MSK076C-0300-NN-S1-UG0-NNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK076C-0300-NN-S1-UG0-NNNN is a precision IndraDyn S synchronous servomotor from the distinguished MSK IndraDyn S Synchronous Motors series, designed for demanding industrial motion control. With a compact Motor Size of 076 and a Motor Length of C, this Standard Design servomotor delivers reliable performance. Key features include Natural convection cooling for maintenance-free operation, and an advanced Optical singleturn encoder with 128 signal periods resolution via the Hiperface interface. Its primary application is in high-precision positioning systems, where accuracy and repeatability are paramount.
This MSK Series servomotor excels with a rotatable Encoder Connector capable of 240° adjustment and a Plug rotatable 240° electrical connection, simplifying installation in confined machine architectures. Equipped with 4 pole pairs, the motor achieves smooth synchronous operation at its Rated Speed Code of 0300, while providing a Maximum Torque of 43.5 Nm and supporting a Maximum Current of 32.4 A. The continuous current at standstill (100 K) is 8.1 A, ensuring controlled holds without overheating. The Plain shaft design enhances compatibility with a variety of couplings and gearboxes, while the Design: Standard configuration facilitates straightforward integration into existing automation frameworks.
Built without a holding brake, the MSK076C-0300-NN-S1-UG0-NNNN minimizes mechanical complexity and cost, while the Thermal Time Constant of 25 min indicates robust thermal stability under cyclic loads. The Natural convection cooling method enhances durability by eliminating moving cooling parts, reducing maintenance intervals and potential failure points. As a Product Type: IndraDyn S Synchronous Servomotor, it conforms to industry-standard dimensions and interfaces, ensuring broad compatibility with servo drives and motion controllers. This servomotor optimizes energy efficiency and system uptime, translating into lower operational costs and higher productivity for automated manufacturing, robotics, and material handling applications.

Frequently Asked Questions
What does natural-convection cooling mean for duty cycle and thermal behavior on MSK076C-0300-NN-S1-UG0-NNNN in S1 continuous operation?
The heat is dissipated through the frame, so airflow around the motor largely defines permissible continuous torque. Its 25-minute thermal time constant smooths temperature excursions in intermittent moves but sustained overload still requires derating or supplemental machine-side cooling.
How do the 43.5 Nm maximum torque and 32.4 A peak current of MSK076C-0300-NN-S1-UG0-NNNN translate into usable overload capability?
They define short-term acceleration torque beyond continuous limits for enabling faster indexing and recovery from process disturbances. Its drive parameterization should enforce time-at-peak constraints to protect windings and maintain magnet and bearing lifetimes.
Why are 240° rotatable encoder and power connectors advantageous on the MSK076C-0300-NN-S1-UG0-NNNN during integration?
They allow optimal cable egress and strain-relief in cramped enclosures for reducing bend stress and EMI coupling. Its orientation flexibility also shortens installation time and prevents connector clashes with adjacent axes or guarding.
Is MSK076C-0300-NN-S1-UG0-NNNN interoperable with Rexroth IndraDrive controllers and third-party systems using Hiperface?
Yes, the Rexroth specifies IndraDrive compatibility for MSK series and Hiperface is widely supported for analog Sin/Cos with a digital parameter channel. The cable sets, scaling constants and encoder ID in the drive firmware is of importance to verify.
What ingress protection level is typical for MSK IndraDyn S motors used in shop-floor environments, and what should be verified for this code?
The MSK series commonly ship with IP65-class sealing for dust and low-pressure water jets in standard configurations.
