Pair our high-performance helical speed reduction gearboxes with our globally certified AC motor portfolio, designed to meet every efficiency requirement across your operation.
Our 4-pole DRS AC motors (sizes 80M to 225MC) meet EFF2 requirements as standard-efficiency workhorses, while the same size range also covers EFF1-class energy-efficient models for facilities prioritizing lower energy consumption. For operations targeting maximum energy savings, our premium-efficiency DRS variants (sizes 90M to 225MC) significantly exceed EFF1 standards, cutting long-term operating costs while maintaining the same compact footprint.
All our 4-pole AC motors – including DRS (sizes 71S to 80M), DRE (sizes 80M to 225MC), and DRP (sizes 90M to 225MC) models – comply with Australia and New Zealand’s MEPS 2006 energy efficiency regulations. Approvals for North American (USA, Canada) and Brazilian markets are currently in progress, ensuring seamless integration into your global supply chain.
Built with robust corrosion-resistant surface protection, our gearmotors are engineered to withstand harsh industrial environments, delivering reliable performance across manufacturing, material handling, and processing applications.
