KDA 2.1-050-3-LYS-U1

The Bosch Rexroth Indramat KDA 2.1-050-3-LYS-U1 from the KDA Spindle Drives series combines precision engineering and rugged reliability in a compact package. Designed as part of the Product model KDA Series 2, this main spindle drive delivers a rated current of 50 A and maintains a stable DC bus voltage of 300 V for continuous high-torque performance. Integration is streamlined via the SERCOS speed command interface and a versatile RS-232C serial auxiliary interface, while the auxiliary encoder inputs support both auxiliary and synchronous feedback. Built for harsh industrial environments, the unit features forced cooling via a heatsink blower powered by a dedicated 115 VAC heatsink blower AC supply.

High stiffness and precise positioning are inherent to the rugged Design 1 chassis, which accommodates extensive speed ranges and provides continuous power without compromise. The heatsink blower's airflow management ensures optimal thermal regulation, preventing overheating even under peak loads. Thanks to the SERCOS interface, real-time communication and speed command values are managed with microsecond accuracy. Auxiliary encoder inputs facilitate synchronization in multi-axis setups, enhancing motion control for demanding spindle applications.

Compact yet robust, the KDA 2.1-050-3-LYS-U1 is well suited for CNC machining centers, grinders, and high-speed drilling systems where reliability is paramount. Its combination of high current capacity, dedicated cooling infrastructure, and advanced feedback interfaces ensures sustained performance in continuous-duty cycles. This spindle drive represents a versatile solution for precision machining tasks that demand both power density and thermal stability.
