Product Description:

The MSK076C-0450-NN-M3-UP0-NNNN servomotor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. This synchronous servomotor provides closed-loop torque and position control for packaging lines, pick-and-place actuators, and indexing stations, linking directly to a Rexroth drive to move loads precisely within automated production cells. It also fits multi-axis gantries and presses where fast response, accurate positioning, and compact dimensions are required. In these applications, the motor converts drive commands into controlled rotary motion for repeatable cycle operation.

Within the 076 frame and C length class, the unit relies on natural convection to move heat from the stator housing to ambient air, eliminating fans. Its protection rating of IP65 seals the enclosure against dust ingress and low-pressure water jets, so the motor can be mounted close to process equipment. Operation is permitted in ambient temperatures from 0–40 °C, which suits typical plant-floor conditions. For position feedback, the unit uses the Hiperface digital interface, and its encoder generates 16 signal periods per mechanical revolution so the drive can interpolate position precisely. A rotatable 240° connector lets the feedback cable exit in different directions, which helps in tight installation spaces. The housing follows the standard design profile and uses winding code 0450 for compatibility with common IndraDrive power modules.

The encoder uses a capacitive sensor that resists magnetic stray fields and vibration. Its multi-turn absolute design tracks full shaft rotations without battery backup, so homing routines are unnecessary after power loss. Mechanical power is transferred through a shaft with a keyway, which provides positive torque transmission to pulleys or couplings. Insulation system class 155 withstands winding temperatures up to 155 °C and supports the thermal limits expected by the motor design. Because the motor is supplied without a holding brake, vertical loads must be secured by external mechanisms when power is removed.
