KDA 3.3-050-3-D00-U1

KDA 3.3-050-3-D00-U1, Bosch Rexroth Indramat, KDA Spindle Drives deliver precision spindle control with high stiffness and a broad speed range. This main spindle drive features a Rated Current of 50 A and a DC Bus Voltage of 300 V, ensuring robust torque delivery and stable energy conversion. The drive's integrated heat sink blower provides forced cooling to maintain optimal thermal performance under continuous load. A Digital 16-Bit Parallel Speed Command Value interface offers high-resolution setpoint input for precise spindle speed regulation.

The KDA 3.3-050-3-D00-U1 is engineered with an AC Supply Source for Heatsink Blower of 115 VAC to power its cooling system without auxiliary drives. With a Cooling method that is Forced Cooled by Heatsink Blower, the drive maintains junction temperatures within safe limits even under heavy duty cycles. The device's Aux. Encoder Input and Aux. Interface are both specified as Without, simplifying installation where external feedback loops are not required. Built on a Design code 3 platform and identified by the Product name KDA, this drive combines rugged mechanical construction with advanced electronics.

Integration is streamlined through standard connection schemes and a compact package that fits into existing spindle drive cabinets. Reliability is enhanced by active thermal management and a robust control architecture derived from Bosch Rexroth Indramat’s proven industrial lineage. Ideal for CNC machining centers, milling spindles, and high-speed milling applications, the KDA 3.3-050-3-D00-U1 ensures consistent performance and low lifecycle costs across demanding production environments.
