Product Description:

The MSK101E-0300-NN-M1-AP2-NNNN is an AC servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It converts drive current into regulated torque and speed for automated packaging, printing, and material-handling equipment that requires repeatable motion. In closed-loop operation, the motor responds quickly to changing commands so indexing, feed, and transfer axes can maintain stable speed and position. An onboard encoder allows the drive controller to monitor absolute rotor position and execute precise profile moves, while the size 101 housing with length code E fits common medium-power machine layouts.

Cooling is handled by natural convection, so ambient airflow removes heat without auxiliary fans. Electrical feedback is transmitted through a Hiperface interface with optical scanning, and the encoder disk provides 128 signal periods for fine angular resolution. The electrically released holding brake supplies 70 Nm of static torque, which helps secure vertical or suspended loads when the power stage is disabled. The motor has an IP65 enclosure that resists dust ingress and water jets during normal industrial use. Power is connected on the A-side, and winding code 0300 identifies the electrical winding used for this model.

The encoder operates as a multiturn absolute device, so position information is retained across power loss and the drive can recover shaft position without a reference move after restart. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, which matches typical indoor machine conditions. Mechanical output is transferred through a shaft with a keyway, allowing direct coupling to gearboxes or timing pulleys with positive torque transmission. The motor uses insulation class 155, which supports the thermal limits expected for this design. A keyed shaft can also simplify the use of hubs or pulleys that rely on positive mechanical engagement.
