Ingersoll Rand M002RHR008AR3 Multi-Vane Non-Reversible Air Motor is designed for pneumatic rotary applications that require lower operating speed with increased torque compared with higher-speed motor configurations. Rated at 0.22 HP and 3,240 RPM, this model uses a multi-vane air motor design to convert compressed-air energy into continuous rotary output. Its non-reversible configuration is intended for equipment that requires rotation in a single direction.
For OEM machinery, automated systems, and MRO replacement applications, the M002RHR008AR3 provides 0.98 lb-ft starting torque and 1.31 lb-ft stall torque. Starting torque represents the torque available as the motor begins to rotate, while stall torque represents the torque developed when the output is prevented from turning. These ratings help machine builders and maintenance professionals compare the motor's available output with the starting and load requirements of the driven equipment.
Type: Multi-Vane Air Motor | Model: M002RHR008AR3 | Rotation: Non-Reversible | Power: 0.22 HP | Speed: 3,240 RPM | Starting Torque: 0.98 lb-ft | Stall Torque: 1.31 lb-ft
Features:
- Multi-vane pneumatic motor design provides continuous rotary output from a compatible compressed-air supply.
- 0.22 HP power rating provides a defined reference for matching the motor to compatible machinery and equipment.
- 3,240 RPM operating speed supports applications where lower-speed rotary output is preferred.
- 0.98 lb-ft starting torque provides a useful reference when evaluating the load required to initiate rotation.
- 1.31 lb-ft stall torque helps equipment designers compare motor capability with maximum load conditions.
- Non-reversible configuration supports installations that require rotation in one direction only.
Made in USA: 
Applications:
- OEM machinery requiring a pneumatic rotary power source.
- Automated equipment requiring continuous single-direction operation.
- Machine-building applications compatible with the motor's speed, horsepower, and torque characteristics.
- Production equipment and mechanisms powered by compressed air.
- MRO and replacement installations where the M002RHR008AR3 specifications and interfaces match the existing equipment requirements.
FAQs:
- Q: Is the Ingersoll Rand M002RHR008AR3 reversible?
A: No. The M002RHR008AR3 is specified as a non-reversible air motor and is intended for applications requiring rotation in a single direction. - Q: What is the operating speed of this air motor?
A: The supplied product information specifies a speed of 3,240 RPM. - Q: What are the starting and stall torque ratings?
A: The M002RHR008AR3 is rated at 0.98 lb-ft starting torque and 1.31 lb-ft stall torque. - Q: Why are starting torque and stall torque important when selecting an air motor?
A: Starting torque helps indicate whether the motor can begin rotating the connected load, while stall torque provides a reference for the torque developed when rotation stops under load. - Q: What should be verified before integrating this motor into equipment?
A: Confirm that the required horsepower, operating 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.
