The Bosch Rexroth Indramat KDA 3.3-100-3-LQ0-U1 drive is a high‐performance unit in the KDA Spindle Drives series, engineered by Bosch Rexroth Indramat for precision spindle applications. This main spindle drive delivers a Rated Current of 100 A and operates on a DC Bus Voltage of 300 V, ensuring consistent power delivery across a broad speed range. With its robust design and positioning features, it excels in demanding machining and milling environments where high stiffness and continuous power are critical.
Built around a three‐phase framework designated as Design 3, the KDA 3.3-100-3-LQ0-U1 incorporates a dedicated Aux. Encoder Input supporting 1 V sinusoidal signals for accurate feedback and motion control. Speed commands are managed via a SERCOS – Interface technology, providing real-time communication and ensuring rapid adjustment of spindle velocity. The unit is equipped with an integrated heatsink blower powered by anstrong>AC Supply Source for Heatsink Blower of 115 VAC, offering forced cooling that maintains optimal operating temperatures even under peak load conditions. The absence of an auxiliary interface simplifies integration while focusing on the critical control paths.
Compatibility with standard industrial control systems is enhanced by the drive’s streamlined power architecture and encoder coupling. The forced cooling scheme guarantees thermal stability and prolongs component life, translating to reduced downtime and maintenance costs. Designed specifically for spindle control, the KDA 3.3-100-3-LQ0-U1 achieves exceptional torque consistency and efficient heat dissipation, supporting extended duty cycles without performance degradation. In industrial applications, this spindle drive ensures precise rotational dynamics, improved throughput, and reliable operation, making it an ideal choice for high-precision manufacturing equipment.
