KDA 3.3-050-3-DYI-W1

KDA 3.3-050-3-DYI-W1, Bosch Rexroth Indramat, KDA Spindle Drives series adds a powerful main spindle drive optimized for precision machining. With a Rated Current of 50 A and a DC Bus Voltage of 300 V, the KDA 3.3-050-3-DYI-W1 delivers a robust continuous power profile. It features high stiffness and excellent dynamic response to support demanding positioning tasks and wide speed ranges. Built-in digital control and a compact footprint ensure seamless integration into existing CNC frameworks.

The drive’s thermal management is handled via a Forced Cooled by Heatsink Blower system, powered from an AC Supply Source for Heatsink Blower of 220 VAC. Commanded through a Digital 16-Bit Parallel Speed Command Value, it achieves high-resolution speed regulation with minimal latency. Auxiliary feedback is supported by an Aux. Encoder Input with auxiliary and synchronous inputs, while motion data flows through an Aux. Interface offering Incremental Encoder Output. The rugged Design 3 enclosure and modular Product KDA architecture simplify maintenance and field servicing.

Engineers benefit from the spindle drive’s reliability and ease of commissioning: pre-calibrated parameters interface directly with Bosch Rexroth Indramat control systems, reducing setup time. The sturdy cooling blower and reinforced encoder connections guarantee stable operation under continuous loads, minimizing downtime in automated production lines. Ideal for high-precision milling, grinding, and turning applications, the KDA 3.3-050-3-DYI-W1 pairs performance with proven industrial dependability.
