Applying the know-how gained from repairing railway vehicle motors to the repair of sewage pump motors!
Since our establishment, we have utilized the technical expertise gained from repairing railway vehicle motors to engage in the disassembly inspection and repair of sewage pumps. Both railway vehicle motors and sewage pump motors share the common requirement of stable operation over long periods in harsh environments. In particular, by applying the high-level taping processes and vacuum impregnation techniques required for railway vehicle motors in insulation treatment, we can expect improvements in insulation strength, enhanced moisture and corrosion resistance, and increased longevity. 【Main Achievements and Construction Scheme】 ■2024, City K: Output 1.5kW 4P / Diameter 65-80mm ■2025, City N: Output 22kW 4P / Diameter 150mm ■2025, City N: Output 3.7kW 2P / Diameter 65mm ■2025, City N: Output 5.5kW 4P / Diameter 100mm ■2026, JR West Japan (H Vehicle Depot): Output 3.7kW 4P / Diameter 100mm *For more details, please download the PDF or feel free to contact us.
