KDA 3.3-050-3-D0S-W1

The KDA 3.3-050-3-D0S-W1, Bosch Rexroth Indramat, KDA Spindle Drives product is engineered for demanding spindle applications that require high rigidity and precision. It features advanced positioning capabilities and an extensive speed range with continuous power delivery, making it ideal for main spindle tasks. With a robust design and proven performance, this drive supports stable operation under dynamic loads. The integrated control interface simplifies setup and diagnostics on machine tools.

Designed as a Design level 3 drive in the Product KDA line, it draws a DC Bus Voltage of 300 V and delivers a Rated Current of 50 A for sustained torque output. Cooling is achieved via a Cooling system of Forced Cooled by Heatsink Blower powered by a dedicated AC Supply Source for Heatsink Blower at 220 VAC, ensuring thermal stability under heavy duty. The drive accepts a Speed Command Value in Digital 16-Bit Parallel format and provides an Aux. Interface via Serial Interface RS 232 C, while the Aux. Encoder Input is specified as Without to streamline signal paths. A modular construction and compact footprint facilitate installation in tight machine tool cabinets.

Engineers benefit from the drive’s plug-and-play integration with CNC controls and its high reliability across extended production cycles. Built on Bosch Rexroth Indramat’s proven KDA architecture, the KDA 3.3-050-3-D0S-W1 ensures minimal downtime and consistent spindle performance. Its combination of precision, power density, and straightforward interface makes it an excellent choice for metalworking, milling, and turning centers.
