KDA 3.3-050-3-LP0-W1

The Bosch Rexroth Indramat KDA 3.3-050-3-LP0-W1 is a high-performance spindle drive in the distinguished KDA Spindle Drives series. Manufactured by Bosch Rexroth Indramat, this drive delivers a Rated Current of 50 A and operates on a DC Bus Voltage of 300 V to ensure robust, continuous power delivery. Engineered for precision machining and high stiffness applications, it offers extensive speed range control and positioning features that make it ideal for main spindle drive tasks in demanding industrial environments.

Incorporating advanced technical specifications, the KDA 3.3-050-3-LP0-W1 utilizes a 220 VAC AC Supply Source for Heatsink Blower to maintain optimal thermal management under sustained load. Cooling is handled by a Forced Cooled Heatsink Blower, ensuring stable operation even during prolonged cycles. The drive provides an Aux. Encoder Input with feedback capability for spindle or second motor, enabling closed-loop control and enhanced positioning accuracy. While it comes Without Aux. Interface, it compensates with a dedicated SERCOS - Interface Speed Command Value, offering seamless integration with digital motion control networks. The drive’s Design 3 architecture within the Product KDA family reflects a rugged, modular construction for straightforward installation and maintenance.

Built to withstand industrial rigors, the KDA Main Spindle Drive supports high stiffness and reliability through its forced cooling and robust DC bus design. Its compatibility with standard SERCOS protocols and encoder feedback systems ensures smooth communication with CNC controllers and automation networks. The absence of an auxiliary interface reduces complexity while the integrated encoder input maintains precise speed and torque regulation. Ideal for CNC lathes, milling centers, and multi-axis machining, the KDA 3.3-050-3-LP0-W1 enhances operational efficiency, minimizes downtime, and delivers consistent spindle performance across a wide range of manufacturing applications.
