KDA 3.3-100-3-DY0-U1

The Bosch Rexroth Indramat KDA 3.3-100-3-DY0-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers robust performance as a main spindle drive with a Rated Current of 100 A and a DC Bus Voltage of 300 V. Designed in a compact 3 design format within the KDA product family, this drive features a Digital 16-Bit Parallel Speed Command Value for precise motion control. The drive’s cooling system is Forced Cooled by Heatsink Blower, operating from an AC Supply Source for Heatsink Blower: 115 VAC to maintain stable thermal conditions. With auxiliary encoder support via With Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A), it offers versatile integration into high-performance machining centers.

Performance and reliability are enhanced by the drive’s Aux. Interface: Without design that eliminates unnecessary I/O complexity, while the forced cooling blower ensures consistent heat dissipation under continuous load. The main spindle drive accepts synchronization signals through the built-in auxiliary encoder input, optimizing stiffness and positioning accuracy across a wide speed range. Engineers benefit from a modular architecture that simplifies maintenance and reduces downtime, thanks to the standardized series 3 form factor.

Ideal for demanding industrial applications, the KDA 3.3-100-3-DY0-U1 excels in CNC milling, grinding, and high-speed drilling operations where torque density and thermal stability are critical. Its combination of 300 V DC bus voltage, 100 A current handling, and digital command interface makes it a premiere choice for precision machining and high-stiffness spindle control.
