In early 2025, a well-known building materials manufacturer in Eastern Europe announced the completion of a major production-line upgrade, and at the core of the transformation was a full replacement of its drive system with induction motor three phase units supplied by Wolong Nanyang Motor. The factory, built more than 25 years ago, had been struggling with frequent equipment failures, rising energy costs, and increasingly unstable output quality. Management had been searching for a reliable modernization solution for years—one that could scale, withstand heavy loads, and reduce downtime.
The breakthrough came when Wolong Nanyang Motor engineering team conducted a comprehensive on-site assessment. They identified that the plant’s outdated motors were operating far below modern efficiency standards and suffered from poor torque response during peak operations.
Installation began with the plant’s most problematic section—the high-load compression and mixing zone. This area demanded motors that could endure long operating hours and maintain consistent torque under shock loads. The induction motor three phase solution from Wolong Nanyang Motor introduced an upgraded rotor structure, optimized copper windings, and enhanced heat dissipation systems. After commissioning, the production manager immediately noticed that startup currents were lower and torque fluctuations had nearly disappeared. With fewer vibrations, mechanical maintenance intervals extended significantly.
The second phase of the upgrade focused on conveyor and drying systems, which required precise speed stability to maintain product uniformity. Wolong Nanyang Motor integrated its induction motor three phase units with the factory’s existing VFD platform, allowing for seamless speed control and quick calibration. Operators reported that product consistency improved by more than 15%, and the plant experienced almost zero unplanned shutdowns during the first months of operation—something unheard of in prior years.
Energy savings were another major surprise. Initial data collected over a six-month period showed that the new system reduced total electricity consumption by approximately 18%. This drop was largely attributed to the motors’ improved efficiency and reduced heat losses. According to the factory’s energy-management team, this alone offset nearly a third of the project’s investment cost.
