Product Description:

The MSK050B-0300-NN-S1-UP0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is used to provide tightly regulated torque and speed for automated handling, packaging, and forming stations where high positional accuracy and repeatability are required. A standard frame, keyed shaft, and rotatable 240° encoder connector allow the motor to mount on drive modules that rely on the IndraDrive family of controllers. Its synchronous design helps the drive maintain controlled motion during repeated starts, stops, and speed changes. This layout also supports installation on compact machine axes where cable routing and mounting space are limited.

The motor uses a 050 frame size and a motor length B, giving a short axial dimension for installations with limited space. Heat is removed through natural convection, so no external blower or liquid circuit is required, and the housing fins radiate losses directly to the surrounding air. A shaft with keyway delivers positive torque transmission to pulleys or couplings without relying on friction fits. The winding code 0300 matches the motor’s electrical characteristics to compatible drives, and the unit is supplied without a holding brake, so position retention during power-off must be handled by the drive or by external mechanics.

Feedback is processed through a Hiperface interface that transmits position and diagnostic data over a single hybrid cable. Inside the housing, an optical encoder reads 128 signal periods per revolution, providing fine interpolation for smooth velocity loops and stable position control. The motor uses single-turn feedback, so absolute position is referenced within one mechanical turn, while any turn-count tracking beyond that must be handled by the controller. The rotatable connector can be oriented to clear surrounding hardware and support cleaner cable routing in tight machine layouts.
