KDA 3.3-150-3-APS-W1

The Bosch Rexroth Indramat KDA 3.3-150-3-APS-W1 spindle drive from the Bosch Rexroth Indramat KDA Spindle Drives series delivers high stiffness and precise positioning across an extensive speed range. Engineered as a main spindle drive, the KDA 3.3-150-3-APS-W1 ensures continuous power output under demanding machining cycles. Its robust construction supports sustained heavy-duty operation while maintaining tight tolerances. Users benefit from advanced feedback and drive features optimized for high-performance spindle applications.

Featuring a DC Bus Voltage: 300 V, the unit draws a Rated Current: 150 A for superior torque delivery. Cooling is managed via a Forced Cooled by Heatsink Blower system powered from an AC Supply Source for Heatsink Blower: 220 VAC, ensuring thermal stability under peak loads. The drive accepts an Analog +/− 10V Speed Command Value for fine speed regulation, while dual feedback options include an Aux. Encoder Input supporting spindle or secondary motor feedback. Communication and configuration are handled over an Aux. Interface: Serial Interface RS 232 C, and the compact Design 3 housing integrates seamlessly into existing control cabinets.

The KDA 3.3-150-3-APS-W1 excels in integration thanks to its compact footprint and standard interface set, simplifying upgrades on CNC machines or automated spindles. Its forced-cooling mechanism and high current capacity deliver reliable performance even in continuous-duty cycles. This drive is ideal for precision machining, milling, and drilling applications where consistent speed control and system uptime are critical.
