Product Description:

The MSK075E-0450-FN-M2-UG2-RNNN is a rotary servomotor from Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it supplies precisely controlled torque and position feedback for CNC axes, packaging machinery, and assembly lines where repeatable motion is required. The motor’s plain shaft couples directly to gearboxes or load shafts, while the integrated multi-turn encoder transmits absolute position data to the drive controller, making the unit suitable for closed-loop automation tasks that demand high positional accuracy.

The cooling code FN requires coolant to circulate through the housing, and the specified Liquid cooling path extracts heat more efficiently than surface convection alone. Frame code 075 indicates the stator diameter, and length code E adds extra stack height so continuous torque rises without enlarging the footprint. The winding code 0450 sets the resistance and inductance values that the IndraDrive supply must match for optimal current regulation. A permissible ambient span of 0 to 40 °C and an insulation system rated to class 155 permit continuous duty in typical factory climates. Increased concentricity of the rotor-stator set lowers cogging, improving speed ripple when the motor follows micro-increment commands.

The electrically released holding brake applies 30 Nm of torque to secure vertical axes during power loss, and the plain shaft eliminates keyseat stress in high-cycle couplings. Position data travel over the EnDat2.1 serial interface. The optical glass disk encoder provides 2048 signal periods, and Multiturn Absolute counting supports fine resolution across 4096 revolutions. A rotatable 240° connector lets wiring exit in the preferred direction, aiding cabinet layout. Environmental sealing reaches IP65 once the mating connectors are in place, which keeps out dust and low-pressure water jets. The liquid channels also help limit heat buildup around the bearing area.
