Product Description:
The MSK100B-0200-NN-S2-BG0-RSNN is a synchronous servo motor produced by Bosch Rexroth Indramat and included in the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop drive axes in packaging lines, handling robots, and machining centers where precise torque and position control are required. With frame size 100 and length B, the motor offers a balanced combination of inertia and output for compact machine layouts. Its synchronous design supports accurate speed regulation and repeatable positioning during rapid start-stop cycles. This makes it suitable for indexing applications, pick-and-place motion, and other coordinated axis tasks where stable response is important.
Heat generated by the stator windings is removed through natural convection, so the housing must be mounted where free airflow is available and no forced-air blower or liquid circuit is required. Position feedback is supplied by an optical encoder that communicates over the EnDat2.1 interface and delivers 2048 signal periods per mechanical revolution, supporting fine interpolation inside the drive for smooth velocity profiles. Because the measuring system is single-turn, absolute position information is available within one full shaft revolution. The enclosure carries an IP65 rating, which helps protect the motor from dust and low-pressure water jets when it is installed on open machine frames. This feedback and enclosure combination supports reliable motion control in machines that need precise positioning and a sealed motor housing.
The motor uses a plain shaft for direct coupling to gearboxes or belt pulleys, and electrical power is routed from the B-side of the housing to support orderly cable routing. It is supplied without a holding brake, so static load retention must be provided by an external device or by drive-generated torque when the application allows it. The rotor runs with increased concentricity, and the unit is approved for use in areas that require explosion protection. This arrangement can be useful where a clean shaft interface is preferred and where separate load-holding hardware is already part of the machine design. The winding uses insulation class 155, permitting continuous operation at ambient temperatures from 0 °C to 40 °C when used within the motor’s thermal operating range.
