Customized Z4 Series Motors Address Critical Production Challenges for An Indian Cable Manufacturer
An Indian high-voltage cable manufacturer faced three critical issues on its Continuous Casting and Rolling (CCR) line for copper rod production:
– Precision Speed Control : Required motors capable of maintaining ±0.1% speed stability to ensure 8mm rod diameter tolerance (IEC 60228 Class 1).
– Dust Infiltration : Original IP23-rated motors failed every 1,200 hours due to conductive copper dust penetrating internal components.
– High-Temperature Operation : Motors needed to operate at full capacity in 45°C ambient temperatures near induction heating furnaces without derating. Local suppliers lacked expertise in copper processing, while European solutions exceeded budget limits by 60%.
Tailored Solution
The upgraded Z4-400-32 motor (600 kW/440 V) was customized with 2 critical enhancements:
– Multi-stage dynamic sealing system : Combining air pressure isolation and specialized composite seals to block micron-level copper dust infiltration, extending service life to 8,000+ hours (IP54 protection).
– Adaptive cooling design : Dual air circulation channels and high-temperature-resistant insulation enabled stable operation at 55°C ambient temperatures with 15% lower temperature rise than industry standards.
