Ingersoll Rand 1841W Reversible Multi-Vane Air Motor | 1841 Series | 1.1 HP | 320 RPM | 45.0 (ft-lbs) Starting Torque | 60.0 (ft-lbs) Stall Torque

Description

Ingersoll Rand 1841W Reversible Multi-Vane Air Motor is engineered to provide dependable pneumatic rotary power for industrial applications requiring substantial output torque, controlled low-speed operation, and bidirectional capability. Delivering 1.10 HP with a free speed of 320 RPM, this 1841 Series air motor features a durable multi-vane design that produces smooth, continuous power delivery for demanding industrial environments. Its reversible configuration enables clockwise and counterclockwise rotation, making it well suited for OEM machinery, conveyors, indexing equipment, material handling systems, industrial processing machinery, and other compressed-air powered applications requiring flexible directional control.The 1841W develops a 45.0 lb-ft starting torque, providing strong breakaway force for starting heavily loaded equipment, and a 60.0 lb-ft stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. This combination of lower operating speed, dependable horsepower, and increased torque makes the motor ideal for demanding industrial applications requiring reliable pneumatic performance and smooth reversing capability.Type: Multi-Vane Air Motor | Series: 1841 Series | Model: 1841W | Rotation: Reversible | Power: 1.10 HP | Free Speed: 320 RPM | Starting Torque: 45.0 lb-ft | Stall Torque: 60.0 lb-ftFeatures:Multi-vane air motor design delivers smooth, dependable pneumatic rotary power.Reversible configuration provides reliable clockwise and counterclockwise operation.1.10 HP output supports demanding industrial pneumatic drive applications.320 RPM free speed is ideal for applications requiring controlled low-speed operation with increased output torque.45.0 lb-ft starting torque helps overcome heavy startup loads efficiently.60.0 lb-ft stall torque provides a manufacturer-published reference for evaluating maximum torque capability.Compact motor design integrates easily into OEM machinery and industrial equipment.Compressed-air operation eliminates the need for electrical power at the motor, making it suitable for facilities utilizing centralized pneumatic systems.Made in USA: Applications:OEM machinery requiring reversible pneumatic rotary power.Industrial conveyors, indexing equipment, and positioning systems.Material handling and processing equipment.Packaging and production machinery.Replacement applications where the published motor specifications match the original equipment.FAQs:Q: Is the Ingersoll Rand 1841W 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 320 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. .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%;display:flex;justify-content:center;align-items:center;position:relative;background:#444;color:#fff;border:0;padding:14px 48px;font-family:”Bai Jamjuree”,Arial,sans-serif;font-size:16px;font-weight:700;text-transform:uppercase;cursor:pointer;text-align:center} .spec-accordion-toggle::after{content:”+”;font-size:22px;position:absolute;right:18px} .spec-accordion.open .spec-accordion-toggle::after{content:””} .spec-accordion-panel{display:none!important;width:100%;padding:16px 0 0} .spec-accordion.open .spec-accordion-panel{display:block!important} .spec-accordion-panel[hidden],.spec-accordion:not(.open) .spec-accordion-panel{display:none!important} .spec-table-wrapper{width:100%;max-width:1200px;margin:0 auto;overflow-x:visible!important;overflow-y:visible} .spec-table{width:100%!important;max-width:1200px;min-width:0!important;margin:0 auto;border-collapse:collapse;table-layout:fixed;font-family:”Montserrat”,Arial,sans-serif;font-size:12px;color:#000} .spec-table th{background:#444;color:#fff;text-transform:uppercase;font-family:”Bai Jamjuree”,Arial,sans-serif;font-weight:700;font-size:11px;padding:8px 5px;border:1px solid #ddd;text-align:center;vertical-align:middle;line-height:1.15;white-space:normal;overflow-wrap:anywhere;word-break:normal} .spec-table td{padding:6px 4px;border:1px solid #eee;text-align:center;vertical-align:middle;line-height:1.15;white-space:normal;overflow-wrap:anywhere;word-break:normal} .spec-table .long-text{white-space:normal} .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} .spec-table a:hover{text-decoration:underline} .group-row td{background:#444;color:#fff;font-family:”Bai Jamjuree”,Arial,sans-serif;font-weight:700;text-transform:none;text-align:center;white-space:normal} @media(max-width:900px) and (min-width:641px){ .spec-table{font-size:10px} .spec-table th{font-size:9px;padding:6px 2px} .spec-table td{padding:5px 2px} } @media(max-width:640px){ .spec-accordion,.spec-table-wrapper,.spec-table{width:100%;max-width:100%} .spec-accordion-toggle{font-size:14px;padding:13px 48px} } .spec-accordion.is-mobile-table .spec-table-wrapper{overflow-x:visible!important;overflow-y:visible} .spec-accordion.is-mobile-table .spec-table{width:100%;max-width:100%;min-width:0!important;border:0} .spec-accordion.is-mobile-table .spec-table thead{display:none!important} .spec-accordion.is-mobile-table .spec-table,.spec-accordion.is-mobile-table .spec-table tbody,.spec-accordion.is-mobile-table .spec-table tr,.spec-accordion.is-mobile-table .spec-table td{display:block;width:100%} .spec-accordion.is-mobile-table .spec-table tr{margin-bottom:14px;border:1px solid #ddd;background:#fff} .spec-accordion.is-mobile-table .spec-table tbody tr:nth-child(even),.spec-accordion.is-mobile-table .spec-table tbody tr:hover{background:#fff} .spec-accordion.is-mobile-table .spec-table th,.spec-accordion.is-mobile-table .spec-table td{white-space:normal!important} .spec-accordion.is-mobile-table .spec-table td{display:flex;justify-content:space-between;gap:14px;text-align:right;border:0;border-bottom:1px solid #eee;padding:10px 12px;font-size:13px;word-break:break-word} .spec-accordion.is-mobile-table .spec-table td::before{content:attr(data-label);font-weight:700;text-transform:uppercase;color:#444;text-align:left;flex:0 0 46%} .spec-accordion.is-mobile-table .spec-table td>a{word-break:break-word;background:transparent} .spec-accordion.is-mobile-table .group-row td{display:block;text-align:center;background:#444;color:#fff;padding:12px} .spec-accordion.is-mobile-table .group-row td::before{content:none} Available Variations and SpecificationsSKUMax.
