KDA 3.3-150-3-A00-V

KDA 3.3-150-3-A00-V, manufactured by Bosch Rexroth Indramat, is part of the KDA Spindle Drives series and represents a robust solution for demanding spindle applications. This main spindle drive delivers precision motion control with high stiffness and an extensive speed range, making it ideal for machining centers and industrial CNC spindles. Its advanced control algorithms ensure stable positioning and repeatable performance under varying loads. The compact, modular architecture supports straightforward integration into existing automation systems.

Incorporating a Rated Current of 150 A and a DC Bus Voltage of 300 V, the KDA drive sustains continuous torque over long production runs. A Forced Cooled by Heatsink Blower configuration maintains optimal thermal management, with an AC Supply Source for Heatsink Blower set to Factory Assigned parameters to match plant power environments. Speed is governed via an Analog ±10V Speed Command Value interface, while the drive’s structural Design is a rugged 3 under the Bosch Rexroth product taxonomy. For streamlined installations, both the Aux. Encoder Input and the Aux. Interface are specified as Without, reducing wiring complexity and potential failure points.

Engineers will appreciate the KDA drive’s seamless compatibility with Rexroth control platforms and its high mean time between failures (MTBF) for increased uptime. The robust enclosure and precision components ensure reliability even in harsh workshop conditions, while the drive’s modular footprint simplifies maintenance and spare-part replacement. Ideal for high-speed spindles, milling machines, and turning centers, the KDA 3.3-150-3-A00-V delivers consistent torque, precise speed regulation, and long-term operational stability.
