KDA 3.3-050-3-AY0-U1

KDA 3.3-050-3-AY0-U1, Bosch Rexroth Indramat, KDA Spindle Drives This high-precision spindle drive delivers exceptional stiffness and thermally stable performance for demanding CNC and milling applications. Engineered around continuous power delivery, it offers a broad speed range with dynamic positioning features that maintain accuracy under varying loads. The unit’s modular construction simplifies retrofit and upgrade processes, ensuring minimal system downtime and straightforward integration. Built on the proven KDA platform, it supports sustained operation in high-duty machining cycles with consistent torque output.

Detailed specifications underscore the drive’s robust design: it operates on a DC Bus Voltage of 300 V and provides a continuous Rated Current of 50 A. Forced cooling via a Cooling system with a dedicated AC Supply Source for Heatsink Blower at 115 VAC preserves thermal margins during extended cycles. Command interfaces include an Speed Command Value of Analog +/- 10V alongside Aux. Encoder Input with both auxiliary and synchronous signals for precise feedback. An onboard Aux. Interface option is omitted, reflecting the streamlined product layout (Product: KDA, Design: 3, Series: 3).

Integration into automated cells is seamless thanks to standardized control terminals and comprehensive documentation. The forced-cooled heatsink blower enhances reliability in high-torque regimes, reducing risk of thermal overload and extending service intervals. Ideal for high-speed spindles, the KDA 3.3-050-3-AY0-U1 drive combines rugged construction with precise control, making it a dependable choice for modern machining centers and high-performance manufacturing lines.
