Industrial Motor Production — High-Voltage Winding Lines for Heavy-Duty Applications
Project Overview
Designed and implemented a complete high-voltage motor coil winding and VPI (Vacuum Pressure Impregnation) line for an industrial motor manufacturer serving the mining and heavy machinery sectors.
Challenge
The client's existing manual winding process faced multiple operational challenges:
· Inconsistent coil winding quality leading to premature motor failures
· Long lead times for custom high-voltage motor configurations
· Safety risks for operators handling heavy coils and VPI chemicals
· Limited capacity to meet surging demand for energy-efficient industrial motors
Our Solution
Engineered a comprehensive automated production system:
· High-Precision Coil Winders: CNC-controlled winding machines with automatic wire tensioning and layer counting
· Automated Coil Handling: Robotic systems for coil transfer between winding, insertion, and VPI stations
· VPI System Integration: Automated vacuum pressure impregnation line with precise resin control and curing ovens
· Quality Control: In-line insulation testing and high-voltage withstand testing
· Material Support: Consistent supply of copper fin tubes, thermal conductive materials, and specialty resins
Results
· Quality excellence: Zero coil-related failures reported in the first 12 months of operation
· Lead time reduction: Custom motor delivery time reduced from 8 weeks to 3 weeks
· Capacity increase: Production capacity expanded by 60% without additional floor space
· Safety enhancement: Eliminated 100% of manual handling risks in the VPI process
