Product Description:

The MSK101D-0450-NN-S1-AG2-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S series. As an AC permanent-magnet unit, it converts drive current from IndraDrive controllers into controlled torque and speed for positioning tables, packaging axes, and material-handling gantries. Integrated feedback hardware supports closed-loop operation, allowing the motor to maintain accurate motion with low following error during positioning and speed-controlled tasks. This motor is suited for automated equipment that requires repeatable starts, stops, and speed changes during continuous machine operation.

The motor includes an electrically released holding brake with 70 Nm of holding torque, allowing vertical axes to remain stationary when power is removed. Heat is removed by natural convection, and the housing carries an IP65 rating that resists dust and low-pressure water jets. Feedback is transmitted through a Hiperface interface, and the integrated optical system provides 128 signal periods per revolution for position data used by the drive. Cooling type FN requires unobstructed airflow around the housing fins so the motor can dissipate heat correctly during operation.

The motor uses frame size 101 with frame length D, giving it a longer active section for higher continuous output within this housing family. Winding code 0450 matches the motor's electrical characteristics to compatible drive settings, and insulation class 155 supports elevated winding temperatures within normal thermal limits. Continuous operation is permitted from 0–40 °C, and higher ambient temperatures require derating. The motor has a plain shaft for coupling to low-backlash gearboxes, and the power connection exits on side A for compact cable routing in tightly enclosed machine layouts.
