Product Description:

The MSK100A-0300-NN-M1-BP1-NNNN synchronous servomotor is built by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Within a drive system, it converts electrical energy from an IndraDrive inverter into controlled mechanical rotation, allowing axes to accelerate, decelerate, and hold position with feedback precision. The motor’s mechanical interface and encoder package make it suitable for automated tooling centers, pick-and-place gantries, and other production modules that require closed-loop speed and torque regulation over repeated positioning cycles.

Thermal management relies on natural convection, so housing fins must stay unobstructed for ambient air to remove waste heat. The enclosure is rated IP65, blocking dust and resisting low-pressure water jets, which permits cabinet-free mounting near the process. Continuous operation is permitted between 0 to 40 °C, keeping magnetic materials and insulation within safe limits. Feedback reaches the drive through a Hiperface interface, delivering position data and electronic motor data over a single feedback channel. With a physical frame identified as size 100, the unit shares mounting points with other A-length models in the series and retains the standard design outline.

The integrated optical encoder delivers 128 signal periods per revolution and stores positional history in a multiturn absolute format, so the axis retains its count after power is removed. An electrically released brake supplies 32 Nm of static holding torque, allowing vertical loads to remain stationary when the inverter is disabled. Mechanical power is transmitted through a shaft with keyway, a coupling style widely used on gearboxes and belt pulleys. Class 155 insulation permits higher winding temperatures before aging, and the 0300 winding code corresponds to resistance and inductance values suited to medium-torque duty cycles. The motor’s electrical terminals exit through the B-side power connector, and its A-length construction keeps overall depth minimal while preserving the natural-convection cooling corridor.
