The Bosch Rexroth Indramat KDA 2.1-100-3-LYI-U1 spindle drive is part of the KDA Spindle Drives series and is engineered by Bosch Rexroth Indramat for demanding machine tool applications. This main spindle drive delivers a rated current of 100 A and operates on a DC Bus Voltage of 300 V, ensuring robust power delivery. Designed to provide high stiffness, precise positioning features, and an extensive speed range, it excels in continuous power spindle control tasks.
Incorporating advanced technical features, the KDA 2.1-100-3-LYI-U1 unit employs a forced (heatsink blower) cooling method with a dedicated heatsink blower powered at 115 VAC to maintain optimal operating temperatures under heavy load. It supports a SERCOS speed command interface for real-time motion control and synchronization. The drive offers an auxiliary encoder input with both auxiliary and synchronous modes, and an incremental encoder output interface, enabling seamless integration with high-precision feedback systems. The product code is KDA, with a series number of 2 and design number 1.
Additional features include versatile encoder compatibility and a reliable heatsink blower supply, enhancing durability in continuous operation scenarios. The SERCOS interface ensures compatibility with industry-standard automation networks, while the incremental encoder output supports precise speed and position feedback. In industrial environments, the forced cooling strategy maximizes efficiency and extends component life, reducing downtime. Overall, the KDA 2.1-100-3-LYI-U1 provides precise spindle control, high torque stiffness, and reliable performance for machining centers, CNC lathes, and other critical manufacturing applications.
