KDA 3.3-100-3-AQD-U1

The Bosch Rexroth Indramat KDA 3.3-100-3-AQD-U1 spindle drive from the KDA Spindle Drives line by Bosch Rexroth Indramat delivers high stiffness and precision positioning across an extensive speed range. Engineered for demanding main spindle applications, it provides continuous power handling with robust mechanical design and integrated control features. Its construction supports rapid acceleration and stable operation under variable loads, ensuring consistent machining accuracy. The drive’s proven architecture simplifies adoption into both new and retrofit machining centers.

Equipped with a Rated Current of 100 A and a DC Bus Voltage of 300 V, this unit maintains sustained torque output even under peak demands. Thermal management is handled via Forced Cooled by Heatsink Blower circuitry, powered by an AC Supply Source for Heatsink Blower of 115 VAC, safeguarding components during extended cycles. Precision feedback is supported through With Aux. Encoder Input for 1V Sinusoidal Enc. and a Position Command Value Digital 16-Bit Parallel Aux. Interface, while velocity setpoints are fed via an Analog +/- 10V Speed Command Value input. The drive adheres to a rugged Design 3 topology within the Product KDA, Series 3 envelope for seamless cabinet integration.

Integration into multi-axis machining systems is accelerated by its standardized electrical and encoder interfaces, reducing cabinet wiring and commissioning time. Reliability is enhanced through forced cooling and industrial-grade components that minimize thermal drift and extend mean time between failures. Ideal for high-precision milling, turning, and grinding centers, the KDA 3.3-100-3-AQD-U1 brings consistent performance and straightforward system interoperability to advanced manufacturing environments.
