Panpu Permanent Magnet Direct-Drive Motor Case: Kiri Chemical Rubber & Tire Plant – Whole-Line Drive System Energy Efficiency Retrofit
A tire manufacturer faced high overall energy consumption due to a diverse range of motor drive systems across its production line that operated independently without unified coordination. The project upgraded the drive systems for key processes—including mixing, calendering, and molding—by replacing legacy equipment with permanent magnet synchronous motors and variable frequency drives. An automated control system enabled synchronized multi-device operation. Post-retrofit results show significantly improved system efficiency, reduced overall energy consumption, and enhanced production stability and product consistency.

KEY METRICS
Integrated operation of the full-line drive system reduces overall energy consumption and enhances production line stability.
Data Scope and Validation Source: The above metrics are derived from on-site measurements under identical operating conditions before and after the retrofit (comparing energy meter readings with equipment operation logs). The statistical period covers 30 consecutive days of full operation post-retrofit. Motor energy efficiency ratings follow GB 18613-2020 and IEC 60034-30-1, while product efficiency values are cited from the manufacturer's factory test reports. Actual results may vary based on load rate, annual operating hours, and specific operating conditions.
