Product Description:

The MSK075E-0300-FN-S2-UG0-RNNN is a synchronous servo motor from Bosch Rexroth Indramat that belongs to the MSK IndraDyn S Synchronous Motors series. Intended for precision positioning and speed control, it works with IndraDrive amplifiers to move axes in packaging, handling, and metal-cutting equipment while delivering repeatable torque from a compact frame. It bridges mechanical loads to digital motion commands through an integrated optical feedback system, allowing accurate shaft movement during dynamic industrial cycles and other closed-loop motion tasks.

Its thermal management relies on liquid cooling, which circulates coolant around the stator so continuous output is not limited by cabinet airflow. This arrangement supports stable thermal behavior during continuous motion and reduces dependence on surrounding air conditions. The housing meets IP65, which helps keep out dust and water jets on the machine floor. An optical encoder supplies 2048 signal periods per revolution and transmits absolute data over EnDat2.1, allowing fine position interpolation in the drive. A plain shaft simplifies coupling and avoids keyway stress. Increased concentricity keeps the air gap uniform, while winding code 0300 sets the motor's electrical characteristics. Size 075 and length E indicate a 75 mm frame with an extended stack.

The feedback system is classified as Singleturn, so the drive reads absolute position within one mechanical revolution after power-up. The encoder connector is rotatable, 240°, which helps route the cable in tight enclosures and in spaces where the cable exit direction is restricted. Continuous duty is permitted between 0–40 °C, and the insulation system is rated at 155, providing thermal margin during sustained current demand. The motor is supplied without a holding brake, so any standstill holding force must come from the drive or the machine.
