KDA 3.3-150-3-AYS-W1

The Bosch Rexroth Indramat KDA 3.3-150-3-AYS-W1 from the KDA Spindle Drives series combines robust construction with precise control, featuring a Rated Current of 150 A and a DC Bus Voltage of 300 V. Engineered as part of the Product KDA lineup in Design 3 and automatically identified within Series 3, this spindle drive delivers reliable power density for demanding machining tasks. Commanded via an Analog +/- 10V Speed Command Value interface, it supports fine-tuned speed regulation across a broad operational range. Cooling is managed through Forced Cooled by Heatsink Blower technology, with an AC Supply Source for Heatsink Blower of 220 VAC ensuring consistent thermal performance.

Reliability is enhanced by comprehensive feedback and connectivity options, including a serial Aux. Interface RS 232 C and integrated Aux. Encoder Input with Auxiliary and Synchronous Inputs compliant with AS 35 standards. The drive’s high stiffness design and advanced positioning features enable rapid response and minimal torsional distortion during rapid acceleration and deceleration cycles. Continuous output is sustained through efficient heat extraction and DC bus architecture, maintaining performance under variable loads and extended run-times. Industrial-grade components ensure long service life even in harsh manufacturing environments and support consistent spindle speed under peak loads.

Installation and commissioning are straightforward, with the KDA 3.3-150-3-AYS-W1 fitting standard drive cabinets and integrating seamlessly with existing Bosch Rexroth control systems. The efficient heatsink blower and robust power electronics reduce maintenance intervals, while the analog speed command and synchronous encoder inputs simplify setup and tuning. Overall, this spindle drive delivers precision, durability, and ease of integration for automotive, mold making, and general machine tool applications.
