Product Description:

The MSK075E-0450-NN-S1-UP0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within an automation cell, it functions as the torque source for servo axes that demand precise speed and position control, providing repeatable motion for feeders, pick-and-place heads, and indexing tables. Its synchronous design allows the drive to regulate rotor position closely during indexing, transfer, and other coordinated motion tasks. The motor is intended for applications that require stable axis response throughout repeated operating cycles.

Heat is removed through natural convection, so the housing dissipates thermal energy without fans or liquid circuits. The motor has a standard design, a size 075 frame, and length E, while winding code 0450 is paired with this arrangement for the intended torque and inertia range. Position feedback is generated by an optical encoder that delivers 128 signal periods per revolution, and the measurement is transferred through the Hiperface interface. The encoder supports single-turn position tracking, and its connector can be rotated 240° to simplify cable routing in confined machine spaces. Because cooling is passive, the motor can be used where additional airflow hardware is not desired. The enclosure is rated IP65, which helps protect internal parts from dust and low-pressure water jets.

The motor is supplied without a holding brake, so external clamping or drive-applied torque is needed when a stopped load must be held in place. Acceptable ambient operation spans 0 to 40 °C, which fits common industrial installation conditions. Mechanical power is transmitted through a shaft with keyway, allowing secure coupling to pulleys or gearboxes. The windings use insulation class 155, supporting elevated internal temperatures during continuous duty. This arrangement is suitable for machines that use external braking hardware instead of an integrated brake assembly.
