Permanent Magnet Direct Drive (PMDD) Motor Used in Other Industry
Case Study
| PMDD Drum Motor in Laos Potash Mine Belt Conveyor |  |
Project Background
Deployed at Asia Potash International’s mining site in Laos, the PMDD drum motor replaced traditional "motor + gearbox + coupling" systems in the conveyor system. The harsh environment (C5-grade corrosion, acidic chloride ions, and high dust) demanded a robust solution.
Key Specifications
| Motor Type | Water-cooled PMDD drum motor |
| Power | 200 kW |
| Voltage | 660V |
| Belt Speed | 1.6 m/s |
| Transmission | Direct-drive (no gearbox) |
| Cooling | Integrated water-jacket cooling |
Advantages Demonstrated
• Energy Efficiency
15% lower energy consumption vs. induction motors, critical for 24/7 operations.
Eliminated gearbox losses (typical efficiency loss: 5–8%).
• Corrosion Resistance
Special coatings on motor housing and seals protected against acidic chloride ions.
Water-cooling maintained optimal temperature in high-ambient heat.
• Maintenance Reduction
Zero lubrication needs (vs. monthly gearbox maintenance).
Fewer moving parts cut downtime by 30%.
• Space Optimization
Compact design allowed installation in narrow mine shafts.
• Challenges & Solutions
Vibration Control: Added real-time monitoring to prevent resonance at low speeds.
Cooling Reliability: Redundant water cooling unit ensured uninterrupted cooling.
