KDA 3.3-100-3-LPI-W1

KDA 3.3-100-3-LPI-W1, Bosch Rexroth Indramat, KDA Spindle Drives is a high-performance main spindle drive designed to deliver precise motion control in demanding machining applications. With a Rated Current of 100 A and a DC Bus Voltage of 300 V, this unit provides robust continuous power for both spindle and auxiliary axes. The drive's compact Design type "3" chassis integrates core power electronics and a forced-cooling system, ensuring consistent thermal management under heavy loading. Featuring a Product designation "KDA" and belonging to the third generation Series, this spindle drive combines proven hardware with advanced feedback interfaces.

The KDA 3.3-100-3-LPI-W1 implements a dedicated AC Supply Source for Heatsink Blower rated at 220 VAC, supplying the integrated heatsink blower for reliable Cooling under full load. Dual feedback capability is provided through an Aux. Encoder Input that supports both spindle and second-motor feedback, while an Aux. Interface offers an Incremental Encoder Output for real-time position monitoring. Command and control are handled via a Speed Command Value over SERCOS-Interface, delivering deterministic synchronization and low-latency response. The modular design simplifies installation and service, and the drive's internal bus architecture supports seamless integration into multi-axis NC systems.

Engineers benefit from the drive's high stiffness and wide variable-speed range, enabling precise contouring and rapid acceleration for complex toolpaths. Forced cooling by the heatsink blower sustains performance in continuous duty cycles, minimizing thermal drift and downtime. The KDA Spindle Drive series is ideal for demanding milling, grinding, and multi-tasking centers where reliability, position accuracy, and uninterrupted throughput are paramount.
