The Indramat MPN R911324412 (MSK050C-0450-NN-S2-UG0-RNNN) is an AC synchronous servomotor designed for demanding automation applications. This model features a winding code 0450, operates with natural convection cooling, and is encased to the IP65 protection standard. It delivers a continuous standstill current of 5.2 A with 5.5 Nm torque at 100 K, reaching up to 15.0 Nm maximum torque and 18.8 A peak current. The unit includes a plain shaft with shaft sealing ring per DIN 6885-1, no holding brake, and utilizes an optical singleturn EnDat2.1 encoder (2048 signal periods), with a rotatable 240° encoder connector. The design prioritizes increased concentricity and compact build (motor size 050, length C).
