KDA 3.2-150-3-DQI-U1

The Bosch Rexroth Indramat KDA 3.2-150-3-DQI-U1 Main Spindle Drive is a high-performance module in the KDA Spindle Drives series engineered by Bosch Rexroth Indramat. It delivers a rated current of 150 A and operates on a DC bus voltage of 300 V. Characterized by high stiffness, precise positioning capabilities and an extensive continuous speed range, this drive is optimized for spindle applications in CNC machining, milling and turning centers.

This drive unit incorporates a forced cooling system via a dedicated heatsink blower powered by an AC supply source of 115 VAC, ensuring reliable thermal management under sustained loads. Speed is commanded through a Digital 16-Bit Parallel Speed Command Value interface, providing high resolution and fast response. Feedback integration is achieved via an Aux. Encoder Input for 1 V sinusoidal encoders and an Incremental Encoder Output auxiliary interface, enabling seamless synchronization with motion controllers and real-time position monitoring.

Designed in a compact Design 2 housing, the KDA 3.2-150-3-DQI-U1 offers robust construction to withstand industrial environments. Its compatibility with standard spindle encoder formats and its efficient forced-cooling arrangement enhance long-term reliability and uptime. The modular nature of the drive simplifies installation and maintenance, while its digital control architecture maximizes precision and energy efficiency. By combining high current capacity, precise speed regulation and advanced encoder support, this spindle drive delivers tangible benefits in productivity, accuracy and durability for demanding industrial machining applications.
