MSK103B-0300-NN-S1-UG0-NNNN

The MSK103B-0300-NN-S1-UG0-NNNN from Bosch Rexroth Indramat integrates seamlessly into the MSK IndraDyn S Synchronous Motors series, offering a robust solution for high-precision motion control. This IndraDyn S Synchronous Servomotor features a continuous torque at standstill of 31.0 Nm and a continuous current at standstill of 19.0 A, with a peak maximum torque of 85.0 Nm and a maximum current of 63.0 A to handle demanding dynamic loads. The motor delivers a maximum speed of 4700 RPM and maintains optimal performance in ambient temperatures between 0 and 40°C. With a compact Motor Size of 103 and a Motor Length code B, it achieves a power-to-weight balance in a package weighing 22.5 kg. The device conforms to an IP65 protection rating, enabling installation outside control cabinets and close to operating machinery.

Performance is enhanced through precision feedback and carefully engineered electrical characteristics. The singleturn optical encoder employs Hiperface interface technology with 128 signal periods, and a rotatable 240° encoder connector, ensuring reliable position feedback in tight spaces. The winding features a Winding Code 0300 with an inductance of 8,000 mH and a resistance of 0.36 Ω measured at 20°C, providing a torque constant of 1.76 Nm/A and a voltage constant of 108 V/krpm at rated conditions. Natural convection cooling maintains thermal stability with a thermal class of 155 and a thermal time constant of 27 minutes, supporting continuous operation without auxiliary cooling. A plain shaft with integrated sealing ring protects bearings from dust and moisture, while the absence of a holding brake reduces maintenance complexity.

Reliability is inherent in the Standard design and rugged construction of the MSK103B-0300-NN-S1-UG0-NNNN. The robust shaft type and high ingress protection allow seamless integration into packaging, robotic assembly, and machine tool applications. Natural convection cooling combined with an IP65 enclosure minimizes downtime in harsh environments. The rotatable connectors and modular form factor simplify mounting and reduce installation costs. Ideal for precision positioning, automated handling, and servo-driven conveyor systems, this motor delivers consistent performance, low sound pressure (below 75 dB), and outstanding long-term durability.
