KDA 3.1-150-3-LYI-W1

The KDA 3.1-150-3-LYI-W1, produced by Bosch Rexroth Indramat as part of the KDA Spindle Drives line, delivers robust performance for high-precision spindle control. This main spindle drive boasts a Product Family designation of KDA and a Series index of 3, ensuring compatibility with existing Indramat infrastructures. Its compact Design: 1 enclosure integrates seamlessly into machine tool environments while supporting a wide continuous power range and stiff positioning capabilities. With an industry-focused architecture, it addresses demanding stiffness and dynamic response requirements in modern machining centers.

The drive accepts a DC Bus Voltage of 300 V and supplies a continuous Rated Current of 150 A, enabling sustained torque output under heavy loads. Forced cooling is provided by a Cooling Method of Forced air via heatsink blower, powered by a dedicated Heatsink Blower AC Supply of 220 VAC to maintain optimal thermal conditions. On the control side, the Speed Command Interface utilizes SERCOS, delivering deterministic digital motion commands and precise synchronization with peripheral axes. Dual-mode feedback is supported through an Auxiliary Encoder Input Type of Auxiliary & Synchronous and an Auxiliary Interface Type of Incremental Encoder Output, allowing high-resolution position feedback and closed-loop stability. The drive’s integrated bus capacitors and rugged power transistors ensure minimal voltage ripple and high overload tolerance.

Engineers benefit from the KDA 3.1-150-3-LYI-W1’s plug-and-play integration with standard Indramat controllers and servo motors, reducing installation time and simplifying system architecture. The rugged construction and forced-air heatsink blower guarantee reliable operation in harsh shop-floor conditions, minimizing downtime. Ideal for milling, turning, and grinding applications, this spindle drive delivers precise speed regulation, high stiffness, and long-term reliability for demanding manufacturing processes.
