cooling. For VFD applications, verify that the "-Z" factory special options include provisions for bearing currents (insulated bearings) at low speed operation.
Q: What is the starting current and torque?
A: Starting current is approximately 6.5-7.5 times rated current, and starting torque is approximately 1.9-2.2 times rated torque.
Q: What is the protection rating?
A: IP55 — dust-tight and protected against water jets, suitable for most industrial environments.
Q: Can this motor operate at 60Hz?
A: The 1LG6 series is often compatible with 60Hz operation. Check the physical nameplate for the specific 60Hz voltage and power ratings.
