KDA 3.1-150-3-AY0-W1

The KDA 3.1-150-3-AY0-W1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive delivers high stiffness and precise positioning across an extensive speed range. This drive leverages continuous power design to maintain consistent torque output under heavy cutting loads. Engineered for seamless integration into modern machine tools, it supports rapid acceleration and deceleration profiles without compromising stability. Its compact construction and rugged casing ensure durability in high-vibration environments.

This unit features a Rated current of 150 A on a robust DC bus voltage of 300 V, enabling sustained high-torque operation. Thermal management is handled by a Cooling method of Forced air by heatsink blower powered by a dedicated Blower supply voltage of 220 VAC, which efficiently dissipates heat during peak loads. Control inputs include a Speed command input of ±10 V analog, while precise motion feedback is enabled through Auxiliary encoder & synchronous inputs which are Supported. The drive omits an Auxiliary interface, simplifying the setup, and follows a streamlined Design 1 in the compact Model KDA3 housing.

Integration is straightforward thanks to the KDA’s standardized mounting and electrical layout, minimizing cabinet redesign. The forced-air cooling system and low-maintenance blower enhance reliability in continuous-duty applications. Ideal for high-precision spindle control in CNC machining centers, it supports long uptime and consistent performance under variable load conditions.
