Product Description:

The MSK075E-0300-NN-M1-UP2-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is used on positioning and traversing axes where rapid torque response and closed-loop motion accuracy are required in automated machinery. Its synchronous design supports precise coordination with the drive so commanded position changes can be followed accurately during dynamic operation. The motor is suited for applications that need repeatable acceleration, controlled speed changes, and stable feedback during cyclic operation, such as indexing tables, packaging axes, and transfer units.

The housing carries a protection rating of IP65, so dust is kept out and water jets cannot reach active parts. Heat is removed by natural convection; the FN cooling code indicates that no fan or liquid circuit is present, so the installation should allow free airflow around the housing. Compact geometry comes from motor size code 075 and length code E, which helps keep inertia low while accommodating the 0300 winding. Mechanical power is delivered through a shaft with a keyway, and the stator is insulated for operation in ambient temperatures of 0–40 °C. This output style allows direct use with common couplings and timing-belt pulleys where positive torque transfer is needed.

For static holding and emergency stops, an electrically released brake supplies 30 Nm of torque and engages automatically when power is removed. Multi-turn feedback is obtained from an optical encoder that provides 128 signal periods per revolution and communicates over the Hiperface interface. The connector can be rotated through 240° to simplify cable routing in tight machine spaces, and the encoder supports accurate position control during low-speed movement. The insulation system is rated to class 155, allowing the windings to tolerate elevated operating temperatures without premature deterioration.
