Product Description:

The KDA 2.1-150-3-DQS-U1 spindle drive, built by Bosch Rexroth Indramat, sits in the KDA Spindle Drives lineup and stays busy powering all sorts of tool movements in industrial machinery. With a solid rated output current of 150 A and support for input voltages at 400/480 V AC, this drive pushes through long shifts without losing strength. Size-wise, weight comes to about 60 kg, which means this isn’t anything flimsy. It hangs onto panel mounting without shaking loose, and the IP20 protection blocks out most dust that shows up around cabinets.

This model can handle both synchronous and asynchronous servo motors, which adds some flexibility for setups using varied motion systems. Short bursts can shoot the current up to 3x rated, so a tool starts strong or powers through a jam if needed. There’s built-in fan cooling, which sends air through the housing and does its part to keep temperature swings from causing trouble. With SERCOS, analog/digital options, and fieldbus choices for interfacing, this drive works with control systems that change as operations grow or upgrade. Control voltage ticks in at 24 V DC, a usual number that suits factory panels and doesn’t slow down installation.

A string of specs—dimensions at 410 x 345 x 615 mm, sealed connections, and the dual-axis design—help the KDA 2.1-150-3-DQS-U1 fit tightly alongside bigger and smaller equipment. Jobs in heavy automation, grinders, or large machining centers gain steady spindle motion with this drive kept in place. Tight panel installs or speedy retrofits go easy here because every connector stays well organized. When setups demand reliable, repeated movement all day, and error-checking that won’t get lost in vibration or dust, this unit keeps the routine going and resists the stress, shift after shift.
