KDA 3.2-100-3-LP0-W1

The Bosch Rexroth Indramat KDA 3.2-100-3-LP0-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat combines high stiffness with precision positioning features and an extensive speed range under continuous power, making it a standout main spindle drive. With a rated current of 100 A and a DC bus voltage of 300 V, this unit ensures robust torque delivery across a broad RPM band. Designated as Product KDA, Design 2, it leverages a modular architecture for seamless integration into advanced CNC and automation platforms. The built-in SERCOS-interface speed command value supports deterministic communication for synchronized multiaxis machining.

Thermal stability is maintained through a forced-cooled heatsink blower powered by a dedicated 220 VAC AC supply source for heatsink blower, ensuring reliable heat dissipation during high-duty cycles. Feedback versatility is provided by an auxiliary encoder input with spindle or second motor feedback, while the streamlined configuration omits an auxiliary interface to reduce component count and simplify wiring. Core mechanical and electrical staging is defined by Series 3, offering a compact footprint without compromising dynamic torque response. These specifications collectively yield rapid acceleration, consistent speed control, and minimal torque ripple in demanding cutting operations.

The KDA 3.2-100-3-LP0-W1’s advanced thermal management and versatile feedback options make it ideally suited for high-precision CNC spindle applications. Its preconfigured, integration-ready format and precise current control shorten commissioning times and mitigate downtime during maintenance. Engineered for continuous operation in 24/7 production environments, it delivers long-term reliability and repeatable performance in the most challenging machining processes.
