Product Description:

The MSK131D-0202-NN-S3-AG0-NPNN is a servo motor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts electrical power from a drive into controlled mechanical rotation for positioning axes, gantries, and processing heads in automated machinery. The flange-mounted design allows direct coupling to gearboxes or load shafts, and its compatibility with IndraDrive controllers places it within closed-loop motion systems that require precise torque and speed regulation. This layout supports accurate response during repeated starts, stops, and speed changes in automated equipment.

The motor frame corresponds to a 131 size with a D length code, giving it a higher magnetic volume than shorter variants. Stator windings follow code 0202, which indicates the electrical winding arrangement used with compatible drives. Heat is removed by natural convection, so no external blower or liquid loop is required, but installation clearances must allow rising air to pass along the housing fins. A housing rated IP65 keeps dust and water jets away from internal laminations, and the plain shaft simplifies coupling with backlash-free clamping hubs while reducing stress concentrations associated with keyways.

Feedback data travel over the Hiperface interface to the drive, where a capacitive single-turn sensor delivers rotor position every 16 signal periods per mechanical revolution. This digital feedback supports high-gain current loops without the magnetic drift seen in analog encoders. The allowable ambient range of 0 to 40 °C helps protect Class 155 insulation materials from thermal aging when the motor is cooled only by convection. Power is supplied through an A-side connector that keeps the cable run separate from encoder lines, and the absence of a holding brake reduces inertia for axes that are clamped externally during standstill.
