KDA 3.3-150-3-DQI-U1

KDA 3.3-150-3-DQI-U1, manufactured by Bosch Rexroth Indramat, is part of the robust KDA Spindle Drives series designed for demanding CNC and machining center applications. This main spindle drive delivers a continuous Rated Current of 150 A through a DC Bus Voltage of 300 V, ensuring high torque and stiffness across the entire speed range. Equipped with a Design-optimized housing and built on the proven Product: KDA architecture, it combines rigidity with advanced positioning capabilities. High dynamic response and precision control make it ideal for modern, high-speed spindles.

Featuring a Cooling system that is Forced Cooled by Heatsink Blower powered by an AC Supply Source for Heatsink Blower of 115 VAC, the drive maintains optimal thermal performance under continuous load. Motion commands are processed via a Speed Command Value interface of Digital 16-Bit Parallel, while feedback is managed through an Aux. Encoder Input for 1 V Sinusoidal signals. A secondary Aux. Interface provides an Incremental Encoder Output for real-time position verification. The encapsulated construction and standardized Series permitting plug-and-play integration reduce installation time and ensure consistent performance across units.

Integration into existing control architectures is seamless, and the drive’s forced-cooling arrangement enhances reliability by actively removing heat from power stages. Bosch Rexroth Indramat’s stringent quality controls guarantee long service life with minimal downtime, while the modular design supports easy maintenance and upgrades. Engineers benefit from precise spindle regulation, making the KDA 3.3-150-3-DQI-U1 an outstanding choice for high-precision machining, milling centers, and dynamic routing applications.
