KDA 3.2-150-3-DY0-U1

The Bosch Rexroth Indramat KDA 3.2-150-3-DY0-U1 from the KDA Spindle Drives series combines high-performance spindle control with robust industrial design. Featuring a Rated Current of 150 A and a DC Bus Voltage of 300 V, this unit delivers continuous power for demanding machining operations. It supports a Digital 16-Bit Parallel Speed Command Value for precise velocity regulation and relies on Forced Cooled by Heatsink Blower technology to maintain optimal thermal stability. The drive’s auxiliary power demands are efficiently met by an AC Supply Source for Heatsink Blower rated at 115 VAC.

Engineered as a Product of Design 2, the KDA Main Spindle Drive includes an Aux. Encoder Input with both auxiliary and synchronous inputs (compliant with AS 35 standards) for integrated feedback loop applications. Although it comes Without any auxiliary interface, its seamless integration into CNC systems is assured through standard connection protocols. The drive’s Series 3 heritage underpins its proven reliability, while a rugged heat sink blower assembly ensures long-term operation under cyclical loading. Precision components and tight manufacturing tolerances contribute to a consistent thermal profile and reduced maintenance intervals.

Ideal for machine tools requiring high stiffness, advanced positioning features, and an extensive speed range with continuous power output, the KDA 3.2-150-3-DY0-U1 excels in turning, milling, and grinding spindle applications. Its compact footprint and forced-cooling scheme support high-duty cycles, minimizing thermal drift and maximizing spindle uptime. This spindle drive represents a scalable, high-density solution for advanced manufacturing environments.
