The Bosch Rexroth Indramat MSK050B-0300-NN-S1-UG1-NNNN servomotor from the MSK IndraDyn S Synchronous Motors series by Bosch Rexroth Indramat combines robust construction with precise motion control capabilities. Featuring natural convection cooling and an integrated holding brake that is electrically released, this unit ensures stable performance without the need for auxiliary cooling systems. With a compact motor size of 050 and a motor length code B, it is engineered to deliver reliable torque output in space-constrained installations. Its primary function is to provide high-precision, dynamic response in demanding automated applications such as assembly lines, robotics, and machine tools.
This IndraDyn S Synchronous Servomotor is equipped with an advanced optical encoder using a singleturn design and a Hiperface interface, offering 128 signal periods of resolution for accurate position feedback. The encoder connector is rotatable through 240°, simplifying wiring and setup. Rated for a continuous torque at standstill of 3.4 Nm at 100 K with a continuous current at standstill of 2.0 A, the motor can sustain precise positioning without drift. Under dynamic conditions it can reach a maximum torque of 9.0 Nm with a maximum current of 7.2 A. The high winding inductivity of 76,400 mH ensures smooth current flow and reduced electrical noise, while the plain shaft design optimizes mechanical coupling for a variety of gearboxes and couplings.
Built to a standard design that emphasizes compatibility, the MSK050B-0300-NN-S1-UG1-NNNN integrates seamlessly into existing Bosch Rexroth drive systems and industrial controllers. The with holding brake feature provides a holding brake torque of 6 Nm, maintaining load position safely during power interruptions. Natural convection cooling enhances system durability by eliminating moving cooling parts and reducing maintenance requirements. This servomotor’s efficiency and precision make it ideal for continuous operation in high-duty-cycle environments, meeting stringent industrial reliability standards. By leveraging its robust braking, high-resolution feedback, and natural cooling, the MSK050B-0300-NN-S1-UG1-NNNN delivers improved uptime, reduced energy consumption, and greater process control in automated manufacturing settings.
