KDA 3.3-150-3-DYD-W1

KDA 3.3-150-3-DYD-W1, Bosch Rexroth Indramat, KDA Spindle Drives brings robust performance to machine tool applications as a main spindle drive. Its compact enclosure incorporates high-stiffness construction and precision control loops, delivering responsive torque across an extensive speed range. Engineers benefit from seamless integration with motion controllers, exploiting built-in positioning features for pinpoint accuracy. The drive’s forced-air cooling scheme maintains optimal thermal conditions even under demanding duty cycles.

Designed around a DC Bus Voltage of 300 V, the KDA 3.3-150-3-DYD-W1 sustains a Rated Current of 150 A for continuous spindle operation. Its Cooling is handled by a Forced Cooled by Heatsink Blower system drawing from a AC Supply Source for Heatsink Blower of 220 VAC. Command interfaces include a Speed Command Value via Digital 16-Bit Parallel and an Aux. Interface for position commands also using Digital 16-Bit Parallel signalling. The drive accepts an Aux. Encoder Input featuring both auxiliary and synchronous inputs, compliant with AS 35 standards. Configured as Design 3 within the Product KDA family and identified as Series 3, it meets industrial benchmarks for rigidity and reliability.

Integration is streamlined with plug-and-play compatibility in CNC systems, while the forced-cooling blower enhances reliability by preventing thermal drift. High-current capability and digital command precision make this drive ideal for high-speed machining spindles. The KDA 3.3-150-3-DYD-W1’s proven track record in heavy-duty metalworking ensures continuous throughput and minimized downtime for complex milling and turning applications.
