KDA 2.1-100-3-A00-W1-220

The Bosch Rexroth Indramat KDA 2.1-100-3-A00-W1-220 from the KDA Spindle Drives line combines precision engineering with robust performance, featuring a Rated Current: 100 A and a DC Bus Voltage: 300 V for stable, high-torque spindle applications. This drive accepts an AC Supply Source for Heatsink Blower: 220 VAC and delivers control via a Speed Command Value: Analog +/- 10V interface, ensuring seamless integration with analog control systems. With Cooling: Forced Cooled by Heatsink Blower, the unit maintains optimal thermal conditions under continuous operation. Designed and built by Bosch Rexroth Indramat, this drive meets demanding requirements for stiffness and responsiveness in modern machining centers.

Engineered as part of the broader KDA architecture, this Main Spindle Drive carries a Product: KDA designation and is identified by Design: 1 within the family. Its Series: 2 configuration underscores incremental improvements in control precision and power density over earlier releases. The absence of auxiliary modules—both Aux. Encoder Input: Without and Aux. Interface: Without—streamlines the control flow and reduces potential points of failure in spindle feedback loops. Enhanced positioning features and a broad speed range with continuous power output equip the drive to handle a variety of spindle speeds with rapid acceleration and deceleration cycles.

Installation is simplified by the drive’s compact footprint and the self-contained Forced Cooled by Heatsink Blower system, which eliminates the need for external coolant circuits and lowers maintenance overhead. Thermal stability is further reinforced by high-efficiency heat transfer from the heatsink blower assembly, ensuring reliable operation even under peak loading conditions. Altogether, the KDA 2.1-100-3-A00-W1-220 spindle drive delivers a balanced combination of power, control accuracy, and ruggedness for CNC spindles in demanding production environments.
