KDA 3.3-150-3-L0D-U1

The Bosch Rexroth Indramat KDA 3.3-150-3-L0D-U1 from the KDA Spindle Drives series is engineered as a high-stiffness, precision spindle solution. This KDA product features a Design 3 frame and supports a Rated Current of 150 A with a DC Bus Voltage of 300 V for robust continuous power delivery. Speed command is handled via the SERCOS - Interface speed command value protocol, ensuring seamless integration with digital motion controls. As part of the family, the drive’s internal Series 3 architecture enables consistent performance across spindle applications.

Internal cooling is achieved through a forced-cooled heatsink blower that operates from a dedicated 115 VAC AC supply source, maintaining optimal thermal conditions under heavy loads. The drive offers a Position Command Value Digital 16-Bit Parallel auxiliary interface for high-resolution position setpoints. For streamlined integration, the unit ships without an auxiliary encoder input, simplifying wiring when external feedback is not required. The combination of these interfaces and cooling features ensures reliable operation in demanding machining environments.

Designed to excel in high-precision milling and turning centers, the KDA 3.3-150-3-L0D-U1 spindle drive delivers an extensive speed range and dynamic positioning performance. Its rigid construction and advanced digital command interfaces make it well suited for applications requiring tight tolerances, rapid acceleration, and sustained continuous power. This spindle drive represents a versatile and dependable choice for modern CNC machining platforms.
