KDA 3.1-050-3-API-U1

The Bosch Rexroth Indramat KDA 3.1-050-3-API-U1 drive is part of the renowned KDA Spindle Drives series, designed as a high-performance main spindle drive for precision machining applications. Manufactured by Bosch Rexroth Indramat, this unit delivers a Rated Current of 50 A and operates on a DC Bus Voltage of 300 V, ensuring ample continuous power for demanding spindle operations. Its high stiffness and broad speed range make it ideal for applications requiring accurate positioning and consistent rotational performance.

Featuring forced cooling via a dedicated heatsink blower, the KDA 3.1-050-3-API-U1 maintains optimal thermal management under heavy loads. The drive accepts an analog +/- 10 V Speed Command Value for smooth and precise speed regulation. It interfaces with auxiliary feedback devices through an Aux. Encoder Input for spindle or second motor feedback and provides an Aux. Interface with incremental encoder output to facilitate seamless integration with modern CNC controllers. The AC supply for the heatsink blower is rated at 115 VAC, supporting reliable forced-cooled operation and preventing thermal overload during extended cycles.

The robust design of the KDA 3.1-050-3-API-U1 ensures compatibility with a wide range of spindle motors and control systems, thanks to its standardized encoder interfaces and analog command options. Forced cooling by the heatsink blower enhances efficiency and prolongs component life by maintaining consistent operating temperatures. As a component of the KDA Series, it adheres to Bosch Rexroth’s rigorous quality standards and offers durable performance in industrial environments. Incorporating this spindle drive into machining systems improves productivity, stability, and precision, delivering significant benefits for high-speed and high-accuracy manufacturing processes.
