The Rexroth Indramat MPN R911322090 (MSK071D-0450-FN-M1-UG2-NNNN) is an IndraDyn S synchronous servomotor with liquid cooling and a rotatable 240° encoder connector. The motor features an optical multiturn absolute encoder (Hiperface interface) with 128 signal periods, and a standard plain shaft. The unit integrates an electrically released holding brake rated at 30 Nm torque. It provides a continuous current at standstill (100 K) of 17.6 A, a continuous torque at standstill (100 K) of 20 Nm, and a maximum current of 69.3 A. The servomotor supports a maximum speed of 6000 rpm, a maximum torque output of 66 Nm, and exhibits a winding inductance of 3.200 mH and resistance of 0.45 ohms. It is housed in an IP65 enclosure with Class 155 insulation, suitable for environments up to 40°C and 90% relative humidity. The unit has a thermal time constant of 54 minutes, a mass of 18 kg, and requires FN type cooling.

Frequently Asked Questions

How does liquid cooling improve motor reliability in demanding applications?

The liquid cooling maintains stable temperatures under heavy duty cycles. The consistent thermal balance extends motor life and reduces overheating risks.

What role does the holding brake play in precision automation systems?

The holding brake secures the shaft when power is off. The function ensures safe positioning during load handling and machine stops.

How does continuous torque at standstill influence machine design?

The ability to deliver stable torque at zero speed supports holding heavy loads. The characteristic is critical for robotics and press applications.

Why is maximum current rating important for peak load conditions?

The maximum current defines how well the motor can handle short bursts. The specification ensures system stability during acceleration or shock loads.

How does Bosch Rexroth Indramat MSK071D0450FN M1 UG2 NNNN compare for safety critical uses?

The motor includes a strong holding brake and precise feedback interface. The combination ensures accurate control in safety related machine functions.
