KDA 3.1-150-3-API-U1

The Bosch Rexroth Indramat KDA 3.1-150-3-API-U1 main spindle drive is part of the KDA Spindle Drives series. Key specifications include a Rated Current: 150 A, a DC Bus Voltage: 300 V, and Cooling: Forced Cooled by Heatsink Blower. Designed for precise power conversion, this spindle drive controls main spindles in industrial machining centers, delivering enhanced torque output and accurate speed regulation to support high-performance manufacturing processes.

Featuring a robust DC bus voltage of 300 V and a continuous rated current of 150 A, this drive ensures uninterrupted power support across a wide speed range. Thermal management is handled by an AC Supply Source for Heatsink Blower: 115 VAC, providing forced cooling to maintain stable temperatures under heavy operational loads. It integrates an Aux. Encoder Input for spindle or secondary motor feedback and an Aux. Interface: Incremental Encoder Output for precise position sensing. The Speed Command Value: Analog +/- 10V input facilitates smooth synchronization with PLCs and automation controllers, while the Design: 1 configuration tailors the drive specifically for spindle applications.

This spindle drive’s compatibility with future automation technologies is underpinned by its versatile feedback interfaces and standard analog command protocols. The forced-cooled heatsink blower enhances durability, preserving performance in continuous-duty scenarios and extending service life through effective thermal regulation. By combining these technical features, the Bosch Rexroth Indramat KDA 3.1-150-3-API-U1 achieves superior efficiency in power conversion and spindle control precision. In industrial environments, it offers reliable integration, exceptional thermal stability, and consistent performance, making it an ideal solution for precision machining and automated production lines.
