Product Description:
The Bosch Rexroth KDA 3.1-150-3-L00-U1 Main Spindle Drive is a power dense unit engineered for spindle motor control in industrial automation systems. It ensures efficient torque and speed regulation. The unit is designed for robust environments and continuous industrial duty.
This KDA 3.1-150-3-L00-U1 spindle drive unit operates with a rated current of 150 A and utilizes a forced cooling system to maintain thermal efficiency during extended operation. The speed command is transmitted via a SERCOS interface that enables reliable digital communication between control systems. The drive supports installation at elevations up to 1000 meters above sea level. A mechanical mounting kit (M1-KD) weighing 1.7 kg provides stable and secure installation. The permissible humidity level of this drive unit is F that allows the unit to function in demanding industrial atmospheres. The system’s cooling configuration includes a blower unit (LE4) with a weight of 4.2 kg. The permissible maximum operating ambient temperature is + 55 °C provided that performance parameters are adjusted accordingly. This allows the unit to operate in higher temperature conditions when required. The drive is structurally compact yet powerful that is suitable for modern CNC machines or motor control cabinets where reliability and precision are critical.
The KDA 3.1-150-3-L00-U1 spindle drive unit is well suited for machines requiring scalable drive solutions. Its 300 V DC bus voltage and 90 A continuous current allow it to handle heavy spindle loads. The drive's built in ± 15 V measuring voltage with 160 mA output is suitable for interfacing with feedback systems. An integrated blower powered by a 115 V AC supply maintains optimal temperature and prolongs component life. The drive is a robust dependable solution for precise and adaptable spindle control.
