Product Description:

The MSK101E-0300-NN-M2-AP2-RNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It supplies controlled torque and speed to automated axes, conveyor drives, and handling stations in industrial machinery. This creates a direct electromechanical link between the Rexroth drive amplifier and the machine load, so commanded motion can be transferred to the axis with accurate rotary response. It is suited for coordinated motion tasks that require steady servo behavior during repeated machine cycles.

Thermal management relies on natural convection, so the installation must allow unobstructed ambient airflow around the housing. The stator winding is coded 0300, and the rotor uses an increased concentricity design that limits radial runout for smooth rotation at changing speeds. An optical multi-turn encoder communicates over EnDat2.1 and produces 2048 signal periods per mechanical revolution, giving the controller fine incremental and absolute position data for commutation and axis control. An electrically released holding brake delivers 70 Nm of static torque to secure the shaft during emergency stops or power loss. The housing has an IP65 ingress rating, which keeps out dust and withstands low-pressure water jets encountered during routine cleaning.

The permitted ambient range is 0-40 °C, and the insulation system uses class 155 materials to tolerate elevated winding temperatures without accelerated aging. Drive torque exits through a shaft with a keyway, allowing direct coupling to pulleys or gearboxes that need positive torque transmission. The A-side power connector guides the motor cable away from moving components to reduce strain and help keep routing clear. Mechanical dimensions follow size 101 with length E, which gives the motor a long housing format within this frame. The increased installation length can be useful where the axis layout already provides sufficient axial clearance around the motor body.
