Product Description:

The MSK075E-0450-NN-M1-UG0-NNNN is an IndraDyn S synchronous servo motor built by Bosch Rexroth Indramat and part of the MSK IndraDyn S Synchronous Motors series. It serves as a precise rotary actuator for positioning and velocity control tasks in automated machinery, supplying closed-loop torque coordinated by a drive controller. This model uses frame size 075 and length code E to provide the torque density expected in medium-inertia axes while maintaining a standard design for cabinet-mounted or machine-mounted installations.

The motor relies on natural convection to move heat from the stator surface to the surrounding air, eliminating the need for forced-air or liquid cooling. A rotatable encoder connector with a 240° adjustment range simplifies cable routing in tight spaces, and feedback is exchanged through the Hiperface interface so the controller receives absolute position data. Inside the encoder, an optical reader produces 128 signal periods per mechanical revolution, allowing fine interpolation for smooth velocity control. The housing carries an IP65 rating that blocks dust and low-pressure water jets, so the motor can be mounted outside sealed cabinets in many plant environments.

The operating temperature range is 0 to 40 °C, and the winding insulation uses class 155 materials to resist thermal breakdown during continuous duty. A plain shaft couples the rotor directly to gearboxes or couplings without keyways, which helps reduce concentricity errors in high-precision axes. Because this unit is supplied without a holding brake, external means must secure vertical loads during power loss. Multiturn absolute sensing preserves position after disconnection, and the optical measuring method helps resist electromagnetic interference during startup. The winding code 0450 identifies the electrical values used by compatible drive controllers.
