Product Description:
The MSK076C-0450-NN-S1-UG0-NNNN belongs to the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. It is an AC servo motor intended for closed-loop positioning, speed, and torque control on automated axes such as pick-and-place gantries, form-fill-seal stations, or tool changers. By integrating a high-resolution feedback device and drive-matched windings, the motor converts electrical power from servo amplifiers into regulated mechanical rotation for precise industrial motion tasks. This operating principle allows the axis to respond accurately to changing command values during acceleration, positioning, and speed regulation.
Cooling is handled by natural convection, eliminating fans and making thermal performance dependent on free airflow around the housing. Because cooling is passive, unobstructed air circulation around the housing is important for steady operation. Frame size 076 sets the flange diameter and bolt circle, while length code C extends the magnetic core to increase continuous torque within the same mounting pattern. Winding code 0450 identifies the wire gauge and turns per phase so current, voltage, and impedance match IndraDrive power modules. The feedback link uses the Hiperface protocol through a rotatable 240° connector, which helps route cables in tight cabinets. Standard design trim means the paint, insulation, and hardware follow the base MSK configuration. The motor is supplied without a holding brake, so external mechanical latches or drive torque must secure the load when power is removed.
An optical sensor disc delivers single-cycle position data. The encoder is a single-turn device that resets position after one revolution, yet it still resolves the shaft into 128 signal periods for fine interpolation inside the drive. Mechanical power exits through a plain shaft, allowing couplings or pulleys to seat directly without keyways or splines. This arrangement is well suited to servo axes that need direct shaft coupling, accurate feedback processing, and a compact motor package.
Frequently Asked Questions about MSK076C-0450-NN-S1-UG0-NNNN:
Q: What type of shaft does the MSK076C-0450-NN-S1-UG0-NNNN servomotor feature?
A: This model uses a plain shaft configuration, which allows for direct and smooth coupling to compatible machinery.
Q: How is the MSK076C-0450-NN-S1-UG0-NNNN servomotor cooled?
A: The motor is cooled by natural convection, operating efficiently without the need for forced airflow.
Q: Does the MSK076C-0450-NN-S1-UG0-NNNN come with a holding brake?
A: This motor does not include a holding brake, so it does not provide braking functionality when stationary.
Q: What encoder specifications does the MSK076C-0450-NN-S1-UG0-NNNN have?
A: The encoder is a singleturn optical type with Hiperface interface and a resolution of 128 signal periods.
Q: What is the range of motion for the encoder connector on the MSK076C-0450-NN-S1-UG0-NNNN?
A: The MSK076C-0450-NN-S1-UG0-NNNN features a rotatable encoder connector with a movement range of 240°.
