Product Description:

The MSK070D-0450-NN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical drive commands into controlled rotary motion for positioning and velocity loops in automated machinery. Its closed-loop use allows the drive to regulate acceleration, speed, and stopping with consistent response under changing loads. This operating role suits axes that need repeatable starts, stops, and direction changes during automated cycles. A rotatable 240-degree encoder connector eases cable routing, and the encoder operates in single-turn mode.

Heat generated by the stator is removed through natural convection, so unobstructed airflow must be maintained around the housing. The motor housing has an IP65 rating, which helps protect internal parts from dust and low-pressure water jets on plant floors. Mechanical output is transferred through a plain shaft, which supports direct coupling to gearboxes or driven loads. Position data is transmitted through the EnDat2.1 serial interface, and that optical feedback system provides 2048 signal periods per revolution for accurate position control. This single-revolution capture is suitable for homing routines carried out during each startup, and the increased concentricity design helps reduce radial runout at high speed.

Physical sizing follows MSK nomenclature. Frame 070 establishes the outer diameter, while length code D indicates the active stack height and torque potential. The winding code 0450 matches the electromagnetic design to compatible power modules. Continuous duty is approved for ambient temperatures from 0 to 40 °C, and insulation class 155 supports higher winding temperatures before accelerated aging occurs. Because the motor is supplied without a holding brake, the load must be secured by external clamping or static drive torque when power is removed.
