KDA 3.3-050-3-DPI-W1

The Bosch Rexroth Indramat KDA 3.3-050-3-DPI-W1 drive from the Bosch Rexroth Indramat KDA Spindle Drives series delivers high-stiffness spindle control for demanding machining operations. It combines precision positioning features with an extensive speed range capable of continuous power output, ensuring smooth acceleration and deceleration profiles in heavy metal removal tasks. With a compact footprint and rugged build, the unit withstands harsh shop-floor conditions while maintaining dynamic response and control accuracy. Designed for seamless CNC integration, it meets stringent industrial standards for repeatability and performance.

Engineered around a DC Bus Voltage of 300 V and a continuous Rated Current of 50 A, this spindle drive provides stable torque across its entire speed envelope. Thermal management is handled by a Cooling system that is Forced Cooled by Heatsink Blower, supplied by an AC Supply Source for Heatsink Blower of 220 VAC to dissipate heat during prolonged high-load operation. Control and feedback channels include a Speed Command Value via a Digital 16-Bit Parallel interface, an Aux. Encoder Input for spindle or secondary motor feedback, and an Aux. Interface offering a Incremental Encoder Output for precise position monitoring. The module’s Design type 3 enclosure and robust electronics ensure reliable performance in vibration-prone environments.

The KDA 3.3-050-3-DPI-W1’s modular architecture and standardized connectivity accelerate integration into existing CNC systems and automation platforms. Its high overload tolerance, active blower cooling, and sturdy construction deliver long-term reliability with minimal maintenance downtime. Ideal for high-precision milling, turning centers, and grinding applications, this spindle drive enhances throughput, surface finish quality, and overall machine tool efficiency.
