Product Description:

The MSK100D-0300-NN-S1-AP0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This motor serves as a rotary actuator for positioning and velocity control tasks in automated machinery, where closed-loop feedback and high torque density support precise motion regulation. It is well suited for axes that require repeatable acceleration, controlled stopping, and stable speed regulation during cyclic machine motion. The motor belongs to size 100, which places it in a medium-frame format for servo applications. Its construction length is coded as D, giving the unit a form factor suited to balanced torque output and installation space.

Thermal management uses natural convection, so the housing dissipates heat without forced airflow. This simplifies cabinet layout and avoids the extra wiring and service needs associated with separate fan hardware. Rotor signals are transmitted through a Hiperface interface, which carries position and parameter data directly to the drive. The digital feedback path supports accurate commutation and coordinated motion control during changing load conditions. Inside the encoder, an optical disc provides 128 signal periods per revolution to support smooth velocity profiling. The motor uses a standard design, and cooling fins are integrated into the casting so no external fan kit is required.

The encoder is a single-turn unit, so it reports absolute position within one mechanical revolution while the drive tracks additional turns as the axis moves. Power conductors terminate on the motor's A-side, which can simplify routing when the cable run must stay on one side of the machine. Mechanical coupling is handled through a shaft with a keyway, allowing positive torque transfer to matched hubs, pulleys, or gear inputs. The electromagnetic circuit uses winding code 0300, which sets the voltage constant and nominal speed range for general-purpose servo axes. Because the motor is supplied without a holding brake, the load must be secured by drive torque or an external locking device during power-off conditions.
