Ingersoll Rand 3840Q Multi-Vane Reversible Air Motor | Series 3840 | 1.35 HP | 280 RPM | 60 (ft-lbs) Starting Torque | 80 (ft-lbs) Stall Torque

Ingersoll Rand 3840Q Multi-Vane Reversible Air Motor is designed to provide dependable pneumatic rotary power for industrial applications requiring substantial torque, controlled operating speeds, and bidirectional operation. Part of the 3840 Series, this air motor delivers 1.35 HP with a free speed of 280 RPM. Its durable multi-vane design converts compressed air into smooth, continuous rotary motion, while the reversible configuration enables both clockwise and counterclockwise rotation for equipment that requires flexible directional control.

The 3840Q develops 60 ft-lbs starting torque, providing strong breakaway force to initiate rotation under heavier loads, and 80 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. This combination of lower operating speed, dependable horsepower, and reversible capability makes the motor well suited for OEM machinery, indexing systems, conveyors, material handling equipment, industrial processing machinery, and other compressed-air powered applications.

FAQs:

• Q: Is the Ingersoll Rand 3840Q 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 280 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 developed 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.
