Ingersoll Rand 4840M Reversible Multi-Vane Air Motor | 3.2 HP | 975 RPM | 47.3 (ft-lbs) Starting Torque | 63.0 (ft-lbs) Stall Torque

Description

Ingersoll Rand 4840M Reversible Multi-Vane Air Motor is designed to provide dependable pneumatic rotary power for industrial applications requiring increased torque output, controlled operating speed, and bidirectional operation. Part of the 4800 Series, this air motor delivers 3.2 HP with a free speed of 975 RPM. Its multi-vane design converts compressed air into smooth, continuous rotary motion, while the reversible configuration allows clockwise and counterclockwise operation for equipment requiring flexible directional control.The 4840M provides 47.3 ft-lbs starting torque, offering a reference for the torque available to initiate rotation from rest, and 63.0 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. With its combination of horsepower, moderate operating speed, and reversible functionality, this air motor is suited for OEM machinery, production equipment, rotary drive systems, and other applications requiring reliable compressed-air power with directional flexibility.Type: Multi-Vane Air Motor | Series: 4800 Series | Model: 4840M | Rotation: Reversible | Power: 3.2 HP | Free Speed: 975 RPM | Starting Torque: 47.3 ft-lbs | Stall Torque: 63.0 ft-lbsFeatures:Multi-vane air motor design provides smooth and consistent pneumatic rotary power.Reversible configuration allows clockwise and counterclockwise operation for flexible equipment integration.3.2 HP output provides dependable pneumatic power for compatible industrial machinery.975 RPM free speed offers a balance of operating speed and torque capability.47.3 ft-lbs starting torque provides a manufacturer-published reference for startup torque capability.63.0 ft-lbs stall torque provides a manufacturer-published reference for maximum torque output under stalled conditions.4800 Series motor design supports OEM integration and replacement applications where specifications match.Compressed-air operation provides a practical alternative to electrically powered rotary drives in suitable environments.Tech Tip:To increase tool performance, extend tool life and lessen repair costs useit with aFilter-Regulator-Lubricator(FRLs)Made in USA: Applications:OEM machinery requiring reversible pneumatic rotary power.Industrial production and processing equipment.Rotary drive systems requiring bidirectional operation.Material handling and automated equipment applications.Replacement installations where motor specifications match the existing equipment requirements.FAQs:Q: Is the Ingersoll Rand 4840M reversible?A: Yes. This model is specified as a reversible air motor and can operate in both clockwise and counterclockwise directions.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 rotary motion.Q: What is the rated free speed of the 4840M?A: The manufacturer specifies a free speed of 975 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 produced when the output shaft is prevented from rotating.Q: What should be verified before installation?A: Confirm horsepower, speed requirements, rotation direction, shaft dimensions, mounting configuration, and compressed-air requirements using the Ingersoll Rand Air Motor Catalog before installation. .spec-accordion{width:100%;max-width:1200px;margin:1em auto;font-family:”Montserrat”,Arial,sans-serif;box-sizing:border-box} .spec-accordion *{box-sizing:border-box} .spec-accordion-toggle{width:100%;background:#444;color:#fff;text-transform:uppercase;border:none;padding:12px;font-size:16px;font-weight:700;text-align:center;cursor:pointer;position:relative} .spec-accordion-toggle .icon{position:absolute;right:15px;font-size:20px} .spec-accordion-panel{padding-top:10px} .spec-table-wrapper{width:100%;max-width:1200px;margin:auto;overflow-x:auto} .spec-table{width:100%!important;min-width:100%;border-collapse:collapse;font-family:”Montserrat”,Arial,sans-serif;font-size:12px} .spec-table th{background:#444;color:#fff;text-transform:uppercase;padding:8px 6px;border:1px solid #ddd} .spec-table td{padding:6px;border:1px solid #eee;text-align:center} .spec-table tbody tr:nth-child(even){background:#f7f7f7} .spec-table tbody tr:hover{background:#e5e5e5} .spec-table a{color:#0066cc;text-decoration:none;font-weight:600;background:transparent;padding:0;border-radius:0;box-shadow:none} .group-row td{font-weight:700;text-align:center;background:#fff;color:#444} @media(max-width:640px){ .spec-table-wrapper{overflow:visible} .spec-table.is-mobile-table{min-width:100%!important;width:100%!important} .spec-table.is-mobile-table thead{display:none} .spec-table.is-mobile-table tbody, .spec-table.is-mobile-table tr, .spec-table.is-mobile-table td{display:block;width:100%} .spec-table.is-mobile-table tr{margin-bottom:12px;border:1px solid #ddd;background:#fff} .spec-table.is-mobile-table td{display:flex;justify-content:space-between;text-align:right;padding:8px;border:none;border-bottom:1px solid #eee} .spec-table.is-mobile-table td:last-child{border-bottom:none} .spec-table.is-mobile-table td::before{content:attr(data-label);font-weight:700;text-align:left;color:#444;padding-right:10px} .spec-table.is-mobile-table .group-row{display:block} .spec-table.is-mobile-table .group-row td{display:block;text-align:center} } Available Variations and Specifications + SKUMAX.
