Nidec DJ30P1DM - The special application close-coupled pump three-phase motors are designed for direct integration with centrifugal pumps, where the pump impeller is mounted directly on the motor shaft. These motors are specifically engineered to meet the demanding requirements of pump applications in damp, dusty, or dirty environments. With features such as class F insulation, rolled steel frame construction, regreasable bearings, and double shielded bearings, these motors offer reliable and efficient operation. They are designed for 40°C ambient temperature and NEMA Design B performance on 60 Hz power supply. The motors come in various frame sizes, with "JM" shafts for mechanical seal compatibility, ensuring easy integration and reliable performance in close-coupled pump systems.
