KDA 3.2-050-3-AQ0-W1

KDA 3.2-050-3-AQ0-W1 from Bosch Rexroth Indramat is a high-performance unit in the KDA Spindle Drives series designed for demanding spindle applications. This main spindle drive combines robust construction with precise positioning features to deliver a broad speed range and continuous power output. Its compact form factor supports integration into machine tool axes where space is limited but rigidity is critical. Built on Indramat’s proven architecture, the KDA 3.2-050-3-AQ0-W1 ensures consistent repeatability and dynamic response for high-speed machining tasks.

In operation, the drive accepts a DC Bus Voltage of 300 V and supplies a continuous Rated Current of 50 A, enabling sustained torque delivery under variable load. A dedicated AC Supply Source for Heatsink Blower at 220 VAC powers the forced-cooling system, while the Cooling concept uses a heatsink blower to maintain optimal thermal performance in harsh environments. Speed setpoints are managed via an Analog +/– 10V Speed Command Value, and the unit features an Aux. Encoder Input for 1V Sinusoidal Enc. feedback. Although shipped Without an Aux. Interface, the drive’s modular design (Design 2) simplifies the addition of optional I/O cards and communication modules.

Engineers benefit from rapid commissioning thanks to a straightforward wiring scheme and standard control signals, reducing integration time in CNC systems. The drive’s forced-air cooling ensures high reliability and long-term stability, even under continuous operation. Ideal for milling, drilling, and high-speed turning applications, the KDA 3.2-050-3-AQ0-W1 blends precision, power density, and ruggedness for advanced machine tool spindles.
