KDA 3.2-050-3-AQI-W1

The Bosch Rexroth Indramat KDA 3.2-050-3-AQI-W1 from the KDA Spindle Drives series delivers precision spindle performance with a Rated Current of 50 A and a DC Bus Voltage of 300 V. This Product KDA drive, designated Design 2 and series 3, incorporates a Cooling: Forced Cooled by Heatsink Blower system powered by a AC Supply Source for Heatsink Blower of 220 VAC to maintain optimal thermal conditions. A versatile Speed Command Value: Analog +/- 10V interface allows seamless integration with legacy speed control systems, while the Aux. Interface: Incremental Encoder Output and Aux. Encoder Input for 1V Sinusoidal Enc. provide high‐resolution feedback for closed‐loop control. Compact yet robust, the KDA 3.2-050-3-AQI-W1 offers consistent performance across demanding spindle applications.

Engineered for high stiffness and precise positioning, the KDA Main Spindle Drive supports extensive speed ranges with continuous power delivery and dynamic torque response. The integrated heatsink blower ensures stable operation even under peak loads, and the three‐phase power electronics deliver smooth current regulation at 50 A rated output. With forced cooling and advanced thermal management, this drive maintains performance in ambient conditions that challenge conventional spindle controllers. The incremental encoder interface further enhances motion accuracy, minimizing overshoot and drift during rapid acceleration and deceleration cycles.

Ideal for CNC machining centers, grinding spindles, and high-speed milling applications, the Bosch Rexroth Indramat KDA series drive simplifies commissioning with familiar analog speed setpoints and industry-standard encoder signals. Its rugged construction and standardized mounting footprint facilitate straightforward replacement and retrofitting in existing machine tools. Whether paired with synchronous or asynchronous spindles, the KDA 3.2-050-3-AQI-W1 delivers reliable, high‐precision motion control for the most demanding manufacturing environments.
