The Bosch Rexroth Indramat KDA 2.1-150-3-LY0-W1 spindle drive is part of the prestigious KDA Spindle Drives series, designed to provide precise motion control in demanding industrial machining environments. Manufactured by Bosch Rexroth Indramat, this drive delivers a rated current of 150 A and operates on a DC bus voltage of 300 V, ensuring robust power delivery and consistent torque output. As a main spindle drive, it excels in applications requiring high stiffness, extensive speed ranges, and continuous power, making it an ideal choice for CNC machinery and high-speed rotary tooling.
Built on a proven product family platform, the KDA 2.1-150-3-LY0-W1 utilizes a forced cooling system via a heatsink blower to maintain optimal operating temperatures under heavy loads. The heatsink blower itself is powered by 220 VAC, enabling reliable thermal management even during continuous high-current operation. Communication and speed command input leverage a SERCOS interface, providing deterministic, real-time control signals for synchronization with modern automation systems. In addition, the drive supports auxiliary and synchronous encoder inputs, enhancing its adaptability to multi-axis feedback networks and ensuring precise positioning accuracy. Each unit is identified by a unique design number 1 and series number 2, underscoring the meticulous version control and traceability inherent in the KDA product line.
Compatibility with industry-standard SERCOS protocols ensures seamless integration into existing CNC and motion control architectures, minimizing engineering overhead and reducing commissioning time. The forced cooling method not only enhances durability under continuous high-power operation but also contributes to improved system efficiency by maintaining stable thermal conditions. As part of the KDA series, this spindle drive benefits from a modular design philosophy, simplifying maintenance and spare parts management. In industrial applications, the KDA 2.1-150-3-LY0-W1 offers exceptional reliability, high-speed responsiveness, and precise spindle control, enabling manufacturers to achieve tighter tolerances, faster cycle times, and superior overall equipment effectiveness.
