Product Description:

The MSK101D-0450-NN-M3-AP0-NNNN is a servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Supplied as a standard design unit, it converts regulated drive output into precisely metered torque for indexing tables, gantry axes, and other motion stages in industrial automation. Direct electrical commutation together with internal feedback lets the motor hold commanded angles within tight tolerances, even under variable load. Its compact envelope supports space-constrained installations, and the keyed shaft simplifies mechanical coupling to gearboxes or pulleys without custom hubs. It is suited to servo axes that must accelerate, decelerate, and settle quickly while maintaining precise control over position and speed.

The motor relies on natural convection cooling, so heat dissipates through the housing without external blowers. An enclosure rating of IP65 prevents dust and low-pressure water jets from reaching internal components. Position data is delivered through a Hiperface interface, which transfers feedback data to the drive. Inside the encoder, a capacitive sensing element generates 16 signal periods per mechanical revolution, and those periods are interpolated for finer angular resolution. The encoder is multi-turn absolute, so shaft position and full-turn count remain available after power is removed. The unit is built in size 101 with length D, its power leads exit on the A-side connector, and it is supplied without a holding brake, so external hardware must secure static loads when power is off.

The motor operates in ambient temperatures from 0–40°C, allowing continuous duty in standard machine-room climates. Insulation Class 155 protects the stator windings from thermal aging during repetitive acceleration cycles. Winding code 0450 matches the electrical characteristics expected by compatible IndraDrive power modules. That combination helps the drive maintain smooth torque delivery during frequent reversals and short indexing sequences. It also supports stable operation during long production runs where thermal buildup must remain controlled.
