Ingersoll Rand 7540-B Non-Reversible Air Power Motor provides pneumatic rotary output for machinery requiring a single-direction, gear-reduced drive. Rated at 0.25 HP and 2,700 RPM, this model uses a single gear reduction to deliver its specified output characteristics. The non-reversible configuration is suited to equipment where the driven mechanism operates in one rotational direction and does not require forward-and-reverse functionality.
The 7540-B develops 1.75 lb-ft stall torque, which is the torque produced when the applied load prevents the motor output from rotating. This rating provides an important reference when evaluating load requirements, while the 2,700 RPM output and 0.25 HP power rating help buyers match the motor to compatible machinery. Its single gear reduction configuration is also an important consideration when specifying the 7540-B for OEM equipment or an existing pneumatic motor installation.
Type: Air Power Motor | Model: 7540-B | Rotation: Non-Reversible | Power: 0.25 HP | Speed: 2,700 RPM | Stall Torque: 1.75 lb-ft | Gear Reduction: Single
Features:
- Pneumatic motor configuration provides rotary output from a compatible compressed-air supply.
- Single gear reduction provides a gear-reduced output configuration with a specified speed of 2,700 RPM.
- 0.25 HP rating provides a defined power specification for matching the motor to compatible driven equipment.
- 2,700 RPM output provides an important speed reference when integrating the motor into machinery.
- 1.75 lb-ft stall torque provides a load reference for evaluating the motor against application requirements.
- Non-reversible configuration supports machinery designed for consistent single-direction rotation.
Made in USA: 
Applications:
- OEM machinery requiring single-direction pneumatic rotary power.
- Production equipment compatible with a 2,700 RPM gear-reduced motor output.
- Machine-building applications designed around the motor's 0.25 HP power rating and specified stall torque.
- Compressed-air-powered mechanisms where a single gear reduction configuration matches the equipment requirements.
- MRO replacement installations where the 7540-B performance ratings and mechanical interfaces match the existing motor.
FAQs:
- Q: Is the Ingersoll Rand 7540-B reversible?
A: No. The 7540-B is specified as a non-reversible air power motor and is intended for equipment requiring rotation in one direction. - Q: What is the output speed of the Ingersoll Rand 7540-B?
A: The 7540-B is specified at 2,700 RPM. - Q: Does the 7540-B use single or double gear reduction?
A: This model is specified with single gear reduction. This distinguishes it from air motor configurations that use two stages of gear reduction. - Q: What is the stall torque rating of the 7540-B?
A: The specified stall torque is 1.75 lb-ft. Stall torque represents the torque developed when the applied load prevents the motor output from rotating. - Q: What specifications should be matched when replacing an existing motor with the 7540-B?
A: Verify the 0.25 HP rating, 2,700 RPM output, 1.75 lb-ft stall torque, non-reversible operation, and single gear reduction configuration against the application. Mechanical interfaces and compressed-air requirements should also be confirmed before installation.
