KDA 3.3-150-3-LYS-W1

KDA 3.3-150-3-LYS-W1, manufactured by Bosch Rexroth Indramat, is part of the high-performance KDA Spindle Drives family. This main spindle drive features high stiffness mechanics and precision positioning features, delivering continuous power across an extensive speed range for demanding machining applications. The robust design accommodates dynamic loads and rapid acceleration, ensuring consistent torque and speed regulation. Its versatile interface options support seamless integration into modern CNC systems.

Incorporating a Rated Current of 150 A and a DC Bus Voltage of 300 V, this drive balances high power density with thermal resilience. A dedicated heatsink blower draws 220 VAC from the AC supply source for efficient heat dissipation, while the Forced Cooled by Heatsink Blower scheme maintains optimum junction temperatures under sustained load. Command signals are handled via the SERCOS - Interface, delivering deterministic motion control, and a Serial Interface RS 232 C auxiliary interface simplifies parameterization and diagnostics. Enhanced feedback is provided through the With Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A) Aux. Encoder Input for accurate spindle position monitoring.

Engineers benefit from the drive’s plug-and-play compatibility with standard Indramat control architectures, reducing commissioning time and minimizing wiring complexity. The integrated cooling system and stringent component selection ensure high reliability and long service intervals in harsh workshop environments. Ideal for milling, drilling, and turning centers, the KDA 3.3-150-3-LYS-W1 spindle drive delivers precise, repeatable performance for advanced manufacturing operations.
