MSK070C-0450-NN-M1-UP1-NSNN

The Bosch Rexroth Indramat MSK070C-0450-NN-M1-UP1-NSNN from the MSK IndraDyn S Synchronous Motors series combines compact design and rugged construction into a high-performance IndraDyn S Synchronous Servomotor. This Motor Size 070 frame is built to the Standard and Explosion Protection design standard, featuring a Motor Length C housing rated to IP65. Power and feedback connectivity are simplified by 240° rotatable encoder connectors, while the internal natural convection cooling method eliminates the need for auxiliary fans. A robust shaft with keyway ensures secure coupling to gearboxes or driven axes.

The MSK070C-0450-NN-M1-UP1-NSNN is equipped with an optical multiturn absolute Hiperface encoder, providing 128 signal periods per revolution and accurate angular positioning across 4096 revolutions. The stator winding yields a continuous torque at standstill of 14.5 Nm with a continuous current at standstill of 13.7 A, while dynamic operation peaks at maximum torque of 33.0 Nm under a maximum current of 36.9 A. A heavy-duty electrically-released holding brake is integrated, delivering 23 Nm holding torque and response times under 35 ms on connection. With a winding inductivity of 4,000 mH, the motor maintains smooth current regulation even under rapid cycle demands.

Installation and commissioning benefit from the motor’s consistent mechanical footprint across the MSK range and standardized interface protocols. Ambient operating capability spans 0 to 40 °C without derating, with safe output reduction up to 55 °C, while altitude derating begins above 1,000 m. Maintenance intervals are extended by the absence of forced air components, making the MSK070C-0450-NN-M1-UP1-NSNN an ideal choice for hazardous-area applications, precision robotics, and continuous-duty process machinery.
