KDA 3.1-150-3-DYI-U1

The Bosch Rexroth Indramat KDA 3.1-150-3-DYI-U1 is a high-performance spindle drive in the renowned KDA Spindle Drives series, designed specifically for precision control of high-speed automated spindles. This drive features a peak force of 3.1 kN and a continuous force of 1.9 kN, delivering robust power for demanding machining applications. With a stroke length of 150 mm and an ironless linear motor design, it excels in delivering rapid, accurate linear motion. Its primary function is to convert control signals into precise motor output, ensuring stable spindle speed and torque under varying load conditions.

Incorporating advanced technical specifications, the KDA 3.1-150-3-DYI-U1 operates on a DC Bus Voltage of 300 V and sustains a rated current of 150 A, providing ample energy for continuous high-load operation. Velocity control is executed with a maximum speed of 3 m/s, while position feedback is ensured by a high-resolution linear encoder interface. A 16-bit parallel speed command interface receives precise reference signals from the motion controller, enabling minimal latency in speed adjustments. To manage thermal stress, this drive employs forced cooling via a heatsink blower, which directs airflow across power electronics to maintain optimal temperatures. An auxiliary encoder input with synchronous inputs further enhances integration flexibility, supporting incremental encoding for real-time monitoring.

Built for industrial environments, the KDA 3.1-150-3-DYI-U1 offers seamless compatibility with external motion controllers and monitoring systems through its auxiliary interface. The ironless linear motor architecture reduces wear and improves overall durability, while the efficient cooling system minimizes downtime due to overheating. With its robust 150 A current capacity and 300 V bus voltage, this drive ensures high operational efficiency and consistent performance. Ideal for industrial automation and machining centers, it delivers precise motion control, reliable feedback, and long-term operational stability, ultimately improving productivity and surface finish quality in demanding production settings.
