Bosch Rexroth Indramat KDA 3.3-100-3-DPI-W1 is a high-performance spindle drive from the Bosch Rexroth Indramat manufacturer and part of the KDA Spindle Drives series. It offers exceptional stiffness and precise positioning features, providing reliable continuous power delivery across a broad speed range. Featuring a nominal Rated Current of 100 A and a DC Bus Voltage of 300 V, the drive is engineered for demanding main spindle applications. Its robust 3-design architecture and optimized power electronics ensure stable torque output under fluctuating load conditions.
The KDA 3.3-100-3-DPI-W1 integrates advanced thermal management with an AC Supply Source for Heatsink Blower rated at 220 VAC and a Forced Cooled by Heatsink Blower scheme to maintain consistent operating temperatures. An Aux. Encoder Input supports both spindle and secondary motor feedback, while the Aux. Interface provides an Incremental Encoder Output for high-resolution position monitoring. Speed regulation leverages a Speed Command Value input in a Digital 16-Bit Parallel format, enabling microsecond-level response and smooth acceleration profiles. The compact Product design and standardized mounting dimensions simplify retrofit into existing machine tool installations.
Engineers benefit from seamless integration via familiar electrical and encoder interfaces, reducing installation time and minimising downtime. The combination of efficient cooling, high current capacity, and precision control enhances system reliability for continuous-duty operations. Ideal for CNC machining centers and automated production lines, the KDA 3.3-100-3-DPI-W1 delivers the performance and durability required in advanced manufacturing environments.
