KDA 3.3-150-3-DYI-U1

The Bosch Rexroth Indramat KDA 3.3-150-3-DYI-U1 from the KDA Spindle Drives series delivers robust spindle control with a Rated Current of 150 A and a DC Bus Voltage of 300 V for sustained high-power applications. Leveraging a precision-engineered Design 3 architecture and the proven KDA product platform, this drive ensures exceptional rigidity and dynamic response. Its extensive speed range is managed via a Digital 16-Bit Parallel Speed Command Value, offering submicron positioning accuracy and rapid acceleration profiles. Integrated monitoring and fault diagnostics streamline maintenance and maximise uptime in demanding manufacturing environments.

Operating reliability is further enhanced by a dedicated 115 VAC AC Supply Source for Heatsink Blower, which guarantees consistent thermal management under peak load. The drive’s Forced Cooled by Heatsink Blower cooling arrangement maintains optimal junction temperatures, even during continuous heavy-duty cycles. Auxiliary feedback is accommodated through With Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A) on the Aux. Encoder Input, while the Aux. Interface provides incremental encoder output for tight loop control. These interfaces simplify integration with multi-axis CNC systems and advanced motion controllers.

Compact yet powerful, the KDA 3.3-150-3-DYI-U1 embodies Bosch Rexroth Indramat’s commitment to precision spindle solutions. Its consistent mechanical footprint across the Series 3 family reduces engineering complexity during retrofits and new machine builds. Whether applied in high-speed machining centers or precision turning lathes, this main spindle drive delivers the performance, flexibility, and reliability required for next-generation manufacturing.
