Sumitomo PA136445 RNYMS02-1320YC-40 Gearmotor

The Sumitomo Drive PA136445 RNYMS02-1320YC-40 Gearmotor is an integrated drive unit for industrial applications. It combines an electric motor with a gear reducer to provide controlled speed and increased torque. The PA136445 and RNYMS02-1320YC-40 references identify the motor and gearbox configuration. The unit has a 40 ratio and is rated at 0.25 HP. It is used where compact size and reliable power transmission are important.

Motor and Gearbox Combination

The motor converts electrical energy into rotation. The gearbox reduces speed and multiplies torque. This allows the unit to drive loads that require lower output speed and higher force. The integrated design simplifies mounting and alignment. It also saves space compared with separate motor and reducer arrangements. The 40 ratio provides a strong reduction for applications that need slow, controlled output.

Performance and Control

The motor can be controlled by a suitable drive or starter. Speed may be fixed or adjustable depending on the system. The gearbox ratio determines the final output speed and torque. Users should compare the required torque, speed and duty cycle with the unit rating. Overloading can cause overheating, gear wear or premature failure. Proper ventilation and cooling help maintain performance.

Compatibility and Identification

The PA136445 and RNYMS02-1320YC-40 references are important for correct replacement. Mounting flange, shaft, key and electrical connections must match the machine. The gearbox output may be shaft mounted, flange mounted or foot mounted depending on configuration. Users should confirm these details before installation.

Applications

Typical applications include conveyors, mixers, feeders, packaging machinery, material handling, pumps and production lines. The unit is suitable for industrial environments where reliable speed reduction and torque are required. It can be used in new equipment or as a replacement in compatible systems.

Installation Notes

Installation should follow the equipment manual. The mounting base should be stable and aligned. Couplings, belts or chains must be aligned to avoid extra load. Electrical connections should match the motor voltage, frequency and phase. Grounding is required for safety. After installation, check rotation direction before connecting the load.

Lubrication and Cooling

The gearbox requires correct lubrication. Oil type and level depend on the design and mounting position. The motor should have sufficient airflow for cooling. Dust, heat and moisture can reduce service life. In harsh environments, guards or enclosures may be needed. Seals should be checked for leaks.

Maintenance

Regular maintenance includes checking oil level, leaks, noise, vibration and temperature. Worn seals should be replaced. Bearings and gears should be inspected during major service. Electrical terminals should be checked for tightness and signs of overheating. Following the service schedule helps maintain reliable operation.

Conclusion

The Sumitomo Drive PA136445 RNYMS02-1320YC-40 Gearmotor is a robust drive unit for industrial motion. It provides controlled speed, increased torque and dependable power transmission. Correct selection, installation and maintenance help ensure long service life.
