Ingersoll Rand 1801Q Non-Reversible Multi-Vane Air Motor is designed to provide dependable pneumatic rotary power for industrial applications requiring high output torque at reduced operating speeds. Delivering 1.35 HP with a free speed of 650 RPM, this 1801 Series air motor utilizes a durable multi-vane design to produce smooth, continuous power for demanding industrial environments. Its non-reversible configuration ensures reliable single-direction rotation, making it well suited for OEM machinery, conveyors, mixers, material handling equipment, packaging systems, and other compressed-air powered industrial applications.
The 1801Q develops a 30.0 lb-ft starting torque, providing substantial breakaway force to initiate rotation under heavier loads, and a 40 lb-ft stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. This combination of moderate speed and increased torque makes the motor ideal for equipment requiring controlled rotary motion and dependable pneumatic performance.

FAQs:
- Q: Is the Ingersoll Rand 1801Q reversible?
A: No. This model is a non-reversible air motor designed for continuous operation in one direction. - 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 torque delivery. - Q: What is the rated free speed?
A: The manufacturer specifies a free speed of 650 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.
