KDA 3.3-150-3-LPD-W1

The KDA 3.3-150-3-LPD-W1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive delivers industry-leading precision and dynamic performance. Featuring high structural stiffness and advanced positioning functions, this unit supports a broad continuous speed range for demanding machining applications. The drive’s compact footprint integrates seamlessly into automated milling and turning centers, reducing cabinet space without sacrificing power density. Engineered for robustness, it ensures consistent torque delivery under heavy load transitions.

Detail-focused design elevates operational reliability: the DC Bus Voltage of 300 V and a Rated Current of 150 A provide stable power conversion for spindle or accessory motors. Thermal management relies on a Cooling system that is Forced Cooled by Heatsink Blower, with an AC Supply Source for Heatsink Blower of 220 VAC to maintain optimal junction temperatures. Motion feedback is handled via an Aux. Encoder Input configured for spindle or second motor feedback, while position commands arrive through an Aux. Interface offering Position Command Value Digital 16-Bit Parallel. Command and control utilize the Speed Command Value over a SERCOS - Interface, delivering deterministic cycle times. The drive’s Design designation of 3, Product family KDA, and Series identifier 3 consolidate platform commonality and spare parts interchangeability.

Integration into high-volume production lines is simplified by standardized electrical connections and software toolchains that support rapid parameter cloning and system diagnostics. The drive’s proven reliability under continuous duty cycles reduces maintenance intervals and minimizes unplanned downtime. Ideal for milling spindles, grinding machines, and multitasking centers, the KDA 3.3-150-3-LPD-W1 enhances throughput and process stability in modern manufacturing environments.
