Product Description:

The MSK100B-0450-NN-S1-AP1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and supplied as part of the MSK IndraDyn S Synchronous Motors series. It is built for servo-controlled positioning and speed regulation in industrial automation lines, where closed-loop encoder feedback helps the drive hold commanded motion profiles with minimal error. This type of motor suits axes that require coordinated starts, stops, and speed changes under closed-loop control. The motor uses stator length B in the standard MSK housing profile, and it has a keyed shaft for positive torque transfer. Its power connector is positioned on the A-side, which supports straightforward cable routing in many machine layouts.

The motor removes heat through natural convection, so no external blower or liquid circuit is required during operation within its rated range. Position feedback is delivered over a Hiperface interface, and the optical sensor provides 128 signal periods per revolution for motion control. That feedback arrangement supports stable commutation and precise speed regulation across the servo axis. Because the scanning system is single-turn, the encoder retains absolute position within one mechanical revolution. An electrically released brake is integrated, and it can hold the shaft with 32 Nm of static torque during power-off states. The windings use insulation class 155 for thermal duty.

The housing is sealed to IP65, allowing use in dusty or splash-prone areas without an additional enclosure. Its sealed construction also helps protect internal bearings and encoder components from common shop contamination. The motor has a size of 100, and winding code 0450 matches the electrical characteristics expected by compatible IndraDrive units. Continuous service is permitted in ambient temperatures from 0–40 °C, where the naturally cooled frame can dissipate normal operating losses. These temperature conditions also keep the encoder optics within their intended accuracy range.
