KDA 3.3-100-3-LPD-W1

The Bosch Rexroth Indramat KDA 3.3-100-3-LPD-W1 from the KDA Spindle Drives series is engineered for demanding spindle applications with a DC Bus Voltage of 300 V and a Rated Current of 100 A. This Product KDA features a robust Design 3 layout optimized for high stiffness and precision positioning across a wide speed range. Integration is simplified by its standardized form factor and consistent mechanical interface, while advanced control algorithms ensure smooth torque delivery under varying load conditions. With its combination of electrical robustness and compact packaging, the KDA drive excels in CNC machining centers and high-performance milling operations.

The KDA 3.3-100-3-LPD-W1 offers versatile command and feedback options to accommodate complex motion profiles. It accepts a Speed Command Value via SERCOS – Interface for high-speed digital control and includes an Aux. Interface: Position Command Value Digital 16-Bit Parallel for synchronous axis coordination. For closed-loop precision, the drive supports an Aux. Encoder Input with feedback for spindle or second motor. Auxiliary power needs are met by an AC Supply Source for Heatsink Blower of 220 VAC, ensuring reliable blower operation under continuous load.

Thermal management is handled by a Forced Cooled by Heatsink Blower system designed to maintain optimal junction temperatures during sustained operation. This cooling scheme, combined with rugged construction and high-quality components, delivers consistent performance in harsh industrial environments. Compact dimensions and a streamlined control interface make the KDA 3.3-100-3-LPD-W1 an ideal choice for machine builders seeking a high-power, precision spindle drive solution.
