KDA 2.1-150-3-L00-W1

The Bosch Rexroth Indramat KDA 2.1-150-3-L00-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision spindle control with a robust design and extensive performance features. This Main Spindle Drive supports a DC Bus Voltage of 300 V and provides a continuous Rated Current of 150 A, ensuring steady power delivery for demanding machining operations. The drive’s integrated speed regulation spans a broad range, facilitated by a native Speed Command Value via SERCOS - Interface, delivering synchronization accuracy and high stiffness. Its form factor, designated as Design 1, is tailored to maintain rigidity and compatibility within standardized cabinet layouts.

Reliability is reinforced through redundant cooling and control interfaces: the heatsink blower operates on a dedicated AC Supply Source for Heatsink Blower of 220 VAC, delivering forced cooling for thermal stability under peak loads. Although both Aux. Encoder Input and Aux. Interface are specified as “Without,” the drive retains full functionality through its primary SERCOS link, simplifying wiring and reducing potential failure points. As a Product KDA unit in Series 2, it employs a precision-engineered heatsink and blower assembly that sustains optimal junction temperatures even during continuous operation. The overall construction supports high torsional rigidity, making it ideal for main spindle duties that demand both dynamic response and consistent torque.

Applications for the KDA 2.1-150-3-L00-W1 embrace high-speed spindles in milling, turning, and grinding platforms where Bosch Rexroth Indramat quality is paramount. Its combination of forced-cooled thermal management and precision SERCOS speed control enables operators to achieve tight tolerances and repeatable positioning cycles. With its straightforward integration and maintenance profile, this spindle drive represents a dependable solution for advanced CNC machinery and precision manufacturing environments.
