KDA 3.1-100-3-LQ0-U1

The Bosch Rexroth Indramat KDA 3.1-100-3-LQ0-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers robust performance with a Rated Current of 100 A and a nominal DC Bus Voltage of 300 V. Engineered for main spindle applications, it offers high stiffness, precise positioning features, and an extensive speed range under continuous power conditions. Its compact Design 1 housing integrates seamlessly into machining centers and multi-axis systems, maximizing rigidity without sacrificing footprint. Built on the reliable foundations of the Product KDA family, this drive meets the demanding dynamics of modern CNC spindles.

Thermal management is ensured through Forced Cooled by Heatsink Blower technology, powered by an AC Supply Source for Heatsink Blower of 115 VAC, guaranteeing stable operation under peak loads. Feedback integration is simplified with With Aux. Encoder Input for 1V Sinusoidal Enc. and a streamlined Without Aux. Interface option for straightforward wiring. Command and control are executed via a native SERCOS - Interface Speed Command Value channel, providing high-speed synchronization and deterministic data exchange. As a Series 3 unit, it adheres to stringent quality metrics, delivering repeatable cycle times and minimised setup variations.

In demanding machining environments where torque consistency and accelerated ramp rates are critical, this spindle drive excels in delivering smooth acceleration and deceleration profiles. Its robust forced-air cooling and encoder support enhance reliability and service life, making the KDA 3.1-100-3-LQ0-U1 a preferred choice for high-precision, high-speed spindle control in aerospace, mold making, and general tooling applications.
