KDA 3.1-150-3-DPD-W1

The Bosch Rexroth Indramat KDA 3.1-150-3-DPD-W1 drive is a high-performance component within the KDA Spindle Drives series, engineered by Bosch Rexroth Indramat for advanced motion control applications. As a Main Spindle Drive, it delivers exceptional stiffness and precision positioning features, enabling smooth and accurate spindle operation. Key specifications include a Rated Current of 150 A to sustain demanding torque requirements and a DC Bus Voltage of 300 V for efficient power distribution. Its design supports an extensive speed range with continuous power output, making it ideal for machine tool spindles and high-speed rotational processes.

Engineered for robustness and precision, the KDA 3.1-150-3-DPD-W1 integrates a DC Bus Voltage of 300 V to supply consistent energy to the spindle motor. Thermal management is achieved through a forced cooled by heatsink blower system, powered by an AC supply source for heatsink blower of 220 VAC, ensuring effective heat dissipation during prolonged operation. Control signals are managed via a Position Command Value Digital 16-Bit Parallel interface, which delivers high-resolution speed commands for rapid response and fine motion control. The drive also features an Aux. Encoder Input for spindle or second motor feedback, enhancing closed-loop accuracy and enabling synchronization in multi-axis configurations.

Beyond its core functionality, the KDA 3.1-150-3-DPD-W1 offers seamless compatibility with a variety of spindle encoders and auxiliary interfaces, facilitating integration into complex automation systems. Its forced-cooling mechanism ensures consistent performance under continuous heavy loads and extends component service life. The digital control architecture minimizes latency and maximizes efficiency, reducing cycle times and energy consumption. Designed to meet rigorous industrial standards, this spindle drive delivers reliable operation, low maintenance requirements, and superior dynamic response—benefits that translate into increased productivity and precision in modern manufacturing environments.
