Ingersoll Rand 7545-B Reversible Air Power Motor provides pneumatic rotary output for machinery requiring gear-reduced speed with the flexibility to operate in either rotational direction. Rated at 0.25 HP and 2,700 RPM, this model uses a single gear reduction to deliver its specified output characteristics. Its reversible configuration supports equipment where forward and reverse rotation are required as part of the operating sequence.
The 7545-B develops 1.60 lb-ft stall torque, representing the torque produced when an applied load prevents the motor output from rotating. Together, the 2,700 RPM output, 0.25 HP rating, reversible operation, and single gear reduction provide important selection criteria for OEM designers, machine builders, and maintenance teams evaluating this air power motor for compatible machinery or a replacement pneumatic drive.
Type: Air Power Motor | Model: 7545-B | Rotation: Reversible | Power: 0.25 HP | Speed: 2,700 RPM | Stall Torque: 1.60 lb-ft | Gear Reduction: Single
Features:
- Pneumatic motor configuration provides rotary output from a compatible compressed-air supply.
- Reversible operation supports machinery requiring forward and reverse rotational motion.
- Single gear reduction provides the specified gear-reduced output configuration for compatible equipment.
- 0.25 HP rating provides a defined power reference for matching the motor to the driven mechanism.
- 2,700 RPM output supports applications requiring gear-reduced pneumatic rotary motion.
- 1.60 lb-ft stall torque provides a load reference when evaluating the motor against application requirements.
Made in USA: 
Applications:
- OEM machinery requiring reversible pneumatic rotary power.
- Automated mechanisms incorporating forward and reverse rotation into the machine cycle.
- Production equipment compatible with a 2,700 RPM gear-reduced motor output.
- Machine-building applications where single gear reduction and bidirectional operation match the required drive configuration.
- MRO replacement installations where the 7545-B performance ratings and mechanical interfaces match the existing motor.
FAQs:
- Q: Can the Ingersoll Rand 7545-B operate in both rotational directions?
A: Yes. The 7545-B is specified as a reversible air power motor for compatible machinery requiring bidirectional rotation. - Q: What is the output speed of the 7545-B?
A: The specified output speed is 2,700 RPM. - Q: What gear reduction configuration does the 7545-B use?
A: The 7545-B 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 the 7545-B?
A: The specified stall torque is 1.60 lb-ft. Stall torque represents torque developed when the applied load prevents the motor output from rotating. - Q: What should be verified before ordering the 7545-B as a replacement air motor?
A: Confirm that the application requires 0.25 HP, 2,700 RPM output, 1.60 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.
