The KDA 3.3-150-3-DY0-W1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive is engineered for high-stiffness applications where precise positioning and dynamic response are critical. Featuring integrated gearing compatibility and advanced power electronics, it delivers continuous torque across an extensive speed range. The architecture supports rapid acceleration and deceleration cycles while maintaining positional accuracy under varying loads. Its compact form factor enables straightforward retrofit into CNC milling and turning centers.
Operating on a DC Bus Voltage of 300 V, the drive sustains a Rated Current of 150 A for heavy-duty spindle motors and high-inertia loads. Speed regulation is handled by a Digital 16-Bit Parallel Speed Command Value interface, and feedback is managed through the Aux. Encoder Input with auxiliary and synchronous signals per AS 35 standards. Thermal management employs Forced Cooled by Heatsink Blower cooling, fed by a dedicated AC Supply Source for Heatsink Blower of 220 VAC, ensuring stable temperature control during continuous operation. Despite its robust Design type of 3, the module streamlines wiring by omitting any Aux. Interface, enhancing signal integrity and reducing installation complexity.
Seamless integration with Bosch Rexroth motion controllers and power modules facilitates system-level diagnostics and parameter cloning, minimizing commissioning time. The KDA 3.3-150-3-DY0-W1’s robust construction ensures reliable performance in high-cycle industrial environments, reducing maintenance intervals. Ideal for advanced machining centers, it optimizes spindle control for precision, dynamic response, and maximum operational uptime.
