Product Description

Using state-of-the-art technology, Bosch Rexroth has been able to consistently deliver the best range of products in the drive and control unit market of the world. With such qualities as high functionality, wide performance range, cost efficiency and improved safety, these products set new standards in drive technology. The IndraDyn S system by Bosch Rexroth is made up of components designed by the company to highlight these features. A family of servo motors in this system is the MSK family. MSK servo motors are versatile synchronous servo motors used as rotary main and servo drive motors in several industrial applications.

The MSK050B-0300-NN-S3-UP1-NNNN is a synchronous servo motor of the Rexroth IndraDyn S system that belongs to the MSK family. It is a B-length motor with a frame size designated as 050. Detection of the motor position is done by an integrated Singleturn Hiperface capacitive encoder with 16 signal periods and its holding brake has a holding torque of 6 Nm. The MSK050B-0300-NN-S3-UP1-NNNN is a self-cooling motor that employs natural convection for the dissipation of heat to the ambient air. It can reach a maximum velocity of 4300 rotations per minute with a maximum current rating of 7.2A.

The moment of inertia of the rotor in the MSK050B-0300-NN-S3-UP1-NNNN is 0.00028 kgm² and its thermal time constant is 8 minutes. It generates a maximum torque of 9.0 Nm at a maximum current of 7.2A. At 20^oC, its torque constant and voltage constant values are 1.80 Nm/A and 111.0 V/1000min^-1 respectively. For this motor to continue to operate optimally, the ambient temperature at its site of use must be within limits of 0^oC and 40^oC.
