Product Details

Danaher Motion 401-34438-00 is an original brushless servo motor and low inertia motor, designed to pair with Danaher Motion legacy servo drive systems for high dynamic motion control. This servo drive motor delivers fast acceleration and deceleration thanks to its low-inertia rotor structure, making it ideal for cyclic, high-speed positioning tasks. Integrated with high-resolution encoder feedback and optional 24 V holding brake, it feeds precise position and velocity data back to the servo amplifier to maintain tight closed-loop regulation. As an obsolete original spare part, it is widely selected as a drop-in replacement when the existing motor fails on aging production machinery. Direct replacement helps retain the original machine control program, avoids costly system upgrades, and greatly cuts equipment downtime. Built with industrial-grade winding, reinforced rotor and sealed housing, this brushless servo motor sustains continuous heavy-duty operation in demanding factory environments and offers reliable, repeatable motion output for automated production equipment.
