KDA 3.3-150-3-AQI-U1

KDA 3.3-150-3-AQI-U1, Bosch Rexroth Indramat, KDA Spindle Drives is a robust main spindle drive engineered for precision machining and dynamic performance. The unit delivers a continuous Rated Current of 150 A and operates on a stable DC Bus Voltage of 300 V. Its rigid architecture provides high stiffness and superior positioning accuracy across a broad speed range. Designed for demanding CNC and industrial spindle applications, it integrates advanced feedback and cooling features for reliable operation under load.

Incorporating a forced cooling scheme via a Cooling Heatsink Blower, this drive ensures efficient heat dissipation with an AC Supply Source for Heatsink Blower of 115 VAC. The Aux. Encoder Input supports a 1 V Sinusoidal Encoder signal, while the Aux. Interface offers an Incremental Encoder Output for precise position feedback. A versatile Speed Command Value accepts Analog +/- 10V inputs for smooth speed regulation. The compact Design "3" format and the dedicated Product family identifier "KDA" streamline integration into existing control architectures.

Engineers benefit from rapid commissioning and seamless integration with standard spindle control loops, enhancing reliability in high-speed milling, grinding, and turning centers. The drive's modular interface and proven mechanical stiffness deliver consistent torque and minimal vibration, extending tool life and reducing maintenance intervals. Its combination of precise feedback, robust cooling, and high-current capability makes the KDA 3.3-150-3-AQI-U1 an ideal choice for demanding industrial spindle systems.
