Product Description:
The MSK050C-0450-NN-M1-UG1-NNNN servomotor is built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts electrical drive commands into controlled rotary motion for positioning axes, pick-and-place heads, and other precise industrial automation tasks. The unit employs a permanent-magnet rotor and integrated encoder to provide accurate feedback and consistent torque in compact machine layouts. This arrangement supports repeatable speed and position control in equipment that must respond quickly during continuous automated operation.
The motor relies on natural convection for heat removal, so enclosure airflow and mounting orientation must allow rising air to carry thermal energy away without external fans. A 240° rotatable encoder connector lets harnesses exit through a wide arc, simplifying cable routing in tight cabinets. Position data travels over the Hiperface bus, allowing digital feedback exchange between the motor and drive. Inside the feedback unit, an optical scanning system divides each mechanical rotation into 128 signal periods, supplying fine incremental information that the drive can interpolate for precise position control.
The encoder stores absolute multi-turn data, and its multi-turn absolute design preserves position even after power loss, eliminating homing cycles at startup. During power-off holding, an electrically released brake applies 6 Nm of torque, keeping the shaft fixed against moderate loads until drive current returns. The motor frame corresponds to size 050, and the plain shaft transfers torque without keyways to reduce stress on mating components. This shaft is ground for use with clamping hubs or shrink disks, while the C length and 0450 winding suit medium-duty servo axes that need a balance of continuous torque, speed, and inertia.
