The Bosch Rexroth Indramat KDA 3.1-050-3-DQS-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision spindle control with robust power throughput. Designed for demanding machining centers, it features a Rated Current of 50 A and a DC Bus Voltage of 300 V to ensure continuous torque delivery across a broad speed range. Compact yet sturdy, the KDA 3.1-050-3-DQS-U1 supports high stiffness and positioning accuracy for milling, drilling, and grinding applications. Its proven reliability in industrial environments makes it a go-to choice for manufacturers seeking repeatable spindle performance.
This spindle drive integrates a Digital 16-Bit Parallel Speed Command Value interface for exact velocity control and a Serial Interface RS 232 C Aux. Interface for streamlined system integration. The unit incorporates an Aux. Encoder Input for 1V Sinusoidal Enc. to synchronize feedback signals with minimal latency. Forced cooling is managed through a dedicated heatsink blower rated at 115 VAC AC Supply Source for reliable thermal regulation. The design (Design 1) and product designation (Product KDA) follow standardized footprints within the Series 3 platform, simplifying panel layouts and retrofits.
Engineered for continuous, high-duty cycle operation, the KDA 3.1-050-3-DQS-U1 combines force-cooled durability with digital control finesse. Its precision encoders and stable DC bus architecture translate into minimal drift and superior surface finishes on finished parts. With industry-proven components and Bosch Rexroth Indramat quality assurance, this spindle drive stands ready to elevate machine tool productivity and uptime.
