KDA 3.3-150-3-DYS-W1

The Bosch Rexroth Indramat KDA 3.3-150-3-DYS-W1 spindle drive from the KDA Spindle Drives series is designed for robust control of main spindles in industrial machinery. As a 3-phase unit, it delivers a rated current of 150 A and operates on a DC Bus Voltage of 300 V, ensuring continuous power delivery and an extensive speed range. With its high stiffness and precise positioning capabilities, the KDA 3.3-150-3-DYS-W1 excels at maintaining accuracy under heavy loads while supporting demanding spindle drive applications.

Incorporating advanced control features, the drive accepts a Speed Command Value via a Digital 16-Bit Parallel interface, enabling fine resolution speed regulation. The Aux. Encoder Input supports both auxiliary and synchronous inputs, meeting AS 35 requirements for high-precision feedback. System integration is facilitated through an Aux. Interface of Serial Interface RS 232 C, providing straightforward connection to higher-level controllers. Forced cooling by a heatsink blower, powered from a 220 VAC AC supply source, maintains optimal thermal conditions and prevents overheating during extended operation. The unit’s compact Design 3 form factor follows the KDA product lineage and aligns with Series 3 specifications for seamless replacement or upgrade.

Designed for compatibility with common automation standards and engineered for durability, the KDA 3.3-150-3-DYS-W1 ensures efficient heat dissipation and uninterrupted performance in harsh environments. Its heatsink blower cooling system extends component life, while the parallel digital command input and synchronous encoder interface offer precise speed control and rapid response. By adhering to Bosch Rexroth Indramat’s rigorous quality measures, this spindle drive enhances process reliability and reduces downtime. Employed in CNC machining, milling, and lathing centers, it provides stable power, high torque density and the precise speed management essential for modern industrial production.
