The Bosch Rexroth Indramat KDA 3.3-050-3-DPS-W1 drive is a premium solution from the KDA Spindle Drives series, engineered for high-precision spindle applications. With a Rated Current of 50 A and a DC bus voltage of 300 V, this main spindle drive delivers continuous power across a wide speed range. Designed to provide exceptional stiffness and positioning accuracy, it excels in demanding CNC milling, turning, and grinding operations where reliable torque and speed control are essential.
This drive integrates multiple technical innovations to ensure superior performance. The heatsink blower system operates on an AC Supply Source for Heatsink Blower of 220 VAC, providing forced cooling for stable thermal management during extended duty cycles. For feedback and monitoring, the drive offers an Aux. Encoder Input for spindle or second motor feedback, ensuring precise speed and position tracking. Communication and parameterization are facilitated via the Aux. Interface: Serial Interface RS 232 C, supporting rapid commissioning and diagnostics. Cooling is achieved through forced convection by the heatsink blower, maintaining optimal operating temperatures and protecting internal components.
Built on a robust Design 3 chassis and classified under Series 3, this KDA drive ensures compatibility with standard spindle motor interfaces and industrial control systems. The Speed Command Value is supplied as a digital 16-bit parallel signal, enabling high-resolution speed setpoint fidelity and seamless integration with PLCs and motion controllers. Its forced cooling mechanism enhances efficiency and prolongs service life, minimizing downtime in harsh industrial environments. Ideal for machine tool builders and retrofit applications, the KDA 3.3-050-3-DPS-W1 delivers reliable performance, precise control, and long-term durability in high-speed spindle drive applications.
