Ingersoll Rand M002RHR101AR3 Multi-Vane Non-Reversible Air Motor provides low-speed pneumatic rotary output for machinery where higher starting and stall torque are important selection factors. Rated at 0.16 HP and 228 RPM, this model uses a multi-vane design to convert compressed-air energy into continuous rotary motion. Its non-reversible configuration is intended for equipment that requires rotation in a single direction rather than bidirectional operation.
The M002RHR101AR3 develops 8.32 lb-ft starting torque, which indicates the torque available as the motor begins moving a connected load, and 11.1 lb-ft stall torque, the torque developed when the applied load prevents rotation. Combined with its 228 RPM output, these ratings make the model relevant for OEM machinery, automated mechanisms, and replacement installations where lower rotational speed and the specified torque characteristics match the driven equipment.
Type: Multi-Vane Air Motor | Model: M002RHR101AR3 | Rotation: Non-Reversible | Power: 0.16 HP | Speed: 228 RPM | Starting Torque: 8.32 lb-ft | Stall Torque: 11.1 lb-ft
Features:
- Multi-vane pneumatic motor design provides continuous rotary output from a compatible compressed-air supply.
- 0.16 HP rating gives equipment designers a defined power specification for matching the motor to the driven mechanism.
- 228 RPM output is suited to applications requiring comparatively low-speed pneumatic rotation.
- 8.32 lb-ft starting torque provides an important reference when determining whether the motor can initiate movement of the connected load.
- 11.1 lb-ft stall torque helps designers evaluate motor output under a condition where the applied load prevents rotation.
- Non-reversible design supports machinery requiring consistent single-direction rotary operation.
Made in USA: 
Applications:
- OEM machinery requiring low-speed pneumatic rotary power.
- Automated mechanisms designed for continuous single-direction rotation.
- Production equipment compatible with the motor's 228 RPM speed and specified torque characteristics.
- Machine-building applications where compressed air is used to power a rotary mechanism.
- MRO replacement installations where the M002RHR101AR3 performance ratings and mechanical interfaces match the existing equipment.
FAQs:
- Q: Is the Ingersoll Rand M002RHR101AR3 reversible?
A: No. The M002RHR101AR3 is specified as a non-reversible air motor and is intended for equipment requiring rotation in one direction. - Q: What is the speed of the M002RHR101AR3?
A: The supplied product information specifies a speed of 228 RPM. - Q: What is the starting torque of this air motor?
A: The M002RHR101AR3 is rated at 8.32 lb-ft starting torque, representing the torque available as the motor begins moving the connected load. - Q: How much stall torque does the M002RHR101AR3 provide?
A: The specified stall torque is 11.1 lb-ft. Stall torque represents torque developed when the load prevents the motor output from rotating. - Q: What should be verified before ordering this air motor?
A: Confirm 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 verified against the manufacturer catalog before installation.
