KDA 3.3-100-2-A00-W1

The Bosch Rexroth Indramat KDA 3.3-100-2-A00-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision spindle control with robust current handling and versatile voltage compatibility. This spindle drive supports a rated voltage of 300 V DC bus, combined with a current rated of 100 A for peak demands and a continuous current of 70 A to maintain stable operation under varying loads. Integrated within the drive is a heatsink blower powered by a rated connection voltage for attached blower of AC 50–60 Hz, providing forced cooling that preserves performance at high duty cycles. With its analog +/-10 V speed command input and no auxiliary encoder option, the KDA 3.3-100-2-A00-W1 ensures straightforward setup and reliable feedback in machining and high-speed applications.

Featuring a hardened design for high stiffness and an extensive speed range, this controller excels in applications requiring precise positioning and rapid acceleration. The series 3, design 3 architecture reflects legacy compatibility while offering modern thermal management via the built-in blower that prevents overheating during continuous operation. The lack of an auxiliary interface simplifies the electrical footprint and reduces potential failure points, while its compact form factor ensures seamless integration into machine tool control panels. Maintenance demands remain low thanks to the blower’s efficient forced-air circulation and the drive’s rugged construction.

Engineered for reliability, the KDA 3.3-100-2-A00-W1 provides continuous power delivery across demanding spindle workloads, minimizing downtime and maintenance costs. Its combination of 300 V DC bus voltage, configurable 100 A peak current, and precision analog command input makes it an ideal solution for CNC machining centers, high-speed drilling, and milling operations. Trust Bosch Rexroth Indramat’s renowned quality to deliver consistent, high-performance spindle control in even the most challenging industrial environments.
