KDA 3.1-150-3-DQD-W1, Bosch Rexroth Indramat, KDA Spindle Drives opens a new benchmark in high-performance spindle control with its robust architecture and precision-focused design. This main spindle drive delivers a continuous Rated Current of 150 A and maintains a DC Bus Voltage of 300 V for seamless power conversion. The unit’s high stiffness and wide speed range ensure unparalleled positioning accuracy and dynamic response. Integrated forced cooling via a dedicated heatsink blower preserves thermal stability under peak loads.
Designed for advanced CNC and machining applications, the drive features an AC Supply Source for Heatsink Blower of 220 VAC to power its active cooling module, eliminating the need for external fans. An Aux. Encoder Input accepts a 1 V sinusoidal encoder signal for closed-loop position feedback, while the Aux. Interface provides a Position Command Value Digital 16-Bit Parallel link for deterministic control. The Speed Command Value is likewise delivered as Digital 16-Bit Parallel, guaranteeing cycle-accurate velocity setpoints. With a modular Design identifier of 1, the product classification is marked as Product "KDA" and falls under Series "3" for streamlined component matching and spare parts management.
Deployment of the KDA 3.1-150-3-DQD-W1 spindle drive enhances system reliability through its forced air cooling architecture and rugged power stage, accommodating continuous operation in harsh environments. Its precise 16-bit command interfaces simplify integration into multi-axis CNC platforms, while the high current capacity and stable DC bus ensure consistent torque delivery. Ideal for high-rigidity milling, drilling, and grinding tasks, this spindle module offers long-term service life, minimal maintenance downtime, and repeatable performance in demanding production settings.
