Ingersoll Rand 7534-B Non-Reversible Air Power Motor provides pneumatic rotary output for machinery requiring a lower-speed, single-direction drive. Rated at 0.25 HP and 900 RPM, this model uses double gear reduction to achieve its specified output characteristics. The non-reversible configuration is suited to equipment where the driven mechanism operates in one rotational direction without the need to reverse during the machine cycle.
The 7534-B develops 5.0 lb-ft stall torque, representing the torque produced when an applied load prevents the motor output from rotating. Its combination of 900 RPM output, 0.25 HP power rating, and double gear reduction provides important selection data for OEM designers, machine builders, and maintenance teams evaluating a pneumatic motor for compatible equipment or a replacement installation.
Type: Air Power Motor | Model: 7534-B | Rotation: Non-Reversible | Power: 0.25 HP | Speed: 900 RPM | Stall Torque: 5.0 lb-ft | Gear Reduction: Double
Features:
- Pneumatic motor configuration supplies rotary output from a compatible compressed-air source.
- Double gear reduction uses two stages of gearing to provide the specified reduced-speed output.
- 0.25 HP power rating provides a defined reference for matching the motor to compatible driven equipment.
- 900 RPM output supports machinery requiring gear-reduced pneumatic rotary motion.
- 5.0 lb-ft stall torque provides a load reference when evaluating the motor against application requirements.
- Non-reversible configuration supports mechanisms designed for consistent single-direction rotation.
Made in USA: 
Applications:
- OEM machinery requiring gear-reduced pneumatic rotary power in one direction.
- Production equipment compatible with a 900 RPM motor output.
- Machine-building applications designed around the specified horsepower and stall torque characteristics.
- Compressed-air-powered mechanisms where double gear reduction matches the required drive configuration.
- MRO replacement installations where the 7534-B performance ratings and mechanical interfaces match the existing motor.
FAQs:
- Q: Is the Ingersoll Rand 7534-B reversible?
A: No. The 7534-B is specified as a non-reversible air power motor for compatible equipment requiring rotation in one direction. - Q: What is the output speed of the 7534-B?
A: The specified output speed is 900 RPM. - Q: Does the 7534-B use single or double gear reduction?
A: The 7534-B is specified with double gear reduction, meaning two stages of gearing are used to reduce rotational speed to the specified output. - Q: What is the stall torque of this air power motor?
A: The 7534-B is rated at 5.0 lb-ft stall torque. Stall torque represents torque developed when the applied load prevents the motor output from rotating. - Q: What should be checked before using the 7534-B as a replacement motor?
A: Verify that the application requires 0.25 HP, 900 RPM output, 5.0 lb-ft stall torque, non-reversible operation, and double gear reduction. Shaft, mounting, dimensional, and compressed-air requirements should also be confirmed against the manufacturer catalog before installation.
