Frequency Conversion Impact on Metal Baler Efficiency
-
1. Low-Speed Efficiency OptimizationApplication: High-hardness metals (steel bars, thick plates)
• 15-20% peak force increase at reduced speeds
• Example: 1,000-ton baler at 50% speed achieves:
- Density increase: 2.0 → 2.4 t/m³ (car shells)
- Cycle time increase: 10-15% longer
• Benefits: Improved bale compactness enhances transport efficiency -
2. High-Speed Capacity BalanceApplication: Lightweight materials (cans, thin sheets)
• 20-30% faster cycles at 120% speed
• Case study: Aluminum processing capacity 8 → 10 tons/hour
Note: High-speed operation increases hydraulic temperature by 5-8°C - requires synchronized cooling activation -
3. Energy-Efficiency Dynamic Balance• 10-30% energy reduction via demand-based power adjustment
• Real-time torque matching for mixed materials (copper chips + steel shavings)
• 12-18% overall efficiency gain vs fixed-speed motors
Operational limit: Maintain frequency within 30-110% of rated value to prevent efficiency drop• Eliminates "big motor, small load" inefficiency
