Product Description:

The MSK070D-0150-NN-M2-UG1-RNNN is a synchronous servo motor developed by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servo motor, it converts inverter-supplied electrical energy into rotary motion with high positional accuracy, supporting tightly coordinated movement in material-handling cells and automated assembly lines. Because the encoder retains absolute position values, motion control can resume after power outages without a homing routine.

Heat generated by the stator windings is removed through natural convection, so the motor can be mounted without forced-air ducts or external coolers when ambient airflow is available. The mechanical package uses the increased concentricity option, which reduces shaft runout and helps keep coupling misalignment low. For flexible installation, the encoder plug is rotatable through 240°, letting cables exit in several directions inside crowded cabinets. Position feedback travels over the serial, bidirectional EnDat2.1 interface, and the optical scanning system resolves 2048 signal periods per revolution at the code disc, offering fine interpolation for precise positioning. The optical principle avoids magnetic hysteresis, and its electronic multiturn counter records revolutions without a battery.

Power-off safety comes from an electrically released holding brake that can lock the rotor with 23 Nm of static torque when the supply is removed. The transmission interface is a plain shaft, so torque is passed directly through compression couplings or toothed belt pulleys without keyways. Dimensional codes identify the servo motor as frame size 070 with length category D, and this compact envelope eases mounting in multi-axis gantries. Winding code 0150 indicates the copper fill and stator impedance, allowing compatible IndraDrive controllers to apply rated current without exceeding thermal limits.
