Product Description:

The MSK101D-0450-NN-S2-BG0-RNNN is an AC synchronous servomotor produced by Bosch Rexroth Indramat for use in precision motion axes. It belongs to the MSK IndraDyn S Synchronous Motors series and converts drive-controller output into tightly regulated torque for automated equipment. This model’s role in industrial automation is to position tooling or conveyors with high dynamic accuracy, enabling shorter cycle times in assembly, packaging, and material-handling cells. Its electromagnetic design couples rare-earth rotor magnets with a stator winding identified by code 0450 to deliver consistent torque across the usable speed range, and that synchronous design supports quick response during acceleration, deceleration, and repeated direction changes.

Thermal management relies on natural convection, so heat dissipates through the housing without active fans, which simplifies installation and removes moving parts. Position feedback is supplied by an EnDat2.1 optical encoder that outputs 2048 signal periods per revolution, giving the controller high-resolution data for velocity control, commutation, and stable low-speed motion. The lamination stack is length class D, and the housing carries an IP65 rating, meaning it is dust-tight and resists water jets when sealed at the shaft and connector. Mechanical holding power is not provided because the motor is delivered without a holding brake, so any load that must remain fixed during shutdown needs a separate holding method.

Manufacturing tolerances described as increased concentricity keep runout low, benefiting applications that demand smooth rotation at high speeds. The feedback device is a single-turn variant, which supplies absolute position within one revolution and relies on external counting in systems that need multi-turn data. Electrical power reaches the windings through a connector mounted on the B-side, while motion is transmitted through a plain shaft that eases coupling to gearboxes or pulleys and can simplify machine-side packaging. The motor operates reliably in ambient temperatures from 0 to 40 °C and uses insulation system class 155, allowing the winding system to tolerate elevated internal heat without damaging the insulating materials.
