KDA 2.1-100-3-D0D-U1

The Bosch Rexroth Indramat KDA 2.1-100-3-D0D-U1 from the KDA Spindle Drives series is designed for demanding main spindle applications and delivers a Rated Current of 100 A with a stable DC Bus Voltage of 300 V. This drive, designated as Product KDA of Design 1 and Series 2, ensures consistent power delivery across high-torque regimes. Built to precise technical standards, it integrates seamlessly into modern machine tool architectures without external modifications. With a compact footprint and robust construction, it supports precision machining centers and high-speed milling spindles alike.

Reliability is reinforced through a dedicated cooling infrastructure: the Cooling Forced Cooled by Heatsink Blower system operates on an AC Supply Source for Heatsink Blower of 115 VAC, ensuring optimal thermal management under continuous load. Control inputs remain straightforward thanks to the Aux. Interface Position Command Value Digital 16-Bit Parallel and a Speed Command Value Digital 16-Bit Parallel, providing high-resolution feedback for motion controllers. For installations where encoder feedback is unnecessary, the unit offers an Aux. Encoder Input Without option to simplify wiring and reduce system complexity. All interfaces are encapsulated within rugged housings to maintain IP ratings and preserve long-term operational integrity.

Engineered with high stiffness and extensive speed range in mind, the KDA 2.1-100-3-D0D-U1 spindle drive excels in positioning accuracy and dynamic response. Continuous power delivery combined with forced air cooling enables non-stop production cycles, minimizing downtime in high-volume manufacturing. Whether used in aerospace parts milling or precision tooling, this drive offers the technical performance required for advanced spindle control.
