M740A1038 | Honeywell Actionator Motor 120 V AC 60 sec Full-Stroke for Damper/Valve Control

Honeywell · Motors & Motion

Description  The Honeywell M740A1038 is a high-torque “Actionator” motor/actuator rated for 120 V AC at 60 Hz (40 VA) with a 60-second full-stroke time. Designed for direct-coupled damper or valve applications, it provides reliable rotary motion in industrial HVAC and control systems. This unit is discontinued by the manufacturer, making it a specialist choice for legacy equipment replacement.     Technical Specifications  Condition New/Never Used Surplus Brand Honeywell Category Motors / Gearbox / Clutch Part Number M740A1038 Subcategory Motor / Actuator Power Supply 120 V AC, 60 Hz Power Consumption 40 VA Full-Stroke Time 60 seconds (180° rotation) Torque Output High torque, suitable for damper/valve control Drive Type Worm gear with adjustable crank arm Holding Brake Internal disc brake, self-locking when unpowered Housing Material Die-cast aluminum Shaft Seal Buna-N O-ring Mounting Direct-coupled or linkage via crank arm Operating Temperature -20 °C to +65 °C (-4 °F to +149 °F) Duty Cycle 70% typical Weight 15.00 lbs Product Status Discontinued by Manufacturer     Information About M740A1038 The M740A1038 belongs to Honeywell’s M740A series of “Actionator” motors/actuators, intended for positioning dampers, butterfly valves, slip-stem valves and other mechanical control elements. The series features die-cast aluminum enclosures, sealed shafts (Buna-N O-rings), internal disc brakes to hold position when power is removed, and adjustable crank-arms for linkage connection. Within the M740A family, the “1038” variant is specified for 120 V AC applications with a timing of approximately 60 seconds per 180° rotation (standard model timing), and no auxiliary switches or slide-wire feedback by default. The unit is designed for demanding industrial installations where long-life, stable positioning and rugged construction are required. Key Features: 120 V AC Power Supply: Compatible with standard single-phase control circuits. 60-Second Full-Stroke Time: Provides smooth 180° rotation in one minute for controlled movement. Internal Holding Brake: Maintains shaft position when power is removed for safety and precision. Heavy-Duty Worm Gear Mechanism: Ensures long-life and high torque for demanding applications. Rugged Aluminum Housing: Provides protection and durability in industrial environments. Oil-Resistant Shaft Seals: Buna-N O-rings prevent contamination and wear. Adjustable Crank Arm: Allows customized linkage setups for valves and dampers. High Torque Output: Designed to drive large or high-friction control components. Easy Field Installation: Suitable for direct coupling or linkage mounting. Legacy Model Support: Compatible with existing Honeywell control systems still in service. The M740A1038 delivers the power, precision, and reliability required for industrial automation and HVAC control applications.
