Product Description:
The MSK101D-0450-NN-S2-LG2-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It serves as a direct-coupled drive element that supplies repeatable torque and position feedback for coordinated motion loops in industrial automation. The motor uses a size 101 stator frame with the D length option, which increases continuous power without enlarging the mounting footprint. Its plain shaft couples directly to pinions, pulleys, or rigid flanges, keeping the mechanical interface compact and reducing the need for keyed connections in tightly packaged machines.
Heat is removed by natural convection, and installation should follow the FN cooling arrangement so ambient air can circulate freely around the housing. Position data is produced by an optical encoder that communicates through the EnDat2.1 interface. The encoder provides 2048 signal periods, and its single-turn design repeats the absolute position after one mechanical revolution. An increased concentricity design minimizes shaft shoulder runout, which helps support smoother interpolation on high-precision paths. Electrical holding during downtime is provided by an electrically released brake rated at 70 Nm of static torque. Power enters on the left side, which can simplify cable routing where several axes share the same cabinet or cable path.
The motor housing has an IP65 rating that protects the windings and bearings against dust ingress and low-pressure water jets. Reliable service is intended for ambient temperatures from 0 to 40 °C, and the insulation system meets class 155 for thermal durability during normal operation. Winding code 0450 identifies the electrical characteristics that must match the drive controller for field-oriented control. This combination of sealing, thermal capability, and matched winding data supports stable operation in enclosed machinery, transfer systems, and other motion applications that require accurate servo response.
