The Bosch Rexroth Indramat KDA 3.3-050-3-DQ0-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat combines high-torque precision with robust industrial design. Engineered as a Design 3 unit within the Product KDA family, this spindle drive offers a Rated Current of 50 A and a DC Bus Voltage of 300 V for continuous, high-performance operation. Its native Speed Command Value is a Digital 16-Bit Parallel interface, ensuring precise velocity control across a wide operational range. Incorporating advanced positioning functions and dynamic stiffness, the drive excels in demanding CNC and machining applications.
Cooling and thermal management are optimized through a Forced Cooled by Heatsink Blower system, driven by an AC Supply Source for Heatsink Blower at 115 VAC. The drive supports an Aux. Encoder Input for 1V Sinusoidal Encoder feedback, facilitating smooth commutation and enhanced positioning accuracy. While it features an Aux. Interface configured as Without auxiliary communications, the streamlined design minimizes potential points of failure. The overall architecture balances compactness with ruggedness, maintaining consistent performance even under high-duty cycles.
Built on the proven KDA platform, this spindle drive delivers reliable, repeatable operation in precision machining centers, turning lathes, and milling equipment. Its forced-air cooling and precise encoder integration reduce thermal drift and maintain torque stability at high speeds. Certified to meet industrial durability standards, the KDA 3.3-050-3-DQ0-U1 ensures simplified integration and long-term uptime, making it an ideal solution for high-precision spindle control tasks.
