Product Description:

The MSK100A-0300-NN-S1-BP1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts drive commands into precise rotary motion for gantry, packaging, and handling axes in automated lines. The motor follows the standard mechanical design of the series, uses a keyed shaft for slip-free torque transfer, and receives three-phase power through a rear B-side connector. That connector position helps keep cabling at the back of the motor, which is useful in compact machine layouts with limited space near the load side.

Laid out for moderate thermal loads, the unit relies on natural convection, so heat leaves through the finned housing without fans or liquid circuits. Environmental sealing meets IP65, keeping dust and water jets away from internal windings during normal industrial use. The stator uses winding code 0300, which matches the electrical characteristics expected by the drive. Position feedback is transmitted over a Hiperface link that carries absolute angle data from the optical sensor. During power-off, the electrically released brake holds the shaft with 32 Nm, which helps prevent drift on vertical or suspended axes.

Permissible operation spans 0–40 °C, matching typical factory climates and supporting the passive cooling method. The motor has a frame size of 100, and the A-length housing keeps the overall depth short for tightly packed machine frames. High-resolution commutation comes from an optical encoder that outputs 128 signal periods per revolution and stores single-turn absolute data, so the axis can report position without a homing move after startup. An insulation system rated 155 supports elevated winding temperatures during rapid duty cycles while helping protect the motor windings from premature thermal stress.
