Product Description:

The MSK070C-0150-NN-M2-UP1-RNNN synchronous servo motor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. In multi-axis automation, it serves as a high-precision drive element, delivering commanded motion profiles to linear stages, rotary tables, or articulated joints with closed-loop position control. Its compact 070 frame suits applications where cabinet space is limited, and its increased concentricity reduces runout to support accurate positioning during dynamic duty cycles.

Cooling is handled by natural convection, so heat is transferred from the housing to the surrounding air without forced airflow. Position data are transmitted through an EnDat2.1 serial interface, enabling digital bidirectional exchange of motor ID and diagnostics with the drive. The encoder provides 2048 signal periods per mechanical revolution, and controller interpolation supports very fine positioning. Because the sensing principle is optical, signal quality remains stable over temperature changes and vibration. The motor uses a multi-turn absolute encoder, so true position is retained after power loss without homing. A rotatable 240° connector lets the feedback cable exit in the preferred direction, which helps in tight cabinets.

The integrated holding brake develops 23 Nm of static torque and is released electrically, allowing gravity-loaded axes to stay locked during shutdown until drive power is restored. Mechanical energy is transmitted through a shaft with a keyway, giving a positive connection to pulleys, couplings, or gearboxes. The electromagnetic characteristics follow winding code 0150, which indicates the voltage constant and rated current pairings used by IndraDrive parameter sets. The motor has axial length code C, which helps verify that it fits available installation space while still providing the inertia needed for smooth speed control.
