Product Description:

The Bosch Rexroth Indramat MSK050C-0300-NN-M1-UG1-NNNN belongs to the MSK IndraDyn S Synchronous Motors series. It is used as a servomotor for precise positioning and velocity control in industrial automation, where closed-loop encoder feedback supports accurate motion and stable response to command changes. The C-length frame places the motor in a compact section of the range, making it suitable for handling axes, pick-and-place stations, and packaging equipment. That format fits machines that need responsive rotary motion without taking up unnecessary installation space around the axis.

The standard housing uses natural convection cooling, so heat is removed by ambient air without external blowers or liquid circuits. This cooling method also avoids auxiliary fan hardware, which helps keep the surrounding machine layout simple. A rotatable 240° encoder connector helps route cables when the motor is mounted in confined machine areas or near guarding and support plates. Position data are transmitted through the Hiperface interface, and the feedback module provides 128 signal periods per mechanical revolution. The encoder uses an optical sensing element for fine interpolation, giving the controller detailed position updates during low-speed and indexing moves. Its multiturn absolute design retains revolution information through power cycles, so homing after shutdown is not required.

For load retention when power is removed, the motor includes an electrically released holding brake. The brake provides 6 Nm of static torque for vertical or indexing axes that need the shaft to remain fixed at standstill. A plain shaft supports backlash-free clamping with shrink or friction couplings, which helps reduce mechanical play in servo applications. The motor is built in size 050, and winding code 0300 identifies the electrical data used for matching the motor with compatible drive settings. The brake and shaft arrangement suit compact axes that use clamping hubs instead of keyed couplings.
