The Bosch Rexroth synchronous servomotor R911309794 (MSK070C-0150-NN-M2-UG1-RNNN) features natural convection cooling and a plain shaft with a force-fit hub connection. It incorporates a KTY84 temperature sensor for thermal monitoring up to 140°C housing temperature and is designed with an IP65-rated flange for ingress protection. The unit includes an electrically-released 23 Nm holding brake and multiturn absolute optical encoder (EnDat 2.1, 2048 signal periods, 240° rotatable connector) for precise position feedback. With a continuous standstill current of 4.6 A (100 K), continuous standstill torque of 14.5 Nm, maximum current of 16.4 A, and maximum torque of 33.0 Nm, the motor is balanced to DIN 42955 for elevated concentricity and reliability. Winding inductivity is rated at 34,900 mH. Storage conditions require a clean, dry location away from direct sunlight.

In which technical applications is MSK070C-0150-NN-M2-UG1-RNNN motor commonly used?

The MSK070C-0150-NN-M2-UG1-RNNN motor is widely applied in CNC milling, packaging automation, and robotics. Its multiturn encoder supports high-precision positioning tasks.

How does maximum current of 16.4 A influence its drive selection?

The motor’s current rating determines the compatible drive amplifier size. Using a matched drive ensures efficient torque output and prevents overheating.

Why is continuous torque at 100 K significant for MSK070C-0150-NN-M2-UG1-RNNN motor?

The MSK070C-0150-NN-M2-UG1-RNNN motor continuous torque rating ensures stable long-duration operation. It prevents thermal overload in high-duty cycles.

What role does natural convection cooling play in this servomotor?

The cooling method dissipates heat passively without fans. This reduces maintenance needs and improves reliability in sealed systems.

Why is the winding inductivity of 34,900 mH important in MSK070C-0150-NN-M2-UG1-RNNN motor?

The high inductivity reduces ripple current and improves smooth torque delivery. This enhances precision during low-speed operation.
