KDA 3.3-150-3-LY0-W1

The Bosch Rexroth Indramat KDA 3.3-150-3-LY0-W1 from the KDA Spindle Drives series combines precision engineering and robust performance in a compact 3-axis design. This Main Spindle Drive delivers a Rated Current of 150 A and a DC Bus Voltage of 300 V to support demanding spindle applications. Featuring a Speed Command Value via SERCOS Interface, the drive ensures seamless digital communication and precise rotational control. The unit’s Design 3 architecture and product designation KDA reflect its suitability for high-dynamic positioning tasks with continuous power delivery.

Engineered for reliable thermal management, the drive employs Forced Cooling by Heatsink Blower technology backed by a dedicated AC Supply Source for Heatsink Blower at 220 VAC. Auxiliary connectivity includes Aux. Encoder Input with Auxiliary and Synchronous Inputs (AS 35 and Speed Command Value = A), while maintaining a streamlined configuration without an Aux. Interface. The balanced integration of cooling, digital encoder feedback, and high-current power stages ensures stable operation across wide speed ranges. With a Series 3 platform, maintenance and part replacement follow a consistent pattern, reducing downtime in automated manufacturing lines.

Optimized for spindle control, the KDA 3.3-150-3-LY0-W1 excels in applications requiring high stiffness, rapid acceleration, and precise positioning. Its extensive speed range coupled with constant torque output makes it ideal for milling, grinding, and high-speed machining centers. Backed by Bosch Rexroth Indramat’s industrial heritage, this spindle drive delivers dependable performance for advanced CNC and robotics installations.
