KDA 2.1-100-3-DQI-W1

The Bosch Rexroth Indramat KDA 2.1-100-3-DQI-W1 from the KDA Spindle Drives series exemplifies precision engineering and robust performance. Manufactured by Bosch Rexroth Indramat, this main spindle drive delivers a Rated Current of 100 A and a DC Bus Voltage of 300 V to meet demanding machining requirements. With a Design 1 configuration and Product KDA lineage, it ensures seamless integration into existing CNC frameworks. The unit’s Series 2 architecture provides enhanced structural rigidity, stable thermal behavior, and reliable electrical characteristics for continuous operation.

Reliability is further reinforced by an AC Supply Source for Heatsink Blower of 220 VAC that powers the Forced Cooled by Heatsink Blower system, maintaining optimal junction temperature during high-duty cycles. The drive’s Aux. Encoder Input for 1V Sinusoidal Enc. and Incremental Encoder Output interface allow precise feedback loops and minimize latency in motion control applications. A Digital 16-Bit Parallel Speed Command Value offers ultrafine speed resolution and rapid setpoint changes without sacrificing stability. These integrated features combine to reduce overshoot and deliver consistent torque across a broad speed range.

Compact yet rugged, the KDA 2.1-100-3-DQI-W1 spindle drive is engineered for both high-speed and high-stiffness operations. Its modular footprint and standardized mounting dimensions simplify retrofit and new-machine installations. When paired with matching Rexroth control systems, it accelerates commissioning and ensures long-term performance in demanding industrial environments.
