Product Description:

The MSK100C-0300-NN-S1-AG2-NNNN is an AC servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It serves as the driving element for position-controlled axes in industrial automation, converting commanded current from a Rexroth inverter into precise mechanical motion. The synchronous construction keeps rotor speed locked to the drive’s output frequency, enabling accurate interpolation, contouring, and coordinated multi-axis work in assembly cells, packaging stations, and metal-cutting machines. When paired with a compatible inverter, the motor supports rapid acceleration, stable speed regulation, and repeatable positioning on axes that must start, stop, and reverse under changing loads.

Cooling relies on natural convection, so heat dissipates through the finned housing without fans, and installation must allow unobstructed vertical airflow. Position feedback uses a Hiperface interface, and an optical sensor reads a code disk with 128 signal periods to provide high-resolution electrical angle data. The encoder is single-turn, delivering an absolute position for one revolution before resetting. An electrically released brake supplies 70 Nm of holding torque to secure loads when the drive is disabled. Power and protective earth conductors connect on the A-side, keeping cable entry on one end of the stator for straightforward panel routing.

The mechanical frame corresponds to size 100 and a C length body, which provides space for active materials that support sustained torque output. Its stator carries the 0300 winding, matching the current and voltage characteristics used on medium-inertia axes. A plain shaft interface transfers torque through clamp or shrink couplings, which helps maintain concentric alignment and avoids keyway stress points. The standard housing, encoder cover, and seal arrangement support the convection-cooling layout while helping the motor remain suitable for enclosed machine installations. This layout also helps the motor fit applications where orderly cable access and compact machine integration are important.
