Ingersoll Rand 1841P Reversible Multi-Vane Air Motor is designed to provide dependable pneumatic rotary power for industrial applications requiring increased torque, controlled operating speeds, and bidirectional operation. Delivering 1.10 HP with a free speed of 900 RPM, this 1841 Series air motor utilizes a durable multi-vane design that provides smooth, continuous power delivery for demanding industrial environments. Its reversible configuration enables both clockwise and counterclockwise rotation, making it well suited for OEM machinery, indexing equipment, conveyors, processing systems, packaging equipment, and other compressed-air powered applications requiring flexible directional control.
The 1841P develops a 15.0 lb-ft starting torque, helping overcome startup loads, and a 20.0 lb-ft stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. The combination of controlled speed, dependable horsepower, and reversing capability makes this motor an excellent solution for industrial equipment requiring reliable pneumatic rotary performance.

FAQs:
- Q: Is the Ingersoll Rand 1841P 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 900 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.
