KDA 3.2-150-3-LQS-U1

The Bosch Rexroth Indramat KDA 3.2-150-3-LQS-U1 from the KDA Spindle Drives series is a robust main spindle drive designed for demanding machining and milling applications. Manufactured by Bosch Rexroth Indramat, this drive delivers a high Rated Current of 150 A and operates on a DC Bus Voltage of 300 V, providing a broad continuous power range and precise positioning capabilities. Its high stiffness and extensive speed range make it ideal for spindles requiring rapid acceleration and sustained torque.

This spindle drive features a dedicated AC Supply Source for Heatsink Blower rated at 115 VAC, ensuring efficient thermal management through its Forced Cooled by Heatsink Blower system. The inclusion of an Aux. Encoder Input for 1 V sinusoidal encoders enhances feedback accuracy, while the Aux. Interface employs a Serial Interface RS 232 C for reliable communication and configuration. Speed commands are transmitted via the SERCOS - Interface, offering deterministic data exchange and real-time control. With a compact design (Design 2) and the proven KDA product architecture, this module supports series 3 spindles with minimal footprint and high integration flexibility.

The KDA 3.2-150-3-LQS-U1 drive is engineered for long-term reliability and efficient operation. Its forced-air cooling and precision encoder support ensure consistent performance under heavy loads and temperature fluctuations. The serial control interface and standardized SERCOS protocol facilitate seamless integration into modern CNC systems, while the robust Heatsink Blower supply minimizes downtime due to thermal overload. Compliant with industry best practices for spindle drives, this module offers reduced maintenance cycles and enhanced energy efficiency. In industrial applications, it delivers high dynamic response, optimal torque control, and superior process reliability for milling, turning, and grinding operations.
