KDA 3.3-150-3-DP0-W1

The Bosch Rexroth Indramat KDA 3.3-150-3-DP0-W1 from the KDA Spindle Drives series combines precision engineering with high-power capabilities. It delivers a Current Rated of 150 A and sustains a Continuous Current of 90 A to meet demanding spindle drive requirements. Operated at a Rated Voltage of 300 V, the controller maintains stable performance across its operating envelope. Integration of a Rated Connection Voltage for attached Blower: AC 50–60 ensures consistent forced-cooling efficiency for uninterrupted operation.

The drive controller supports advanced motion control via a Speed Command Value of Digital 16-Bit Parallel, enabling microstep-level positioning accuracy. Its Aux. Encoder Input: With for Spindle or Second Motor FeedbackAux. Interface1 provides redundant feedback pathways for enhanced reliability. Designed within Series 3 architecture and sported in a uniform Design 3 housing, it aligns with existing KDA system footprints. Forced cooling is achieved through a dedicated heatsink blower, maintaining core temperatures even under sustained torque loads.

Engineered for high stiffness and rapid dynamic response, this spindle drive excels in applications requiring tight position control and wide speed ranges. Its robust cooling scheme and multiple feedback interfaces minimize torque ripple and thermal drift, ensuring consistent cycle-to-cycle repeatability. The result is a versatile drive solution ideal for machining centers, grinders, and precision milling operations.
