Permanent Magnet Direct Drive Solution Paves the Way for Major Hydropower Projects
On July 19th, the downstream hydropower project of the Yarlung Zangbo River officially commenced in Tibet, marking the full launch of this national "14th Five-Year Plan" key clean energy initiative. Located in a high-altitude canyon region, the project features massive scale, long construction cycles, complex systems, and harsh environmental conditions, making it another strategically significant hydropower endeavor following the Three Gorges and Baihetan projects. For equipment manufacturers involved, not only must their products demonstrate high reliability and efficiency, but they must also possess a deep understanding of system integration and adaptability to diverse operational scenarios.
Jiangsu Jasung, a specialized manufacturer focused on industrial permanent magnet motor technology, has long dedicated itself to the advancement and system integration of permanent magnet direct drive (PMDD) solutions. By refining motor performance and engineering adaptability for heavy-duty, continuous, and high-frequency control scenarios, the company has established a strong foundation for serving major national projects.
In the aggregates industry, Jasung has developed comprehensive solutions covering "main equipment drives + aggregate systems + auxiliary processes." Its products have demonstrated exceptional performance in large-scale hydropower, water conservancy, mining, and port infrastructure projects, proving their readiness for critical national initiatives.
01 Superior Adaptability: The Advantages of PMDD
Compared to traditional drive solutions, Jasung’s PMDD motor systems offer the following key benefits:
• Compact Structure: Eliminates gear reducers, ensuring higher efficiency, lower noise, and reduced vibration, ideal for space-constrained or noise-sensitive environments.
• Low-Speed, High-Torque Output: Optimized for heavy-duty starts/stops and continuous speed regulation, delivering rapid response and precise control.
• Robust Protection: Designed for dustproof, moisture-resistant, and corrosion-resistant operation, capable of long-term performance in high-altitude, humid, and high-dust conditions.
• Smart Control & Remote Diagnostics: Integrated communication protocols enable real-time monitoring and predictive maintenance, simplifying long-term operations.
02 Key Applications: Tailored Solutions for Hydropower Systems
Based on proven field experience, Jiasuan has developed standardized or customized PMDD solutions for critical hydropower systems:
Gate Hoist Drive Systems
Used in dam gates, spillways, and flow control structures, PMDD motors replace traditional gear-driven mechanisms, offering:
✔ Direct high-torque output for faster response and precise positioning.
✔ 50% lower noise and minimal maintenance, ideal for high-frequency cycling and long service life.
Ship Lift Drive Systems
For heavy-load, high-safety lifting applications, Jiasuan’s low-speed, high-torque PMDD motors eliminate bulky gearboxes, ensuring:
✔ Smoother operation and higher reliability in vertical ship transportation.
03 Complete Aggregate Processing Drive Solutions
From crushing and screening to conveying and stacking, Jasung’s PMDD systems excel across the entire aggregates workflow:
Belt Conveyor Drives
• Ultra-low-speed outer-rotor PMDD drums replace gearboxes, couplings, and induction motors, offering:
✔ 80% space savings, 75% fewer maintenance parts, and 20%+ energy savings.
✔ Ideal for confined-space material handling in hydropower construction.
Vibrating Screen Drives
• PMDD solutions for coarse, medium, and fine screening, eliminating resonance issues and improving screening efficiency by 15%.
Crusher Drives
• High-impact-resistant PMDD motors for secondary/tertiary crushing (hammer, impact, jaw crushers), handling intermittent loads and high-inertia starts.
Pump & Fan Drives
• PMDD motors halve the size of traditional induction motors while reducing temperature rise and improving stability, cutting energy use by 20-30%.
Driving Innovation, Securing Competitive Edge
The evolving demands of clean energy infrastructure require drive systems that go beyond basic functionality—they must deliver peak efficiency, precision, controllability, and longevity. These are the critical differentiators shaping the future of domestic industrial technology.
