Ingersoll Rand M002RHR004AR3 Multi-Vane Non-Reversible Air Motor provides pneumatic rotary power for equipment and machine designs requiring a compact, single-direction motor. This model is rated at 0.22 HP and 6,920 RPM, offering a lower-speed configuration than high-RPM air motors where the application places greater emphasis on available torque. Its multi-vane design converts compressed-air energy into rotary motion, while the non-reversible configuration is intended for installations that require rotation in one direction.
For OEM equipment, automation, and MRO applications, the M002RHR004AR3 provides 0.45 lb-ft starting torque and 0.61 lb-ft stall torque. Starting torque indicates the torque available as the motor begins rotating, while stall torque represents torque developed when the output is prevented from turning. These ratings give buyers useful reference points when matching the motor's output characteristics to the starting and load demands of the driven equipment.
Type: Multi-Vane Air Motor | Model: M002RHR004AR3 | Rotation: Non-Reversible | Power: 0.22 HP | Speed: 6,920 RPM | Starting Torque: 0.45 lb-ft | Stall Torque: 0.61 lb-ft
Features:
- Multi-vane pneumatic design converts compressed-air energy into continuous rotary output.
- 0.22 HP rating provides a defined power level for matching the motor to compatible machinery and driven equipment.
- 6,920 RPM speed supports applications requiring moderate-speed pneumatic rotary power.
- 0.45 lb-ft starting torque provides a useful reference when evaluating the load required to initiate rotation.
- 0.61 lb-ft stall torque helps equipment designers evaluate the motor against maximum load conditions where rotation may stop.
- Non-reversible configuration provides single-direction operation for machinery that does not require reversing capability.
Made in USA: 
Applications:
- OEM machinery requiring a pneumatic rotary power source.
- Automated equipment requiring continuous single-direction rotation.
- Machine-building applications compatible with the motor's horsepower, speed, and torque characteristics.
- Production equipment and mechanisms powered by compressed air.
- Replacement and MRO installations where the M002RHR004AR3 specifications and interfaces match the existing system requirements.
FAQs:
- Q: Is the Ingersoll Rand M002RHR004AR3 reversible?
A: No. This model is specified as non-reversible and is intended for applications requiring rotation in a single direction. - Q: How fast does the M002RHR004AR3 operate?
A: The supplied product information specifies a speed of 6,920 RPM. - Q: What are the starting and stall torque ratings?
A: The M002RHR004AR3 is rated at 0.45 lb-ft starting torque and 0.61 lb-ft stall torque. - Q: What does stall torque mean for an air motor?
A: Stall torque is the torque developed when the motor's output is prevented from rotating. It is an important value to consider when comparing the motor with the maximum load conditions of the application. - Q: What should be verified before installing this air motor?
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.
