Permanent Magnet Direct Drive (PMDD) Motor Used in Pulp & Paper Industry

Project Overview

Customer	Hongta Renheng (Pulp & Paper Industry)
Location	Guangzhou City
Application	Refiner Pulper System
Retrofitted Solution	800kW, 6kV PMDD Motor

Challenge with Traditional Pulper Drives

The original system relied on gearboxes or belt-driven motors, which posed critical inefficiencies:

❌ High Maintenance – Frequent lubrication and belt/pulley replacements required.

❌ Oversized Motors – Conventional motors must be upscaled to handle high startup torque, resulting in low-load operation (<50% efficiency).

❌ Energy Waste – Underloaded motors operate at poor efficiency (≤80%), increasing electricity costs.

Our Solution

• Eliminated Gearbox/Belt – Maintenance-free design with zero mechanical transmission losses.
• Optimized for High Torque – Delivers 200% starting torque without motor oversizing.
• High Efficiency (≥96%) – Maintains peak performance even at variable loads.

Performance Results

Metric	Traditional Drive	PMDD Motor	Improvement
Energy Consumption	100% (Baseline)	75–80%	↓ 20–25%
Maintenance Cost	High (gearbox/belt)	Near-zero	↓ 90%
System Efficiency	≤80%	≥96%	↑ 16%+

Customer Benefits

• Proven Energy Savings – Reduced power costs by ¥[320,000]/year (calculated based on 24/7 operation/800kW).
• Reliability – No gearbox failures or belt slippage issues.
• Space Optimization – Compact design freed up floor space.
