Product Details

The Danaher Motion 401-34433-20, also marked as Giddings & Lewis HSM320-B24, is a discontinued high-torque permanent magnet brushless AC servo motor built for legacy CNC and heavy-duty motion control systems. This HSM320-B24 servo motor converts power signals from matched servo amplifiers into stable, powerful rotary motion for heavy feed axes on machine tools and automated production equipment. As a reliable high torque brushless motor, it adopts heavy-duty precision bearings, high-grade rare-earth magnets and integrated high-resolution incremental encoder feedback, capable of sustaining continuous heavy load, frequent acceleration-deceleration cycles and strong vibration in harsh workshop environments. This Giddings & Lewis servo motor serves as a popular OEM replacement spare to restore positioning accuracy and load capacity for ageing machining centers; it is stocked as genuine replacement spare part for industrial motion control systems.

Supported Functions

This servo motor executes closed-loop torque, speed and position control for heavy machine feed axes. The built-in incremental encoder continuously feeds real-time angular position and velocity data back to the servo drive to minimize tracking error. It delivers instant peak torque for rapid traverse and heavy cutting feed while maintaining smooth low-speed rotation. It supports thermal monitoring and fault signal output for overload protection, and can synchronize with other axes to run complex heavy-cutting NC machining programs.

Core Functions

The rugged mechanical construction is engineered for long runtime under cyclic heavy loads. Its native encoder interface ensures seamless communication with original legacy Giddings & Lewis servo drives without extra signal conversion. Standard flange and shaft dimensions support direct drop-in swap for the original motor without major mechanical modification, and it serves as direct drop‑in substitution for existing 401-34433-20 HSM320-B24 servo motors.
