KDA 3.3-150-300-DP0

The Bosch Rexroth Indramat KDA 3.3-150-300-DP0 from the KDA Spindle Drives series is a high-precision spindle drive engineered for demanding industrial machining applications. Manufactured by Bosch Rexroth Indramat, this unit delivers a Rated Current of 150 A and a DC Bus Voltage of 300 V, providing robust continuous power for high-stiffness, high-accuracy spindle control. Featuring a Digital 16-Bit Parallel Speed Command Value, it allows precise positioning and rapid response over an extensive speed range, making it ideal for advanced CNC spindle operation and multiaxis synchronization.

The KDA 3.3-150-300-DP0 excels with its forced cooling system: it is Forced Cooled by Heatsink Blower to maintain optimal thermal performance under continuous load. An auxiliary encoder interface (labeled With for Spindle or Second Motor Feedback) supports high-resolution feedback for both spindle and secondary motor applications, enhancing closed-loop position control. The AC Supply Source for Heatsink Blower is factory assigned for seamless integration, while the design variant 3 in the KDA product line ensures consistent component compatibility. Its compact yet rugged construction is tailored for harsh production environments and guarantees reliable operation over extended service cycles.

Beyond raw power and precision, this spindle drive offers exceptional compatibility and durability. The absence of auxiliary interface components (Aux. Interface: Without) reduces potential failure points, and the modular KDA design (Product: KDA, Series: 3) streamlines installation and maintenance. The integrated heatsink blower cooling system optimizes efficiency, minimizing downtime due to overheating and enabling sustained high-speed operation. In industrial settings, the KDA 3.3-150-300-DP0 enhances productivity by delivering consistent torque, precise positioning, and reliable continuous service, yielding improved machining throughput and reduced maintenance overhead.
