Ingersoll Rand 1841N Reversible Multi-Vane Air Motor is designed to provide dependable pneumatic rotary power for industrial equipment requiring bidirectional operation, moderate operating speeds, and reliable torque output. Delivering 1.20 HP with a free speed of 1,700 RPM, this 1841 Series air motor features a durable multi-vane design that provides smooth, continuous power delivery for demanding industrial applications. Its reversible configuration allows clockwise and counterclockwise rotation, making it well suited for OEM machinery, indexing equipment, conveyors, industrial processing systems, packaging machinery, and other compressed-air powered applications requiring flexible directional control.
The 1841N develops a 9.3 lb-ft starting torque, helping initiate rotation under load, and a 12.5 lb-ft stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. This combination of controlled speed, dependable horsepower, and reversing capability makes the motor an excellent solution for industrial equipment requiring smooth pneumatic rotary performance.

FAQs:
- Q: Is the Ingersoll Rand 1841N reversible?
A: Yes. This model is designed to operate in both clockwise and counterclockwise directions for applications requiring bidirectional shaft rotation. - Q: What is a multi-vane air motor?
A: A multi-vane air motor uses sliding vanes inside a rotor to convert compressed air into smooth, continuous rotary motion with consistent power delivery. - Q: What is the rated free speed?
A: The manufacturer specifies a free speed of 1,700 RPM. - Q: What is the difference between starting torque and stall torque?
A: Starting torque is the torque available to begin rotating a load from rest, while stall torque is the maximum torque the motor develops when the output shaft is prevented from rotating. - Q: What should be verified before installation?
A: Confirm horsepower, free speed, rotation direction, shaft dimensions, mounting arrangement, and compressed-air requirements using the Ingersoll Rand Air Motor Catalog before installation.
