KDA 3.1-150-3-API-W1

The Bosch Rexroth Indramat KDA 3.1-150-3-API-W1 from Bosch Rexroth Indramat is a high-performance member of the KDA Spindle Drives series. It delivers precise spindle control with high stiffness and an extensive speed range, making it well suited for demanding machining operations. Continuous power handling and advanced positioning features ensure fast dynamic response and repeatable accuracy. Its modular design allows straightforward field upgrades and simplifies maintenance in automated production environments.

Branded as Product KDA and classified under Series 3, this drive features a Rated Current of 150 A and a DC Bus Voltage of 300 V, sustaining stable torque across the entire speed band. Speed is commanded via an Analog +/- 10V Speed Command Value, while thermal management relies on Forced Cooled by Heatsink Blower cooling powered by an AC Supply Source for Heatsink Blower of 220 VAC. Feedback loops are supported through an Aux. Encoder Input for spindle or secondary motor feedback, complemented by an Aux. Interface providing an Incremental Encoder Output channel. Packaged as a compact Design level 1 module, it integrates seamlessly into standard drive racks and control cabinets.

Engineers benefit from plug-and-play encoder connectivity and front-access cooling components, significantly reducing commissioning time and maintenance effort. The forced-cooling architecture and robust component selection deliver high reliability under continuous operation. Ideal for milling, drilling, and grinding spindles in high-precision machine tools, it ensures stable torque delivery and repeatable precision in complex manufacturing processes.
