KDA 3.1-150-3-AYD-W1

The Bosch Rexroth Indramat KDA 3.1-150-3-AYD-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat is a robust main spindle drive engineered for high-stiffness applications and precise positioning. This drive delivers a rated current of 150 A at a DC Bus Voltage of 300 V, enabling continuous power over an extensive speed range. Housed in a compact Design 1 enclosure, it seamlessly integrates into automated machining centers and CNC spindles. As part of the Product Family KDA with a Series Number 3, its construction emphasizes durability and long service life under heavy-duty conditions.

The drive’s control and feedback interfaces ensure accurate motion control: an Auxiliary Interface provides digital 16-bit parallel position commands, while dual-mode Encoder Input supports both auxiliary and synchronous operation. Speed regulation is handled via a Speed Command Input of Analog ±10 V, offering smooth acceleration and deceleration profiles. Thermal management is achieved through forced air cooling via a heatsink blower, powered by a dedicated Heatsink Blower AC Supply of 220 VAC. These features work in concert to maintain optimal operating temperatures, reduce thermal drift, and extend component longevity.

Designed for seamless integration, the KDA 3.1-150-3-AYD-W1 spindle drive offers high rigidity, precise speed control, and reliable performance in milling, drilling, and grinding applications. Its combination of advanced interface options, robust cooling, and continuous high-current capability makes it ideally suited for demanding production environments where accuracy and uptime are critical.
