KDA 3.3-050-3-A0I-U1

The KDA 3.3-050-3-A0I-U1, Bosch Rexroth Indramat, KDA Spindle Drives is a main spindle drive engineered for high-stiffness machining applications. It features advanced positioning functions and an extensive speed range with continuous power output, making it ideal for demanding spindle control. Built around robust power electronics, the unit supports precise torque regulation and dynamic response under variable load. Its modular design ensures straightforward integration into CNC systems and machine tool platforms.

Incorporating a DC Bus Voltage of 300 V and a continuous Rated Current of 50 A, this spindle drive delivers consistent performance across its operating envelope. The 3 topology is paired with forced cooling via a heatsink blower, powered by an AC Supply Source for Heatsink Blower at 115 VAC to maintain optimal thermal stability. The drive accepts an Analog +\- 10V Speed Command Value for seamless speed reference input and provides an Aux. Interface with for feedback. Although it ships Without an Aux. Encoder Input port, the integrated interface supports a wide range of external encoders and encoderless control.

Engineered for reliability and low-maintenance operation, the KDA 3.3-050-3-A0I-U1 offers fault-tolerant performance and rapid fault diagnostics via its built-in drive electronics. Its forced-cooling scheme minimizes temperature rise, extending component life under continuous duty. Perfectly suited for high-precision milling spindles or grinding applications, this drive streamlines machine tool integration and elevates overall system uptime.
