Product Description:

The MSK101E-0300-NN-S1-AG3-NNNN servomotor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts commanded drive current into precise rotary motion for positioning axes, packaging machinery, and material-handling stations in industrial automation. Its 101 frame size and standard mechanical design allow direct integration with modular machine platforms that rely on Rexroth drive technology. The motor is intended for closed-loop servo operation with compatible drives that regulate torque, speed, and position during repeated motion cycles.

The motor uses natural convection for thermal management, so waste heat leaves the aluminum housing through surface exposure without auxiliary blowers. A sealed housing rated IP65 prevents dust penetration and guards against low-pressure water jets, allowing the unit to operate outside a cabinet when required. For vertical or suspended loads, an electrically released brake supplies 120 Nm of holding torque and locks the shaft when power is removed. Position feedback comes from an optical single-turn encoder with a Hiperface interface, and this digital link carries absolute position, stored motor data, and commutation signals to the drive. The encoder disk delivers 128 signal periods per mechanical revolution to support fine interpolated resolution in the control loop. The motor uses a size 101 frame with motor length E, an A-side power connector, and a standard construction style.

Continuous duty is permitted in ambient temperatures from 0 to 40 °C, which supports normal service life without derating under standard operating conditions. The output uses a plain shaft, which eliminates keyways or splines and helps minimize runout during high-precision coupling. Stator insulation is built to class 155, allowing the windings to tolerate elevated internal temperatures before thermal aging accelerates. Electromagnetic behavior corresponds to winding code 0300, so the matching drive can be set for the electrical characteristics of that coil family. This winding selection helps the controller match current response to the motor during acceleration and steady operation.
