KDA 3.3-100-3-LY0-U1

The KDA 3.3-100-3-LY0-U1, Bosch Rexroth Indramat, KDA Spindle Drives form a high-performance spindle drive platform engineered for precision and dynamic response. The drive leverages a robust 3-phase design with an integrated heatsink blower delivering forced cooling to maintain thermal stability under heavy loads. Its compact housing blends rugged construction with accessibility, ensuring seamless integration into existing CNC and machining centers. Advanced positioning features and a wide speed range optimize toolpath accuracy, making the system ideal for demanding milling and turning applications.

Detailed specifications underpin its versatility: the drive draws its cooling power from a 115 VAC heatsink blower (AC Supply Source for Heatsink Blower) and sustains a continuous Rated Current of 100 A. A 300 V DC Bus Voltage link feeds the power stage, while the SERCOS - Interface handles the Speed Command Value for deterministic motion control. Auxiliary synchronization is provided via the Aux. Encoder Input with synchronous and auxiliary channels, and a pared-back topology uses Aux. Interface provisions as specified. The Design 3 architecture and compact Product KDA form factor balance power density with serviceability.

Integration into automated production lines is streamlined by the standardized SERCOS interface, enabling real-time communication with PLCs and CNC controllers for coordinated multi-axis operations. The forced-cooled heatsink blower ensures reliable operation over extended duty cycles, reducing overheating risks and maintenance intervals. With its combination of high stiffness, precise position control, and broad speed range, the KDA 3.3-100-3-LY0-U1 spindle drive delivers consistent, reliable performance in high-speed machining, aerospace components manufacture, and precision tooling environments.
