Product Description:

The MSK040C-0450-NN-M1-UG1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and included in the MSK IndraDyn S Synchronous Motors series. It couples directly to a compatible Rexroth drive controller, converting controlled current into precise shaft motion for pick-and-place axes, feeders, and compact gantries. The motor combines fast servo response with a sealed housing for use in tightly packed automation equipment where accurate positioning and repeatable starts and stops are required. Integrated feedback and braking functions support controlled motion during operation and secure standstill behavior when motion must stop.

Thermal management is handled through natural convection, allowing heat to leave the housing without fans or liquid circuits in vertical or horizontal mounting positions. A factory-installed, electrically released brake supplies 4 Nm of static torque so the axis can hold position during power loss or emergency stops. Position feedback is routed through the Hiperface serial interface, and the optical reader scans 128 signal periods per mechanical revolution to generate fine incremental data for the drive. Because the scanning principle is optical, the feedback system is not affected by magnetic stray fields that may be present in compact machinery. The drive can use this encoder information to correct speed and position errors throughout the motion cycle.

The feedback connector is field-orientable and can be turned through a 240° rotation to simplify cable routing in tight cabinets or along crowded machine frames. Absolute position is retained over multiple shaft turns through a multi-turn absolute measuring method, so the axis can recover position after power cycling without a return move. A plain shaft supports backlash-free coupling with clamp hubs or collets, while winding code 0450 matches the motor’s electrical behavior to compatible IndraDrive amplifiers. The 040 frame size with C-length stator gives the motor a slim profile that fits compact axes while still supporting responsive acceleration and controlled servo operation.
