KDA 3.3-050-3-DQS-W1

The Bosch Rexroth Indramat KDA 3.3-050-3-DQS-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision spindle control with a rated current of 50 A and a robust DC Bus Voltage of 300 V. Built on a Design 3 platform and part of the Product KDA family, this drive supports demanding machining tasks while maintaining high stiffness and exceptional dynamic response. Integration is simplified via a dedicated Aux. Encoder Input for 1V Sinusoidal Enc. and a configurable Aux. Interface Serial Interface RS 232 C. The drive’s AC Supply Source for Heatsink Blower 220 VAC supply ensures stable auxiliary power for continuous operation.

Featuring a forced cooling system, the KDA 3.3-050-3-DQS-W1 is Cooling Forced Cooled by Heatsink Blower to sustain optimal thermal management under heavy load and extended runtime. Its Speed Command Value Digital 16-Bit Parallel input guarantees high-resolution velocity control across a wide speed range, enabling seamless transitions between low-speed positioning and high-speed operations. The spindle drive’s design emphasizes rigidity and positional repeatability, making it ideal for milling, grinding, and drilling applications where surface finish and dimensional accuracy are critical.

Compact yet powerful, the KDA Main Spindle Drive combines advanced digital control with rugged hardware construction for reliable production duty. Its modular architecture and standardized interfaces simplify installation and maintenance, reducing downtime and accelerating system commissioning. Whether deployed in gantry mills, high-speed machining centers, or precision lathes, the KDA 3.3-050-3-DQS-W1 sets the benchmark for spindle drive performance in modern manufacturing environments.
