KDA 3.3-100-3-A0D-U1

The Bosch Rexroth Indramat KDA 3.3-100-3-A0D-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat is engineered as a high-performance main spindle drive. It features a Rated Current of 100 A and a DC Bus Voltage of 300 V, delivering continuous power across a broad speed range. The unit’s Design 3 architecture supports precise motor control with robust Product KDA heritage. Its compact form factor integrates seamlessly into machine tool environments, providing exceptional stiffness and positioning accuracy.

Reliability and control are enhanced by a Cooling method Forced Cooled by Heatsink Blower with an AC Supply Source for Heatsink Blower of 115 VAC, ensuring thermal stability under sustained loads. Command interfaces include a Speed Command Value of Analog +/- 10V input for smooth speed regulation and a high-speed Aux. Interface: Position Command Value Digital 16-Bit Parallel for precise position feedback. Notably, the drive accepts an Aux. Encoder Input: Without encoder option, simplifying integration where encoder-less control is sufficient. The standardized Series 3 platform also streamlines maintenance and spare-part management.

Optimized for CNC milling and grinding applications, this spindle drive excels in dynamic response and torque control. Its forced-cooled heatsink blower design minimizes temperature-induced drift, maintaining consistent performance during long production cycles. The Bosch Rexroth Indramat KDA 3.3-100-3-A0D-U1 is therefore ideal for high-precision machining centers requiring reliable, high-stiffness spindle control.
