Product Overview
SEW RM97 DRN100L4: High-Performance Helical Gearmotor for Agitator & Conveyor Drive Systems
The SEW RM97 DRN100L4 is a robust in-line helical gearmotor specifically engineered for applications requiring high overhung loads and high axial forces. Featuring an extended bearing housing (typical of the RM series), this 3.0 kW unit is the industry standard for industrial mixers, agitators, and heavy-material handling systems.
Driven by the DRN100L4 IE3 premium efficiency motor, the RM97 delivers an optimal balance between torque density and energy economy. Its coaxial design ensures a streamlined power flow, while the precision-ground helical gears provide quiet operation and long-term durability in continuous-duty (S1) environments. Whether integrated into a new automated line or used as a direct replacement in existing SEW-EURODRIVE setups, the RM97 offers unparalleled structural rigidity.

Key Features
- Agitator-Specific Design: Unlike the standard R-series, the RM97 features a reinforced output shaft and bearing arrangement, specifically designed to absorb the heavy radial forces common in mixing and stirring processes.
- IE3 Energy Compliance: The integrated DRN100L4 motor meets global "Premium Efficiency" standards, significantly reducing total cost of ownership (TCO) by lowering power consumption during 24/7 operations.
- Vibration Damping Housing: The high-grade cast iron casing is designed to minimize resonance, protecting the gear teeth and bearings from premature wear during shock loads.
- Global Interchangeability: Full compliance with IEC and CE standards means the RM97 is ready for international export, with spare parts and service support available in nearly every industrial market.
Industrial Applications
The SEW RM97 DRN100L4 is engineered for environments where standard inline reducers might fail due to excessive axial or radial stress. Its unique reinforced bearing design makes it the preferred drive for:
- Heavy-Duty Agitators & Mixers: Specifically designed for the chemical and food processing industries. The RM97 handles the high bending moments exerted by long agitator shafts during the mixing of high-viscosity liquids or solids.
- Wastewater Treatment Systems: Ideal for water aerators and flocculators that require continuous 24/7 torque output. The IP55-rated DRN100L4 motor ensures stable performance in humid, demanding outdoor conditions.
- Large-Scale Belt Conveyors: In mining and bulk material handling, the 3.0 kW output and high service factor of the RM97 allow it to manage the high starting torque and shock loads of fully loaded conveyor belts.
- Automated Palletizers: The precision-ground helical gears provide the smooth, vibration-free motion necessary for robotic palletizing and high-speed sorting lines in logistics centers.
FAQ
FAQ
Q: Q1: What makes the RM97 different from a standard R97 gearbox?
A: A: The RM97 is specifically designed with an extended bearing hub and reinforced output bearings. This makes it suitable for applications like agitators where the shaft is subject to high bending moments and axial thrust, which might exceed the capacity of a standard R97.
Q: Q2: Can this unit be mounted vertically?
A: A: Yes, the RM97 supports multiple mounting positions, including vertical (M2/M4). For vertical installations, we ensure the correct oil level and high-performance sealing (such as FKM oil seals) are used to prevent leakage and ensure proper lubrication of the top bearing.
Q: Q3: Is the DRN100L4 motor compatible with frequency inverters?
A: A: Absolutely. The DRN series is designed for inverter operation. For applications requiring a wide speed range or very low speeds, we can also provide an optional forced cooling fan (VR) to maintain thermal stability.
Q: Q4: How do I select the correct gear ratio for my conveyor?
A: A: Our technical team can help you calculate the required output speed and torque based on your motor's 1455 RPM base speed. We offer a wide range of standard ratios to match your specific linear speed requirements.
