KDA 3.1-050-3-LPI-W1

The Bosch Rexroth Indramat KDA 3.1-050-3-LPI-W1 from the KDA Spindle Drives series integrates the manufacturer Bosch Rexroth Indramat's precision engineering with robust industrial performance. Featuring a rated current of 50 A and a DC Bus Voltage of 300 V, this main spindle drive delivers continuous power across an extensive speed range. The drive’s Speed Command Value via SERCOS - Interface ensures high-resolution motion control and seamless communication in complex machine tools. Designed as Product KDA with a Design 1 housing, it offers high stiffness and superior positioning capability for demanding spindle applications.

With Forced Cooled by Heatsink Blower technology, heat dissipation is maintained by a dedicated AC Supply Source for Heatsink Blower at 220 VAC, ensuring optimal thermal management under continuous loads. The integrated Aux. Encoder Input caters to both spindle and secondary motor feedback, while the Aux. Interface Incremental Encoder Output supports real-time position verification for advanced CNC processes. These interfaces, combined with the robust KDA architecture, help maintain precise speed and torque regulation even under rapid load changes.

Built for industrial environments, the KDA 3.1-050-3-LPI-W1 spindle drive excels in applications requiring high reliability, repeatable accuracy, and fast response. Its forced-air cooling system and reinforced housing minimize downtime by protecting internal components from thermal stress. Whether installed in milling, grinding, or multi-axis turning centers, this KDA series drive provides consistent performance and long-term operational stability.
