KDA 3.3-050-3-DQI-W1

The Bosch Rexroth Indramat KDA 3.3-050-3-DQI-W1 from the KDA Spindle Drives series, manufactured by Bosch Rexroth Indramat, delivers precision spindle control with a Rated Current of 50 A and a DC Bus Voltage of 300 V. This Design 3, Product KDA module employs a Cooling method that is Forced Cooled by Heatsink Blower and supports a Speed Command Value via a Digital 16-Bit Parallel interface. Configured in Series 3, it ensures seamless integration into high-performance CNC systems while maintaining optimal thermal management. The drive’s robust construction and tailored electronics cater to demanding machining environments.

Equipped with an AC Supply Source for Heatsink Blower rated at 220 VAC, the drive sustains continuous power delivery under peak load conditions. A dedicated Aux. Encoder Input for 1V Sinusoidal signals and an Aux. Interface featuring an Incremental Encoder Output allow synchronized feedback and contouring precision. The drive maintains continuous power output across its extensive speed range, supporting rapid acceleration and deceleration cycles under varying loads. Its high-stiffness design and precise digital control loops ensure consistent torque delivery and positioning accuracy throughout operation.

With its forced-air convective cooling and modular design, the KDA 3.3-050-3-DQI-W1 spindle drive minimizes downtime and simplifies maintenance procedures. Designed for integration into machining centers, mill-turn lathes, and automated tool grinders, this drive provides the reliability and accuracy required for next-generation manufacturing applications. Its robust components and streamlined integration process minimize maintenance requirements, ensuring long-term operational efficiency.
