Product Description:

Bosch Rexroth Indramat manufactures the MSK101E-0300-NN-M1-LG2-NNNN servomotor for the MSK IndraDyn S Synchronous Motors series. This standard-design IndraDyn S synchronous servomotor converts drive current into controlled mechanical rotation for positioning tasks on packaging lines, gantry axes, and material-handling stages. Integrated digital feedback allows a controller to command speed and position within tight tolerance while the sealed housing protects the stator and rotor from dust and spray.

The motor includes an electrically released holding brake that applies 70 Nm of static torque, allowing vertical or suspended loads to remain stationary when power is removed. A cast-aluminum housing with an IP65 rating blocks dust ingress and water jets so the encoder and windings are not exposed during washdown or coolant spray. Position feedback is provided through a Hiperface interface; its optical reader produces 128 signal periods per mechanical revolution so the drive can interpolate fine incremental positions. Continuous operation is specified for ambient air from 0 to 40 °C, ensuring thermal margins are maintained without derating in most shop-floor climates.

Heat is removed by natural convection, a requirement identified by the Cooling FN designation, so external fans or liquid jackets are not necessary provided that free airflow surrounds the frame. The encoder stores position across multiple rotations by using multi-turn absolute technology, preventing loss of reference after a power cycle. Mechanical power is transmitted through a plain shaft that matches couplings without keys, and electrical supply reaches the stator through a left-side connector that simplifies cable routing in tight cabinets. The winding code 0300, insulation system class 155, motor size 101, and length code E indicate the electromagnetic package used with compatible IndraDrive servo amplifiers.
