KDA 2.1-150-3-D00-U1

The Bosch Rexroth Indramat KDA 2.1-150-3-D00-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers robust performance for main spindle applications with a Rated Current of 150 A and a DC Bus Voltage of 300 V. It integrates a Digital 16-Bit Parallel Speed Command Value for high precision speed control and benefits from Forced Cooled by Heatsink Blower thermal management. Designed for continuous operation, this drive maintains high stiffness across an extensive speed range and supports precise positioning functions. The compact footprint simplifies integration into CNC machining centers and automated turning applications.

Featuring an AC Supply Source for Heatsink Blower of 115 VAC to power its dedicated cooling fan, the drive ensures consistent heat dissipation under heavy loads. The unit’s Aux. Encoder Input: Without and Aux. Interface: Without configurations streamline the design for direct spindle control, while the Design: 1 and Product: KDA identifiers affirm compatibility with existing KDA line components. Classified under Series: 2, the drive builds on proven architecture for enhanced reliability. Its heatsink blower assembly provides forced convection cooling, maintaining optimal junction temperatures even at peak current.

Engineers will appreciate the drive’s ability to sustain continuous torque output and rapid acceleration-deceleration cycles without thermal throttling. Simplified wiring and a standardized mechanical envelope accelerate installation and reduce downtime during maintenance. As a core component of high-precision milling, drilling, and grinding systems, the KDA 2.1-150-3-D00-U1 excels in demanding production environments where repeatability and dynamic response are critical.
