KDA 3.3-050-3-D00-W1

The KDA 3.3-050-3-D00-W1, Bosch Rexroth Indramat, KDA Spindle Drives model excels as a high-performance main spindle drive with built-in stiffness and precision positioning. It delivers an extensive speed range optimized for demanding milling and turning operations, backed by continuous power handling for extended cycle times. This unit’s robust design minimizes mechanical resonance while supporting rapid torque response across the operating band. Engineered for industrial spindles, it ensures consistent output and precise control under variable load conditions.

Designed for seamless integration, the drive operates from a DC Bus Voltage of 300 V and supplies a Rated Current of 50 A for medium-power spindle applications. Cooling is handled by a Forced Cooled by Heatsink Blower arrangement, with an AC Supply Source for Heatsink Blower at 220 VAC to maintain optimal thermal stability. Commanding speed through a Digital 16-Bit Parallel Speed Command Value interface, the unit requires no supplemental analog conversion. Auxiliary connectivity is streamlined: both Aux. Encoder Input and Aux. Interface are marked Without to simplify installation. The drive’s Design category is 3, reflecting the refined KDA family architecture, and it identifies as the core Product in the KDA Series.

Integration is straightforward with standardized mounting and control protocols, reducing commissioning time on CNC spindles. The forced-cooling strategy and ruggedized components enhance reliability in 24/7 machining environments, while the digital speed command enables precise synchronization with external controllers. Ideal for high-precision grinding, drilling, and finishing lines, the KDA 3.3-050-3-D00-W1 delivers consistent performance and long-term operational stability.
