The KDA 3.3-100-3-LYI-W1 from Bosch Rexroth Indramat is a precision spindle drive within the KDA Spindle Drives series. This design leverages Bosch Rexroth’s expertise in automation to deliver dependable performance. The unit is classified as Series 3, Design 3, offering a robust architecture optimized for industrial applications. With a DC bus voltage rating of 300 V and a rated current of 100 A, it sets a high bar for spindle power delivery.
Featuring a Speed command interface via SERCOS, the drive ensures deterministic motion control with minimal latency. Feedback precision is enhanced by the Auxiliary encoder interface providing an Incremental encoder output. Thermal management relies on a Forced air (heatsink blower) cooling method, with the Heatsink blower supply rated at 220 VAC to sustain continuous operation. As a dedicated Product of the KDA family, it integrates power electronics and control modules into a compact form factor. The interplay of these specifications guarantees stable torque and rapid response through the entire speed range.
Engineers will appreciate the straightforward integration of this drive into existing motion networks via its standard SERCOS interface and encoder feedback loop. The combination of forced-air cooling and rugged Series 3, Design 3 construction ensures high reliability and long service intervals under demanding workloads. Ideal for precision milling, turning, and grinding machinery, the KDA 3.3-100-3-LYI-W1 spindle drive delivers consistent performance and reduced maintenance overhead.
