Product Description:
The KDA 3.1-050-3-AYI-U1 Main Spindle Drive supports precise control and reliable operation under demanding conditions. The drive unit is suitable for installations at altitudes up to 1000 meters without derating. Its efficient design ensures durable and consistent output across diverse environments.
The Bosch Rexroth KDA 3.1-050-3-AYI-U1 main spindle drive uses a forced air cooling system to maintain thermal stability during operation. It features a rated current of 50 A that offers stable performance under full load. The power for the heatsink blower is supplied through an AC source rated at 115 V and operates at 50 – 60 Hz. The unit supports a control voltage bus consumption of 1.2 A at + 24 V load voltage and 160 mA at ± 15 V measuring voltage. This helps ensure stable control and measurement accuracy. The incremental encoder output is available in this model through the auxiliary interface that enhances feedback and operational precision. The mechanical installation is facilitated through a mounting kit which weighs 1.7 kg and allows straightforward integration into existing systems. The drive is compact and engineered for optimal alignment with high speed spindle requirements especially in automated systems. It handles electrical and mechanical integration efficiently with minimal space requirements.
The KDA 3.1-050-3-AYI-U1 main spindle drive supports safe storage and transportation between - 30 °C to + 85 °C. It is suitable for industrial use across varied climatic zones thanks to its wide temperature tolerance. Its current rating of 35 A ensures adequate power delivery to handle spindle motor loads during continuous operation. The drive's integrated auxiliary encoder input supports additional feedback channels for higher precision and synchronization. The unit is constructed to perform reliably in industrial environments requiring consistent current output and precise control feedback.
