KDA 3.1-050-3-DP0-W1

The Bosch Rexroth Indramat KDA 3.1-050-3-DP0-W1 is a high-performance spindle drive from the KDA Spindle Drives series by Bosch Rexroth Indramat. It features a Rated Current of 50 A and a DC Bus Voltage of 300 V to support demanding machining operations. Engineered for exceptional stiffness and rapid positioning features, it delivers a broad speed range with continuous power output, making it ideal for precision spindles. Robust construction and digital control ensure consistent performance across the entire operating envelope.

The drive’s technical foundation includes an AC Supply Source for Heatsink Blower of 220 VAC and a Cooling system of forced cooled by heatsink blower to maintain thermal stability under heavy loads. A Speed Command Value interface provides Digital 16-Bit Parallel input for deterministic speed regulation. Feedback options are expanded with an Aux. Encoder Input “with for spindle or second motor feedback”, while the Aux. Interface is specified as without to streamline configuration. The unit’s Design is classified as 1 in the KDA product family, with a Product identifier of KDA and belonging to Series 3. All components are housed in a rugged enclosure optimized for industrial environments, backed by precise Bosch Rexroth Indramat quality controls.

Integrators benefit from the drive’s plug-and-play architecture and standardized digital command protocol, which simplify commissioning and reduce wiring complexity. The forced-cooling arrangement and high-rated components guarantee reliable operation in continuous-cycle CNC and automated milling applications. With tight speed control, robust thermal management, and precise encoder feedback support, the KDA 3.1-050-3-DP0-W1 is engineered to deliver consistent spindle performance in high-precision machining centers.
