Ingersoll Rand M002RHR028AR3 Multi-Vane Non-Reversible Air Motor provides lower-speed pneumatic rotary output for machinery and equipment requiring increased starting and stall torque. Rated at 0.19 HP and 860 RPM, this model uses a multi-vane design to convert compressed-air energy into continuous rotary motion. Its non-reversible configuration is intended for installations where the driven equipment requires rotation in a single direction.
With 2.92 lb-ft starting torque and 3.90 lb-ft stall torque, the M002RHR028AR3 gives machine builders and maintenance professionals defined load characteristics for motor selection. Starting torque indicates the torque available as the motor begins moving the connected load, while stall torque represents torque developed when the load prevents rotation. Together with its 860 RPM speed rating, these values help determine whether this motor matches the operating requirements of an OEM machine, automated mechanism, or replacement installation.
Type: Multi-Vane Air Motor | Model: M002RHR028AR3 | Rotation: Non-Reversible | Power: 0.19 HP | Speed: 860 RPM | Starting Torque: 2.92 lb-ft | Stall Torque: 3.90 lb-ft
Features:
- Multi-vane pneumatic motor design converts compressed-air energy into continuous rotary output.
- 0.19 HP rating provides a defined power specification for matching the motor to compatible machinery and driven equipment.
- 860 RPM speed supports applications that require lower-speed pneumatic rotary motion.
- 2.92 lb-ft starting torque provides a reference for evaluating the motor's ability to initiate movement of the connected load.
- 3.90 lb-ft stall torque helps equipment designers evaluate motor output when the applied load prevents rotation.
- Non-reversible configuration supports equipment designed for continuous rotation in a single direction.
Made in USA: 
Applications:
- OEM machinery requiring lower-speed pneumatic rotary power.
- Automated mechanisms designed for continuous single-direction operation.
- Production equipment compatible with the motor's specified horsepower, speed, and torque characteristics.
- Machine-building projects where compressed air is used as the rotary power source.
- MRO replacement applications where the M002RHR028AR3 performance ratings and mechanical interfaces match the existing equipment.
FAQs:
- Q: Is the Ingersoll Rand M002RHR028AR3 reversible?
A: No. The M002RHR028AR3 is specified as a non-reversible air motor for equipment requiring rotation in one direction. - Q: What is the operating speed of this air motor?
A: The supplied product information specifies a speed of 860 RPM. - Q: How much starting torque does the M002RHR028AR3 provide?
A: This model is rated at 2.92 lb-ft starting torque, which indicates the torque available as the motor begins rotating the connected load. - Q: What is the stall torque rating?
A: The M002RHR028AR3 has a specified stall torque of 3.90 lb-ft. Stall torque refers to torque developed when the load prevents the motor output from rotating. - Q: What should be checked before selecting this motor for an existing machine?
A: Verify that the required horsepower, speed, starting torque, stall torque, and non-reversible operation match the application. Shaft, mounting, dimensional, and compressed-air requirements should also be checked against the manufacturer catalog before installation.
