Ingersoll Rand 7547-C Reversible Air Power Motor provides high-speed pneumatic rotary output for machinery that requires the ability to operate in either rotational direction. Rated at 0.25 HP and 20,000 RPM, this model uses a single gear reduction to deliver its specified output characteristics. Its reversible configuration makes it suitable for compatible equipment where forward and reverse rotation are required as part of the machine or process cycle.
The 7547-C develops 0.22 lb-ft stall torque, representing the torque produced when the applied load prevents the motor output from rotating. The combination of 20,000 RPM output, 0.25 HP power, reversible operation, and single gear reduction gives OEM designers, machine builders, and maintenance professionals important selection criteria when matching the motor to compatible equipment or an existing pneumatic drive.

Made in USA: 
Applications:
- OEM machinery requiring high-speed reversible pneumatic rotary power.
- Automated mechanisms where forward and reverse rotation are incorporated into the operating cycle.
- Production equipment compatible with a 20,000 RPM motor output.
- Machine-building applications where single gear reduction and bidirectional operation match the required drive configuration.
- MRO replacement installations where the 7547-C performance ratings and mechanical interfaces match the existing motor.
FAQs:
- Q: Is the Ingersoll Rand 7547-C reversible?
A: Yes. The 7547-C is specified as a reversible air power motor for compatible machinery requiring rotation in either direction. - Q: What is the output speed of the 7547-C?
A: The specified output speed is 20,000 RPM. - Q: What gear reduction configuration does the 7547-C use?
A: The 7547-C is specified with single gear reduction. This configuration should be matched to the requirements of the driven equipment when selecting or replacing an air motor. - Q: What is the stall torque rating of this air power motor?
A: The 7547-C is rated at 0.22 lb-ft stall torque. Stall torque represents torque developed when the applied load prevents the motor output from rotating. - Q: What should be verified before installing the 7547-C?
A: Confirm that the application requires 0.25 HP, 20,000 RPM output, 0.22 lb-ft stall torque, reversible operation, and single gear reduction. Shaft, mounting, dimensional, and compressed-air requirements should also be verified against the manufacturer catalog before installation.
