KDA 3.1-050-3-D0D-W1

KDA 3.1-050-3-D0D-W1, Bosch Rexroth Indramat, KDA Spindle Drives represents a high-performance main spindle drive engineered for precision machining. The unit delivers a Rated Current of 50 A and a robust DC Bus Voltage of 300 V to maintain continuous power in demanding applications. A forced-air cooling method via an integrated heatsink blower ensures consistent thermal management under full load. Its compact design supports stiff, accurate positioning and wide speed range without compromising dynamic response.

The drive incorporates a Cooling system specified as Forced Cooled by Heatsink Blower powered by a dedicated AC Supply Source for Heatsink Blower of 220 VAC for reliable heat dissipation. A Speed Command Value input is provided as Digital 16-Bit Parallel through an Aux. Interface labeled Position Command Value Digital 16-Bit Parallel, enabling high-resolution velocity control. The unit’s Design is classified as 1 with a rugged Product designation KDA, part of Series 3. Note that the Aux. Encoder Input is specified as Without encoder feedback, simplifying integration in encoderless setups.

Engineers benefit from the drive’s seamless integration into Bosch Rexroth Indramat control platforms, leveraging existing DC bus networks for regenerative energy efficiency. Built with industrial-grade components and a proven cooling strategy, the KDA 3.1-050-3-D0D-W1 ensures operational reliability in harsh environments. Its combination of high stiffness, precision speed control, and straightforward installation makes it ideal for spindle applications in milling, turning, and grinding machinery.
