KDA 3.3-050-3-L0S-U1

KDA 3.3-050-3-L0S-U1, Bosch Rexroth Indramat, KDA Spindle Drives delivers a high-performance spindle drive designed for precision machining centers and demanding industrial spindles. This main spindle drive leverages a robust construction and advanced control algorithms to provide a continuous Rated Current of 50 A and a stable DC Bus Voltage of 300 V. The drive’s integrated power stage ensures rapid response and maintains torque consistency across a broad speed range. Optimized for stiffness and dynamic accuracy, it accelerates throughput without sacrificing position control.

Equipped with a dedicated AC Supply Source for Heatsink Blower of 115 VAC, the unit guarantees effective thermal management via its Forced Cooled by Heatsink Blower system. A flexible Aux. Interface featuring Serial Interface RS 232 C enables seamless parameter tuning and diagnostic access. Speed references are communicated through the industry-standard Speed Command Value of SERCOS - Interface, while the Aux. Encoder Input is provisioned as Without to simplify installation in standardized feedback architectures. The drive adheres to a Design classification of 3, aligning with the modular Product family structure of the Series level 3 devices.

Integration into CNC and motion-control networks is straightforward, with the drive’s compact footprint and standardized connections reducing panel space and wiring complexity. The forced-heatsink blower arrangement enhances component longevity, maintaining optimal junction temperatures under sustained loads. Ideal for applications requiring high stiffness, extended speed ranges, and precise positioning, the KDA 3.3-050-3-L0S-U1 ensures reliability and performance in high-demand industrial spindles and machining centers.
