KDA 3.3-100-3-DYI-W1

The Bosch Rexroth Indramat KDA 3.3-100-3-DYI-W1 is a high-performance spindle drive from the KDA Spindle Drives series, designed to deliver precise motion control in demanding industrial applications. As a main spindle drive, it supports a Rated Current of 100 A and a DC Bus Voltage of 300 V, ensuring robust power delivery for continuous operation. This drive’s primary function is to regulate spindle speed and torque with high stiffness, making it ideal for CNC machining centers and other high-precision tooling systems.

Incorporating advanced control features, the KDA 3.3-100-3-DYI-W1 is forced cooled by a heatsink blower operating on a 220 VAC AC supply source, ensuring reliable thermal management under sustained loads. Its Digital 16-Bit Parallel Speed Command Value interface provides high-resolution speed setpoints for exact positioning and smooth acceleration. The drive includes an Aux. Encoder Input with auxiliary and synchronous inputs (AS 35 interface) for real-time feedback, and an Aux. Interface offering incremental encoder output to seamlessly integrate with external control systems. The robust design (Design 3) and product classification (Product KDA, Series 3) underscore its engineered reliability.

Beyond its core performance metrics, the KDA drive excels in compatibility and efficiency. Its forced-cooling system not only enhances heat dissipation but also prolongs component life, reducing maintenance intervals. The inclusion of both synchronous and incremental encoder interfaces ensures interoperability with a wide range of machine tools and automation platforms. With its digital speed command architecture and hardened industrial design, this spindle drive meets the stringent demands of modern production environments. Employing this drive in industrial setups results in improved machining accuracy, consistent cycle times, and elevated overall equipment effectiveness (OEE).
