SEW-EURODRIVE WA20 DRS71S4 Helical-Worm Geared Motor Combining Helical and Worm

SEW-EURODRIVE WA20 DRS71S4 Helical-Worm Geared Motor Overview

As a reliable supplier of SEW-EURODRIVE products, your company can offer the WA20/DRS71S4 geared motor, a compact, efficient, and cost-effective solution for light-duty industrial applications. Below is a detailed breakdown of its specifications and features to support your sales and technical discussions with customers.

1. Key Specifications

2. Technical & Performance Features

Power & Speed

• Rated Power: 0.37 kW (ideal for low-power, continuous-duty applications)
• Motor Speed (50Hz, 4-Pole): 1500 rpm (standard synchronous speed)
• Output Speed:
  $\text{Output Speed}=\genfrac{}{}{0ex}{}{1500}{14}\approx 107\text{rpm}$ (due to gear ratio)
• Frequency: 50 Hz (optimized for European and other 50Hz markets)

Gearbox

• Gear Ratio (i = n₁/n₂): 14:1 (provides a moderate speed reduction with good torque multiplication)
• Type: Helical-Worm (combines helical gears for smooth operation 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: IE1 (EFF2) (compliant with older efficiency 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: IP55 (higher dust and water protection than IP54; suitable for more demanding 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

• Ultra-Lightweight Design: 8.68 kg weight reduces installation complexity and costs.
• High Torque Density: Helical-worm gearing ensures reliable torque transmission in a compact package.
• 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.
• IP55 Protection: Suitable for moderately dusty or wet environments (e.g., outdoor installations, food processing).
• Competitive Pricing: As a supplier, you can offer this model at an attractive price point.

4. Recommended Applications

This geared motor is ideal for:

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

5. Potential Limitations & Solutions
