Product Description:
The model KDA 3.1-050-3-AY0-W1 is a main spindle drive unit used in industrial automation systems. It is designed for efficient motor control and integration into CNC systems. The main spindle drive operates optimally with a regulated DC bus voltage of 300 V.
The KDA 3.1-050-3-AY0-W1 Main Spindle Drive operates on a ± 10 V analog speed command signal. The unit delivers a continuous current output of 35 A. The main spindle drive is equipped with an auxiliary encoder input that supports both auxiliary feedback and synchronous signal processing. This input enables precise monitoring and control of spindle position and speed by integrating additional encoder signals which are essential for advanced motion synchronization, spindle orientation and high accuracy closed loop control. The blower unit (LE4) weighs 4.2 kg and ensures active cooling. The main drive itself has a weight of 16.6 kg that is suitable for mounting in standard industrial enclosures. A mechanical mounting kit is included in this model with a weight of 1.7 kg. The unit supports a permissible ambient temperature range from + 5 °C to + 45 °C under nominal conditions. The humidity classification of this spindle drive is F. This indicates the level of resistance to moisture and environmental conditions.
The KDA 3.1-050-3-AY0-W1 main spindle drive from Bosch Rexroth carries a protection category of IP10 that means it offers limited protection against solid objects but no protection against liquids. The drive system has been designed to integrate easily into modular machine concepts requiring consistent torque and dynamic drive response. These technical features make this KDA series main spindle drive compatible with complex spindle motor systems used in machining and manufacturing equipment.
