KDA 3.3-150-3-AQ0-U1

The Bosch Rexroth Indramat KDA 3.3-150-3-AQ0-U1 from the Bosch Rexroth Indramat KDA Spindle Drives series delivers robust performance in high-precision machining operations. Designed for continuous spindle applications, it supports a broad speed range with high stiffness and dynamic positioning. This drive integrates seamlessly with CNC controls and offers advanced monitoring capabilities. Its modular construction simplifies installation and maintenance, ensuring quick replacement in production lines.

Engineered for demanding industrial environments, the KDA 3.3-150-3-AQ0-U1 features a DC Bus Voltage of 300 V and a Rated Current of 150 A to sustain continuous power output without derating. The drive is Forced Cooled by Heatsink Blower, with an AC Supply Source for Heatsink Blower at 115 VAC, ensuring consistent thermal management under full load. A volatile-free Aux. Encoder Input supports 1 V sinusoidal signals for precise feedback, while the Speed Command Value is handled via an Analog +/- 10V interface. The unit’s Aux. Interface is omitted for applications that rely solely on spindle control, streamlining the I/O configuration and reducing complexity.

Integration into automated systems is straightforward thanks to standardized mounting and industry-proven control logic. The robust forced-air cooling and high-quality heatsink blower guarantee reliable operation in high-duty-cycle processes, minimizing thermal drift and extending component life. Ideal for CNC lathes, milling centers, and automated drilling rigs, this drive enhances spindle responsiveness and peak torque delivery, translating into higher surface finish quality and reduced cycle times.
