The Bosch Rexroth Indramat MSK050B-0600-NN-M1-UG0-NNNN servo motor from the MSK IndraDyn S Synchronous Motors series delivers precise motion control and high dynamic performance for industrial automation applications. It features a peak torque of 9 Nm and a maximum speed of 6000 rpm, enabling rapid acceleration and deceleration profiles. The integrated Hiperface encoder interface provides accurate feedback with 128 signal periods, supporting closed-loop operation and position accuracy. Designed as a standard servomotor, it employs natural convection cooling and a plain shaft for straightforward mechanical integration. This motor’s compact form factor and robust design ensure reliable operation in a wide range of automated systems.
Detailed electrical and mechanical characteristics define the motor’s performance envelope. It achieves a continuous standstill torque of 3.0 Nm at 60 K and 3.4 Nm at 100 K, under respective rated currents of 3.7 A and 4.2 A. The peak current capability of 14.8 A supports high-torque events, while the rotor’s moment of inertia of 0.00028 kg·m^2 ensures responsive dynamic behavior. Winding inductivity measures 19.9 mH, and the thermal time constant of 8 minutes guarantees controlled temperature rise under sustained loading. The motor’s electrical connection utilizes a 240° rotatable plug and encoder connector, allowing flexible cable routing in confined installations.
Operational resilience is provided by an IP65 protection class according to IEC 60529, safeguarding against dust and water ingress. The ambient temperature operating range spans 0 to 40 °C, and the insulation class of 155 per DIN EN 60034-1 ensures electrical reliability at elevated temperatures. Discharge capacitance of 2.1 nF contributes to stable EMC performance, while sound pressure levels remain below 75 dB[A] for quieter operation in factory environments. With a total weight of 4 kg and a motor size designation of 050 and length B, the unit offers a favorable power-to-weight ratio for space-constrained machinery. The design omits a holding brake to minimize complexity and reduce maintenance requirements.
System integrators will appreciate the servo motor’s full compatibility with Bosch Rexroth IndraDrive and IndraDyn S platforms, enabling seamless commissioning and advanced drive features. The Hiperface encoder interface supports high-resolution feedback, minimizing the need for additional signal processing. Its natural convection cooling simplifies cabinet design by reducing reliance on external fans, and the rotatable connectors facilitate tidy cable management. This combination of high torque, compact size, and robust protection makes the MSK050B-0600-NN-M1-UG0-NNNN ideal for packaging machinery, pick-and-place robots, conveyor systems, and other precision automation tasks.
