KDA 3.3-050-3-D0I-U1

KDA 3.3-050-3-D0I-U1, Bosch Rexroth Indramat, KDA Spindle Drives deliver robust spindle control in high-performance machine tools. This main spindle drive specializes in high stiffness, precise positioning, and broad speed range applications. Equipped for continuous duty, it supports demanding machining cycles and maintains torque stability under varying loads. The unit’s solid construction and integrated cooling ensure consistent performance across extended production runs.

At the core of this drive lies a DC Bus Voltage of 300 V paired with a Rated Current of 50 A, enabling reliable energy delivery for spindle acceleration and deceleration. Forced cooling via Cooling with a Heatsink Blower driven from an AC Supply Source for Heatsink Blower of 115 VAC removes heat effectively, extending component life. Motion inputs are handled through a Speed Command Value of Digital 16-Bit Parallel, while feedback channels include an Aux. Interface for Incremental Encoder Output. The Aux. Encoder Input is configured Without additional sensors, simplifying installation. The drive’s Design is optimized as type 3, and it belongs to the core Product family KDA.

Seamless integration with Bosch Rexroth Indramat control ecosystems enables coordinated multi-axis operation and reduces commissioning time. The robust thermal management and precision command architecture increase system availability and machining accuracy. Ideal for CNC spindles, grinding heads, and high-speed milling, the KDA 3.3-050-3-D0I-U1 enhances machine reliability and productivity across diverse manufacturing environments.
