Product Description:

The MSK075E-0300-FN-S1-UG0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and speed regulation on conveyor axes, packaging gantries, and general automation equipment, where dependable torque and precise feedback are required to execute programmed motion profiles. Its 075 frame size and extended E length give it a mid-range mechanical envelope that fits inside compact machines while still accommodating the magnetic stack length needed for elevated continuous power.

This model relies on liquid cooling, so heat is extracted through an internal channel that circulates coolant rather than ambient air, enabling higher continuous torque at stable winding temperatures. Its plain shaft offers a smooth cylindrical interface for couplings or gearboxes, reducing runout compared with keyed versions. Position data are generated by a Hiperface-compliant absolute encoder. The sensor produces 128 signal periods per revolution, and the drive interpolates these signals for fine angular resolution suited to precision indexing. Because the sensing principle is optical, the feedback remains unaffected by stray magnetic fields, which is valuable when multiple motors operate in close proximity.

The single-turn arrangement reports absolute position only within one mechanical turn, which simplifies homing routines in applications that do not require multi-turn tracking. During installation, the encoder connector can be rotated through 240°, allowing the cable exit to be aligned with the machine frame and helping avoid sharp bends. The motor is supplied without a holding brake, so any vertical axis must rely on external locking devices or static torque from the drive. Length code E uses an extended active stack, while winding code 0300 corresponds to resistance and inductance values that match the current capability of IndraDrive power stages.
