Product Description:
The model KDA 2.1-050-3-AQI-U1 is a main spindle drive unit designed for precision performance in motion control systems. It operates efficiently under variable conditions and provides stable control for industrial spindle applications. This drive features forced cooling and a compact durable design for reliable integration.
This KDA 2.1-050-3-AQI-U1 main spindle drive operates with a DC bus voltage of 300 V. It delivers a continuous current of 35 A and a rated current of 50 A. The unit incorporates an auxiliary interface that includes an incremental encoder output. The cooling for the model is maintained through a heatsink blower which ensures consistent thermal management during extended operations. The heatsink blower is powered by an AC supply rated at 115 V and functions at 50 – 60 Hz frequency. The unit can withstand a wide temperature range during storage and transport from - 30 °C to +85 °C. In operational environments, it supports a maximum ambient temperature of + 55 °C with reduced nominal data. The permissible humidity rating for the model is designated as Class F that is suitable for industrial environments. It consumes 1.2 A from the + 24 V load voltage supply. These specifications enable the drive to perform consistently in a range of demanding applications requiring high current control and stable operation.
The total weight of the Bosch KDA 2.1-050-3-AQI-U1 main spindle drive is 16.6 kg that offers a robust build suitable for fixed installations. The incremental encoder output supports enhanced feedback for speed and position control. Its moderate voltage load consumption enhances energy efficiency in integrated systems. These features collectively make this KDA series drive an efficient solution for applications requiring accurate spindle motion control and stable electrical performance.
