KDA 3.1-100-3-A00-W1

The KDA 3.1-100-3-A00-W1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive excels in high-speed machining applications by combining robust construction with precise control. Its compact housing and streamlined power stage deliver consistent performance across extended operational cycles. Advanced positioning algorithms and stiff mechanical coupling enable rapid acceleration and deceleration, reducing cycle times in demanding manufacturing environments. The drive’s integration into existing CNC frameworks is seamless, supporting both legacy and modern control protocols.

Engineered for reliability, this spindle drive features a DC Bus Voltage of 300 V and a continuous Rated Current of 100 A to sustain high torque loads. Thermal management is handled via a Cooling system that is Forced Cooled by Heatsink Blower, with an AC Supply Source for Heatsink Blower rated at 220 VAC. Command inputs are accommodated through a Speed Command Value interface of Analog +/- 10V, while streamlined connectivity is maintained by an Aux. Encoder Input option of Without and an Aux. Interface of Without. The drive’s structural integrity is defined by a Design classification of 1, ensuring consistent performance under variable load conditions.

Installation is simplified by the KDA series’ modular mounting system, allowing fast integration into machining centers and retrofit projects. Built-in fault diagnostics and protective interlocks enhance uptime and safeguard spindle motors against overload or thermal stress. With proven resistance to electrical and mechanical disturbances, the KDA 3.1-100-3-A00-W1 offers lasting reliability for CNC spindles, milling heads, and high-precision drilling operations.
