Product Description:

The MSK075E-0450-NN-M1-UP1-NNNN is part of the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. As an IndraDyn S servomotor, it converts electrical power into tightly regulated mechanical motion for automated positioning and velocity loops on machining centers, printing presses, and pick-and-place modules. Its size 075 housing and length code E provide a compact form factor for medium-inertia drive trains. The motor is intended for applications that need accurate torque response and stable speed regulation during repeated motion cycles.

The stator windings use the 0450 code and are cooled by natural convection, so airflow around the frame removes heat during continuous duty. A protection rating of IP65 helps prevent dust and water jets from reaching internal components. The motor can run in ambient temperatures from 0 to 40 °C without derating, and its Class 155 insulation system tolerates winding hot-spot temperatures up to 155 °C. An electrically released holding brake supplies 23 Nm of static torque to lock vertical or indexing axes whenever the drive is disabled. Rotor position feedback is captured by an optical encoder with 128 signal periods per revolution, which supports fine commutation and responsive control.

Cabling flexibility is aided by a 240° rotatable connector that lets the plug be oriented in confined spaces. The servo communicates over the Hiperface protocol, so encoder information, the multiturn counter, and temperature data share the same signal connection. Absolute position is retained by a multiturn absolute measuring system, which eliminates homing after power loss. Mechanical power is delivered through a shaft with keyway, allowing rigid coupling to pulleys or gearboxes. This layout supports closed-loop motion while keeping the mechanical interface straightforward.
