KDA 3.1-050-3-D0I-U1

Product Description:

The KDA 3.1-050-3-D0I-U1 is a high-quality and versatile spindle drive developed by Bosch Rexroth Indramat. It is one of the unique KDA Spindle Drives. It is designed to operate under challenging loads. It features 22 kW power and a rated current of 50 A, which allows usage with robust motors in industrial machines such as CNC systems or automated manufacturing lines. The drive has a 3-phase 380 to 460 V AC input, and the braking chopper is integrated to ensure safe handling of the motor.

An important feature of this spindle drive is that it has an internal air-cooling system. This shows that the drive is self-cooled through the air that flows within the unit with the help of incorporated fans or blowers. It can be used to ensure that there is a stable internal temperature despite the high-power consumption of the drive. The unit requires fewer external cooling systems, is easy to mount, and takes up less space in control cabinets, making it easier to install and maintain. Cooling is done properly to prevent overheating, which may be dangerous for the motor or cause damage in the long run.

Another key feature is the configurability of the feedback type, which allows the drive to work with either a resolver or an encoder. These feedback devices assist the drive to monitor the position, speed and rotation of the motor more accurately. The advantage of an encoder as compared to a resolver is that an encoder provides very accurate digital signals and is therefore suited for high-precision control applications, whereas a resolver is more robust and capable of operating in rougher conditions. These two feedback options render the KDA 3.1-050-3-D0I-U1 versatile and flexible for various machines and applications.
