KDA 3.3-050-3-AQI-W1

The Bosch Rexroth Indramat KDA 3.3-050-3-AQI-W1 from the KDA Spindle Drives series is a high-performance main spindle drive designed for precision motion control in demanding industrial applications. With a Rated Current of 50 A and a DC Bus Voltage of 300 V, this drive delivers continuous power and extensive speed range to maintain consistent torque and stiffness under varying loads. The drive’s primary function is to accurately regulate spindle speed and positioning, making it ideal for CNC machining centers, milling machines, and other high-precision equipment.

Offering advanced technical capabilities, the KDA 3.3-050-3-AQI-W1 features an Analog +/- 10V Speed Command Value for seamless integration with standard control systems. It is Forced Cooled by Heatsink Blower, ensuring optimal thermal management during extended operation. The drive includes an Aux. Encoder Input for 1V Sinusoidal Enc. and an Incremental Encoder Output as its auxiliary interface, providing high-resolution feedback for closed-loop control. The design configuration (Design: 3, Series: 3) reflects the latest generation of KDA products, engineered for reliability and precision.

Additional features underscore the unit’s compatibility and efficiency: it accepts a 220 VAC supply for the heatsink blower and is designed for easy integration into existing automation setups. The forced cooling mechanism enhances durability by maintaining stable operating temperatures, reducing thermal stress on internal components. By leveraging robust encoder interfaces and precise analog speed commands, the KDA drive minimizes latency and maximizes dynamic response. In industrial environments, this spindle drive offers superior stiffness, repeatable positioning, and efficient power utilization, translating into shorter cycle times, reduced downtime, and enhanced overall productivity.
