KDA 3.3-100-3-DQI-W1

The KDA 3.3-100-3-DQI-W1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive delivers industry-leading rigidity and precision. Its robust design supports advanced positioning features and an extensive speed range, providing continuous power for demanding machining tasks. Built to excel under heavy loads, it integrates seamlessly with CNC control systems and maintains performance over long production runs. Optimized for spindle applications, it combines dynamic response with reliable torque delivery.

This drive features a DC Bus Voltage of 300 V and a Rated Current of 100 A, ensuring ample power headroom. Cooling is handled by a forced cooled by heatsink blower scheme powered from a AC Supply Source for Heatsink Blower of 220 VAC, preserving performance in high-duty cycles. Motion feedback is supported through an Aux. Encoder Input for 1 V sinusoidal encoders and an Aux. Interface offering an incremental encoder output. Speed is commanded via a Digital 16-Bit Parallel interface for precise velocity control. The drive’s Design 3 construction and rugged heatsink blower module combine to maximize thermal stability and minimize downtime.

Engineers benefit from the KDA’s plug-and-play integration with standard spindle control architectures and its proven reliability in continuous operation. The precision speed command interface and powerful DC bus enable rapid acceleration and consistent torque, reducing cycle times. Ideal for high-speed milling, drilling, and planetary grinding applications, the KDA 3.3-100-3-DQI-W1 ensures uptime and accuracy in the most challenging machining environments.
