Radio Energy RE O444 R2B Tachogenerator with Sumitomo Gearbox
The Radio Energy RE O444 R2B 2X0.06 CA Tachogenerator with Sumitomo Gearbox is a speed feedback assembly for industrial drives. It combines a tachogenerator with a Sumitomo gearbox. The tachogenerator produces an AC voltage that is proportional to rotational speed. This signal is used by a drive or controller to regulate motor speed and monitor operation. The gearbox provides correct speed matching and mechanical coupling.
Tachogenerator Function
A tachogenerator is an electromechanical sensor. It converts rotational motion into an electrical signal. The output voltage amplitude and frequency change with speed. The control system reads this signal and compares it with a set point. The drive then adjusts motor power to maintain the required speed. This closed loop process improves accuracy and stability.
RE O444 R2B Configuration
The RE O444 R2B reference identifies the tachogenerator model and mounting configuration. The 2X0.06 CA marking indicates winding and output details. The unit may provide one or more output windings for speed feedback. Correct wiring and polarity are important for accurate control. The tachogenerator should be coupled to the gearbox without misalignment.
Sumitomo Gearbox Integration
The Sumitomo gearbox connects the tachogenerator to the driven machine. It provides the correct speed ratio and mechanical support. The gearbox must match the input and output shafts, flange and mounting pattern. Proper alignment helps reduce vibration and signal noise. The assembly is used where stable speed feedback is required.
Applications
Typical applications include industrial drives, machine tools, printing equipment, packaging machinery, material handling and process control. The tachogenerator is used in systems that require speed regulation, direction monitoring or feedback for tension control. It can be used in new designs or as a replacement in compatible systems.
Installation Notes
Installation should follow the equipment manual. The mounting surface should be clean and flat. Couplings should be aligned carefully. Bolts should be tightened to the correct torque. Electrical connections should match the controller input. Shielding may be needed to reduce electrical noise. After installation, check output voltage and signal stability across the speed range.
Maintenance
Regular maintenance includes checking for loose connections, worn couplings and abnormal noise. The tachogenerator should be kept clean and dry. Brushes or bearings may require service depending on design. The gearbox should be checked for leaks and lubrication. Signal quality should be verified during scheduled maintenance.
Conclusion
The Radio Energy RE O444 R2B Tachogenerator with Sumitomo Gearbox is a reliable speed feedback assembly for industrial control. It provides accurate speed signals and stable mechanical coupling. Correct installation and maintenance help ensure dependable performance.
