KDA 3.3-100-3-LPI-U1

The Bosch Rexroth Indramat KDA 3.3-100-3-LPI-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers robust performance with a Rated Current of 100 A and a DC Bus Voltage of 300 V. This Product KDA in Design 3 integrates a precision Speed Command Value: SERCOS Interface to ensure accurate spindle control across a broad speed range. Its high stiffness and positioning capabilities are tailored for main spindle applications where continuous power and dynamic response are critical. Built on proven KDA architecture, this drive supports demanding machining and milling operations.

Reliability is enhanced through a dedicated Cooling: Forced Cooled by Heatsink Blower system driven by an AC Supply Source for Heatsink Blower of 115 VAC. Dual feedback paths include an Aux. Encoder Input with support for spindle or second motor feedback alongside an Aux. Interface: Incremental Encoder Output to maintain tight loop control. The modular design allows easy integration into existing SERCOS networks, and the blower-forced heatsink ensures stable thermal performance under peak loads.

Engineered for industrial spindle applications, this KDA drive combines structural rigidity with advanced servo features in a compact footprint. The combination of high current capacity and reliable encoder interfaces makes the KDA 3.3-100-3-LPI-U1 an ideal choice for CNC machining centers, grinding spindles, and high-precision tooling systems. Its flexible configuration and robust design minimize downtime and streamline commissioning in high-speed metalworking environments.
