Modular Options & Accessories (System Enhancement)
Given the high power output of 15kW, the R107 can be enhanced with specialized accessories for predictive maintenance and safety.
1. High-Performance Braking (BE Series)
The BE20 or BE30 spring-applied brake is recommended for the DRN160L4 motor. It provides massive holding torque, ensuring that heavy loads are secured instantly during power loss or emergency stops.
2. Feedback & Motion Control
For synchronized systems, the R107 can be equipped with:
EG7S / EH7S Encoders: High-resolution feedback for precise speed and position control via VFD.
EI7C Encoders: Compact, cost-effective speed sensing.
3. Advanced Diagnostic Tools
DUO (Diagnostic Unit Oil): Monitors the lubricant's water content and temperature. For the R107, which requires large oil volumes, this prevents unnecessary oil changes while protecting the gears.
DUV (Diagnostic Unit Vibration): Essential for detecting early bearing wear or gear misalignment in high-power drives.
Built for Heavy Industrial Infrastructure
The R107 series is a staple in sectors where downtime translates to massive financial loss.
- Mining & Minerals: Driving Primary Belt Conveyors, Heavy Feeders, and Ball Mill Auxiliary Drives. The 70mm shaft handles high chain and belt tensions effortlessly.
- Construction & Aggregates: Reliable power for Large Concrete Batching Plants, Asphalt Mixers, and Stone Crushers.
- Water & Waste Management: Powering Large-scale Screw Pumps, Aeration Bridges, and Sludge Centrifuges in municipal plants.
- Metals & Recycling: Heavy-duty drive for Steel Roller Tables, Scrap Shredders, and Large Baling Presses.
FAQ
Q: When should I choose the R107 over the R97 for 15kW?
A: While the R97 can technically be paired with a 15kW motor, it is limited to 3000 Nm. The R107 provides 4300 Nm. If your application involves high starting torque or shock loads, the R107 offers a much safer Service Factor (fb), ensuring the internal gears and bearings do not fatigue prematurely.
Q: What are the lubrication requirements for a 15kW drive?
A: Due to the high power and torque, heat dissipation is critical. We recommend Synthetic CLP PG (Polyglycol) oil for the R107. This extends oil life significantly and reduces friction, which can lower the operating temperature of the gearbox by up to 10°C compared to mineral oil.
Q: Is the DRN160L4 motor suitable for 60Hz operation (e.g., USA/Brazil)?
A: Yes. The DRN series is a global motor. At 60Hz, the power of the 15kW motor increases to approximately 18 kW (24 HP), and the rated speed increases from 1470 RPM to 1770 RPM. Ensure your gearbox ratio is selected based on the final output speed at 60Hz.
