KDA 3.1-150-3-AY0-U1

The Bosch Rexroth Indramat KDA 3.1-150-3-AY0-U1 is part of the KDA Spindle Drives series and represents a high-performance solution within the KDA product family. It delivers a Rated Current of 150 A supported by a DC Bus Voltage of 300 V and utilizes Forced cooling (heatsink blower) driven by an AC Supply for Heatsink Blower: 115 VAC to ensure thermal stability. Precision motion is enabled through an Encoder Input: Auxiliary & synchronous port and a Speed Command Signal: Analog ±10 V interface for seamless command integration. The drive features a streamlined Design: 1 enclosure, and while no Auxiliary Interface is provided, its compact footprint minimizes cabinet space.

Engineered for exceptional high stiffness and advanced positioning features, the drive accommodates an extensive speed range with continuous power output ideal for spindle applications. Its dedicated heatsink blower system rapidly removes heat during heavy-duty cycles, reducing thermal drift and extending maintenance intervals. The structure follows the series 3 designation, offering consistent mounting dimensions that simplify upgrade paths in existing machine tools. The robust analog control scheme and synchronous encoder feedback guarantee precise speed tracking and repeatability even under fluctuating loads.

Compact yet resilient, the KDA 3.1-150-3-AY0-U1 spindle drive excels in CNC milling, drilling, and high-precision grinding where reliability and uptime are critical. Its combination of Analog ±10 V speed command, dedicated 115 VAC blower supply, and straightforward installation workflow provide a turnkey solution for modern machining centers. Maintenance demands are low thanks to the forced-cooling design and absence of auxiliary interface cabling, making it ideal for high-throughput production lines.
