KDA 3.1-150-3-AQI-W1

The Bosch Rexroth Indramat KDA 3.1-150-3-AQI-W1 from the Bosch Rexroth Indramat KDA Spindle Drives series provides robust spindle control with high stiffness and precision positioning. This main spindle drive delivers a continuous Rated Current of 150 A at a DC Bus Voltage of 300 V, ensuring reliable power delivery across an extensive speed range. Its streamlined footprint and modular architecture simplify installation in new or retrofit machine tool applications. An analog +/-10V speed command interface allows for intuitive integration with existing control systems.

Incorporating a forced-cooling scheme, the drive is Forced Cooled by Heatsink Blower and requires only a standard AC Supply Source for Heatsink Blower of 220 VAC for optimal thermal management. The unit features an Aux. Encoder Input for 1V Sinusoidal Enc. feedback and an Aux. Interface providing an Incremental Encoder Output for high-resolution position monitoring. Classified under Design code 1 and identified as Product model KDA, it belongs to Series 3 of the KDA family. Rapid analog control is achieved through the Speed Command Value channel, offering precise velocity setpoint adjustments.

Engineered for seamless incorporation into CNC spindles and machining centers, the KDA 3.1-150-3-AQI-W1 drive ensures stable torque delivery during high-speed operations. Its forced-air heatsink blower increases service intervals and reduces maintenance interruptions, while encoder feedback loops maintain positional accuracy under varying loads. The result is a highly reliable drive solution, ideal for precision milling, drilling, and grinding applications.
