Ingersoll Rand M004RHR000AR3 Multi-Vane Non-Reversible Air Motor provides high-speed pneumatic rotary power for machinery requiring continuous operation in a single rotational direction. Rated at 0.50 HP and 18,000 RPM, this model uses a multi-vane design to convert compressed-air energy into rotary motion for compatible OEM equipment, production machinery, and replacement installations. Its non-reversible configuration is intended for applications where bidirectional operation is not required.
The M004RHR000AR3 develops 0.40 lb-ft starting torque, which represents the torque available as the motor begins moving the connected load, and 0.53 lb-ft stall torque, which represents torque developed when the applied load prevents rotation. Together with the 18,000 RPM speed and 0.50 HP rating, these values give machine builders and maintenance professionals important performance references for matching the motor to the driven equipment.
Type: Multi-Vane Air Motor | Model: M004RHR000AR3 | Rotation: Non-Reversible | Power: 0.50 HP | Speed: 18,000 RPM | Starting Torque: 0.40 lb-ft | Stall Torque: 0.53 lb-ft
Features:
- Multi-vane pneumatic design converts compressed-air energy into continuous rotary output for compatible machinery.
- 0.50 HP power rating provides a defined specification for matching the motor to the requirements of the driven mechanism.
- 18,000 RPM output supports equipment requiring high-speed pneumatic rotation.
- 0.40 lb-ft starting torque provides a reference for evaluating the motor's ability to initiate movement of the connected load.
- 0.53 lb-ft stall torque helps equipment designers assess motor output when the applied load prevents rotation.
- Non-reversible configuration supports machinery designed for consistent single-direction operation.
Made in USA: 
Applications:
- OEM machinery requiring high-speed pneumatic rotary power.
- Automated equipment designed for continuous single-direction rotation.
- Production machinery compatible with the motor's specified horsepower, speed, and torque characteristics.
- Machine-building applications where compressed air is used as the rotary power source.
- MRO replacement installations where the M004RHR000AR3 performance ratings and mechanical interfaces match the existing equipment.
FAQs:
- Q: Is the Ingersoll Rand M004RHR000AR3 reversible?
A: No. The M004RHR000AR3 is specified as a non-reversible air motor for applications requiring rotation in one direction. - Q: What is the speed rating of this air motor?
A: The supplied product information specifies a speed of 18,000 RPM. - Q: How much starting torque does the M004RHR000AR3 provide?
A: This model is rated at 0.40 lb-ft starting torque, representing the torque available as the motor begins moving the connected load. - Q: What is the stall torque rating?
A: The specified stall torque is 0.53 lb-ft. Stall torque represents torque developed when the applied load prevents the motor output from rotating. - Q: What should be verified before installing this 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.
