Ingersoll Rand 3840M Multi-Vane Reversible Air Motor | Series 3840 | 1.4 HP | 825 RPM | 23 (ft-lbs) Starting Torque | 31.5 (ft-lbs) Stall Torque

Ingersoll Rand 3840M Multi-Vane Reversible Air Motor is designed to deliver dependable pneumatic rotary power for industrial equipment requiring bidirectional operation, moderate operating speeds, and reliable torque output. Part of the 3840 Series, this air motor produces 1.4 HP with a free speed of 825 RPM. Its durable multi-vane design converts compressed air into smooth, continuous rotary motion, while the reversible configuration allows both clockwise and counterclockwise operation for applications requiring flexible directional control.

The 3840M develops 23 ft-lbs starting torque, providing dependable breakaway force to initiate rotation under load, and 31.5 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. This balance of horsepower, operating speed, torque, and reversible operation makes the motor well suited for OEM machinery, indexing systems, conveyors, processing equipment, and other compressed-air powered industrial applications.

FAQs:

• Q: Is the Ingersoll Rand 3840M 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 825 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.
