KDA 3.3-100-3-DQ0-W1

The Bosch Rexroth Indramat KDA 3.3-100-3-DQ0-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision spindle control with unmatched rigidity and dynamic response. This main spindle drive features a Rated Current of 100 A and a DC Bus Voltage of 300 V, ensuring continuous power delivery across extensive speed ranges. The unit employs a Digital 16-Bit Parallel Speed Command Value for high-resolution interpolation, while its Design 3 configuration and robust Product KDA architecture optimize mechanical stiffness. Compact yet powerful, the drive supports a Series 3 footprint that eases integration into existing machine tool cabinets.

Reliability and thermal management are built into every component: forced cooling is provided via a Heatsink Blower operating on a dedicated AC Supply Source for Heatsink Blower 220 VAC, maintaining stable junction temperatures under peak load. The module accepts precise feedback through an Aux. Encoder Input for 1V Sinusoidal Enc., yet omits auxiliary communication ports with an Aux. Interface Without expansion slot to minimize noise paths. The robust heatsink blower system and absence of auxiliary interface points reduce maintenance points and enhance uptime in demanding CNC environments.

Engineered for metalcutting accuracy and repeatable positioning, the drive’s high-speed spindle control capitalizes on its advanced cooling and encoder features to deliver smooth torque delivery. Its sealed construction combined with optimized airflow ensures dependable performance in harsh industrial conditions. Ideal for high-speed milling, drilling, and precision grinding spindles, the KDA 3.3-100-3-DQ0-W1 sets a new benchmark for spindle drive solutions in modern manufacturing.
