KDA 3.2-050-3-API-U1

The Bosch Rexroth Indramat KDA 3.2-050-3-API-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat provides exceptional power delivery with a Rated Current of 50 A and a DC Bus Voltage of 300 V. This main spindle drive is optimized for continuous high-torque performance and precise speed control, leveraging an Analog +/– 10V Speed Command Value interface for seamless integration into CNC and milling applications. Its robust design ensures minimal electrical noise and superior dynamic response, while the compact housing reduces panel space requirements. The drive is engineered for straightforward retrofitting in existing systems and modular expansion in new installations.

The thermal management strategy relies on Cooling: Forced Cooled by Heatsink Blower technology driven by an AC Supply Source for Heatsink Blower: 115 VAC, ensuring consistent temperature regulation even under sustained heavy loads. Feedback and synchronization are handled via the Aux. Encoder Input: With for Spindle or Second Motor Feedback channel and the Aux. Interface: Incremental Encoder Output, which together deliver high-resolution positional data and rapid response to control loop corrections. The unit’s internal architecture adheres to a Design: 2 standard within the KDA family, while the Product: KDA model designation and Series: 3 iteration reflect incremental enhancements in power density and reliability. All components are selected to withstand demanding manufacturing environments, and the drive includes built-in diagnostics for simplified troubleshooting and preventive maintenance.

Engineered for high stiffness and extensive speed range under continuous power, this spindle drive excels in high-precision machining and dynamic positioning tasks. The forced-air heatsink blower and encoder connectivity enable stable operation from low-speed indexing to high-speed spindling without torque ripple. Overall, the KDA 3.2-050-3-API-U1 sets a benchmark for spindle drive solutions where rigidity, thermal stability, and precise control are paramount.
