KDA 3.3-100-3-LQI-W1

The Bosch Rexroth Indramat KDA 3.3-100-3-LQI-W1 spindle drive from the Bosch Rexroth Indramat KDA Spindle Drives series delivers robust performance for high-precision machining applications. Engineered for main spindle control, it offers exceptional stiffness and dynamic response across a broad speed range. Its compact design supports seamless integration into milling and turning centers. With a focus on continuous power delivery and precise positioning, this drive excels in demanding production environments.

At its core, the drive features a 300 V DC Bus Voltage and sustains a continuous 100 A Rated Current for consistent torque output under load. Cooling is achieved through a Forced Cooled by Heatsink Blower scheme, powered via a dedicated 220 VAC AC Supply Source for Heatsink Blower to maintain thermal stability during extended cycles. Motion feedback is handled by a With Aux. Encoder Input for 1V Sinusoidal Enc. enabling high-resolution position monitoring, while the Incremental Encoder Output Aux. Interface facilitates real-time data exchange with the CNC controller. The module’s SERCOS - Interface Speed Command Value interface provides deterministic communication, ensuring microsecond-level synchronization in multi-axis systems. Built on a sturdy Design 3 Product KDA platform with an optimized thermal path, it achieves high power density without compromise.

Engineers benefit from plug-and-play compatibility with standard SERCOS networks, reducing commissioning time and simplifying diagnostics through integrated status monitoring. Its forced-air heatsink blower and robust electronic topology enhance operational reliability even under constant heavy loads. Ideal for high-speed spindles in precision milling, turning, or grinding centers, the KDA 3.3-100-3-LQI-W1 combines precise motion control with durability for optimal uptime and performance.
