The Bosch Rexroth Indramat KDA 3.1-050-3-LYS-W1 spindle drive is a member of the KDA Spindle Drives series, engineered by Bosch Rexroth Indramat for precision motion control in machine tool applications. It delivers a Rated Current of 50 A and operates at a DC Bus Voltage of 300 V, offering a broad speed range with continuous power output. Designed for high stiffness and accurate positioning, this main spindle drive excels in demanding environments requiring stable torque delivery and rapid dynamic response.



Incorporating an Auxiliary Interface of RS-232C and a Speed Command Interface via SERCOS, the KDA 3.1-050-3-LYS-W1 ensures seamless integration with modern CNC controllers. The drive accepts an Encoder Input Type of both auxiliary and synchronous signals, enabling precise feedback and closed-loop control. Cooling is managed through a forced air (heatsink blower) system, maintaining optimal operating temperatures under sustained loads. Such robust thermal management safeguards performance and extends service life, even in continuous duty cycles.



Additional features include a dedicated Blower Supply Voltage of 220 VAC and a modular Design rating of 1, reflecting the product family’s versatile scalability. As part of the KDA product family, this spindle drive benefits from standardized components and streamlined maintenance procedures. Its compatibility with high-speed SERCOS networks enhances system efficiency and reduces wiring complexity. By delivering reliable torque control, efficient cooling, and comprehensive interface options, the KDA 3.1-050-3-LYS-W1 drive offers substantial advantages in industrial spindle applications, boosting productivity and minimizing downtime.
