The Bosch Rexroth Indramat KDA 3.3-100-3-LYS-W1 from the KDA Spindle Drives series is a robust main spindle drive engineered for high-precision machining. It delivers a Rated Current 100 A and maintains a stable DC Bus Voltage 300 V to power demanding spindle applications. The drive implements a Speed Command Value SERCOS - Interface for precise speed regulation and feedback. Forced cooling is provided by a Cooling Forced Cooled by Heatsink Blower system, ensuring continuous operation under heavy loads.
Built on a Design 3 architecture, the KDA 3.3-100-3-LYS-W1 drive belongs to Product KDA and follows the Series 3 family conventions, guaranteeing consistency across installations. Auxiliary connectivity is extensive, featuring an Aux. Interface Serial Interface RS 232 C for parameterization and diagnostics. It also supports an Aux. Encoder Input With Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A) to integrate secondary feedback devices. The dedicated AC Supply Source for Heatsink Blower 220 VAC ensures reliable blower power independent of the main AC bus.
This spindle drive excels in high-stiffness positioning and offers a broad speed range with continuous power handling. Its combination of advanced encoder support, SERCOS interface, and forced blower cooling makes it ideal for demanding CNC and milling spindles. Bosch Rexroth Indramat’s KDA 3.3-100-3-LYS-W1 balances performance and reliability in critical spindle drive applications.
