KDA 3.1-050-3-D00-W1, Bosch Rexroth Indramat, KDA Spindle Drives epitomizes the precision and robustness demanded by modern machining centers. This main spindle drive leverages a modular architecture to deliver dynamic performance across a broad speed range, combining high stiffness with advanced positioning features. It is engineered for seamless integration with CNC controllers, ensuring tight loop stability and consistent torque delivery. Built on Indramat’s legacy of reliability, this unit supports uninterrupted operation even under fluctuating loads and harsh industrial environments.
In rigorous factory tests, the drive sustains a continuous bold Rated Current: 50 A while maintaining a bold DC Bus Voltage: 300 V for sustained power output. A bold Cooling: Forced Cooled by Heatsink Blower system, powered by an bold AC Supply Source for Heatsink Blower: 220 VAC, rapidly dissipates heat to keep semiconductor junction temperatures within safe limits. The integrated bold Speed Command Value: Digital 16-Bit Parallel interface provides high-resolution velocity control with minimal jitter, while the absence of both bold Aux. Encoder Input: Without and bold Aux. Interface: Without simplifies wiring and reduces component count. The drive’s bold Design: 1 and bold Product: KDA nomenclature reflect its role as a core module within the series, optimized for direct spindle coupling.
Engineers benefit from the KDA 3.1-050’s plug-and-play compatibility with standard feedback loops, minimizing commissioning time and engineering effort. Its forced-air cooling arrangement ensures peak performance in demanding duty cycles, maximizing uptime without external chillers. Ideal for high-precision milling, drilling, or grinding applications, this spindle drive delivers consistent acceleration, high torque density, and the dependable operation needed for today’s high-throughput manufacturing lines.
