Product Description:

Bosch Rexroth Indramat manufactures the MSK100D-0300-NN-S1-AP0-NSNN synchronous servomotor for precision motion control tasks. The unit is part of the MSK IndraDyn S Synchronous Motors series and is used to deliver commanded torque and speed to articulated robots, gantries, and other servo-driven axes in automated machinery. By combining a permanent-magnet rotor with a high-resolution feedback device, the motor allows the connected drive controller to regulate position with minimal following error. This operating concept makes the motor suitable for applications that need responsive acceleration, repeatable positioning, and stable low-speed motion.

Heat is removed by natural convection, so cabinet airflow or external fans are unnecessary provided the ambient stays within 0-40 °C. The housing carries an IP65 ingress rating, which helps keep dust and water jets away from internal components during operation. Electrical power reaches the stator through an A-side connector, and the motor uses size 100 with length designation D and winding code 0300. Rotor position is returned to the drive over a Hiperface interface, and the optical encoder generates 128 signal periods per revolution for smooth interpolation at low speeds.

The feedback element is single-turn, meaning it tracks absolute rotor position within one mechanical turn and then repeats, which is suitable for axes that reference during startup. Torque is transmitted through a shaft with a keyway, a conventional interface that helps couple the motor to pulleys or gearboxes without slip. Thermal endurance is supported by class 155 insulation, allowing the windings to tolerate elevated internal temperatures during cyclic loading. The motor follows standard and explosion protection design rules, and it is supplied without a holding brake, so an external device must secure the load when power is off.
