1. Key Specifications

2. Technical & Performance Features

Power & Speed

• Rated Power: 0.37 kW (ideal for light-duty applications)
• Motor Speed (50Hz, 4-Pole): 1500 rpm (standard synchronous speed)
• Output Speed:
  $\text{Output Speed}=\genfrac{}{}{0ex}{}{1500}{18}\approx 83\text{rpm}$ (due to gear ratio)
• Frequency: 60 Hz (optimized for North American and other 60Hz markets)

Gearbox

• Gear Ratio (i = n₁/n₂): 18:1 (provides high torque reduction with minimal space requirements)
• Type: Helical-Worm (combines helical gears for smoothness and worm gears for self-locking capabilities)

Electrical

• Voltage: 220-230VΔ / 380-400VY (dual-voltage capability for flexible star-delta starting)
• AC/DC: AC (standard alternating current operation)
• Energy Efficiency: Not Applicable (likely due to older IE1/EFF2 standards; newer models may offer IE2/IE3)
• Brake: No Brake (external braking solutions may be required for stopping/holding applications)

Mechanical & Environmental

• Housing Material: Aluminum (lightweight, corrosion-resistant, and thermally conductive)
• IP Class: IP54 (protected against dust ingress and water splashes; suitable for moderate environments)
• Explosion Safety (ATEX): No Protection (not designed for hazardous areas; ATEX-certified variants may be available)
• Standard: IEC (compliant with international norms for global market acceptance)

3. Key Advantages for Your Customers

• Compact & Lightweight Design: 11.6 kg weight makes installation and maintenance easier.
• High Torque Density: Helical-worm gearing ensures reliable torque transmission in a small footprint.
• Dual-Voltage Capability: Supports 220-230VΔ / 380-400VY, allowing flexibility in power supply configurations.
• SEW-EURODRIVE Quality: German-engineered for durability, precision, and long service life.
• IP54 Protection: Suitable for most industrial environments (dry to moderately dusty/wet conditions).

4. Recommended Applications

This geared motor is ideal for:

• Conveyor Systems (light-duty material handling, indexing)
• Mixers & Agitators (low-speed, high-torque mixing applications)
• Packaging Machinery (feeding, positioning, and rotating mechanisms)
• Pumps & Fans (where precise speed control and torque are required)
• General Automation (compact drive solutions for conveyors, feeders, and more)

Conclusion

The SEW SAF37 DRS71S4 is a high-quality, compact, and reliable geared motor suitable for a wide range of industrial applications. As a SEW-EURODRIVE supplier, your company can leverage this product’s strengths to meet customer demands for efficient, durable, and flexible

drive solutions.
